This document summarizes a study that investigated using carbon fiber reinforced polymer (CFRP) strips to strengthen timber beams. Five deodar wood beams were tested: one unreinforced control beam and four beams strengthened with CFRP strips of varying widths applied to the bottom surface in tension. The CFRP strengthening significantly improved the beams' load-carrying capacity, with increases in maximum flexural strength ranging from 18% to 71%. Testing showed that combining CFRP reinforcement for both flexure and shear led to the greatest improvements in beam strength and represented an effective technique for reinforcing or rehabilitating existing timber structures.
The document summarizes research on strengthening timber beams with carbon fiber reinforced polymer (CFRP) plates to improve ductility. Ten timber beams of two species were tested: two unstrengthened control beams and eight beams strengthened with CFRP plates of varying widths. Testing showed that CFRP strengthening significantly increased the strength and ductility of timber beams. The highest increases in strength were 114% and 140% for deodar and kail wood species, respectively. Ductility index also improved dramatically, with maximum values of 6.81 for deodar and 4.33 for kail. The optimum CFRP area for maximum ductility was found to be 0.59% of the total cross-sectional area

Structural Engineering Properties of Fibre Reinforced Concrete Based On Recyc...IJERA Editor
Glass fibre reinforced plastics (GFRP) based on resin recovered from recycling plastic waste has been shown to possess mechanical properties satisfying normative requirements. This paper investigates the flexural behavior of concrete beams reinforced with GFRP produced from resin recovered from recycled plastic wastes. A total of fifteen of beams of sizes 150 ×150 ×900mm and 100 × 100 × 500mm reinforced with GFRP made from recycled glass fibre reinforced polymer was tested. The flexural test results yielded lower ultimate load, lower stiffness and larger deflections at the same load when compared with the control steel reinforced beam. However, the ultimate flexural strength of beams, reinforced with GFRP from recycled resin was at least four times higher than that of the control unreinforced beam. This is in agreement, quantitatively and qualitatively, with the trend of these parameters in GFRP reinforced concrete based on virgin resins. The results therefore confirm the applicability for structural uses with the accompanying benefits of wealth creation, value addition and environmental sustainability.

In recent years, the use of composite structures with Glass Fibre Reinforced
Plastic (GFRP) material has increased greatly due to its non-corrosive, nonconductive,
high strength-to-weight ratio, relevant fatigue endurance and cost
competitiveness. In this paper, the dynamic behavior of beams reinforced with GFRP

tested against horizontal loading pattern using the software ANSYS 16.1.
Characteristics of composite beam viz. stiffness and displacement are studied against
vibrations and frequency, respectively, against conventional beam. Analytical results
of ANSYS 16.1 software are i) beams with 16 mm GFRP material placed at tension
shown less displacement ii) beams with 16 mm GFRP material placed at tension zone
shown an increase displacement of 14.2% over conventional beam but with maximum
frequency of 100Hz iii) beams with 10 mm and 12 mm GFRP material placed at
tension zone shown less variations in their displacements iv) for a similar
displacements, beams with GFRP material shown lesser frequency than conventional

IRJET- Strengthening of Steel Fiber Reinforced Beams using GFRPIRJET Journal
This document summarizes an experimental study that investigated strengthening steel fiber reinforced concrete beams with glass fiber reinforced polymer (GFRP) sheets. Five beams were cast - one control beam and four beams wrapped with GFRP at different orientations. All beams were tested under two-point loading. The results showed that wrapping GFRP at the sides and bottom of the beam increased its initial cracking load and ultimate load capacity compared to the control beam. Wrapping GFRP at the sides only provided a 10% increase in load capacity over the control beam. In general, GFRP wrapping improved the load carrying capacity of the steel fiber reinforced concrete beams.
Strengthening of RC Beam using Polypropylene Fiber Sheet and Rubberized Coir ...IRJET Journal
This document describes a study on strengthening reinforced concrete beams using polypropylene fiber sheets and rubberized coir fiber sheets. 12 beams were cast and tested under two point loading. Beams were wrapped at the bottom or in a U-shape up to the neutral axis using 2mm or 4mm thick fiber sheets. Load-deflection behavior was studied until failure. The flexural strength of wrapped beams was compared to control beams and between fiber types. Finite element analysis of control beams was done using ANSYS software. Results showed that wrapped beams exhibited higher load capacity and stiffness compared to unwrapped beams. Wrapping with 4mm thick fiber sheets performed better than 2mm thick sheets.
1) The document describes an experimental investigation of glass fibre reinforced plastic (GFRP) bridge deck panels subjected to static and fatigue loading.
2) Testing of prototype GFRP composite bridge deck panels was conducted under simulated wheel loads, with two rectangular patch loads applied symmetrically.
3) The results showed that under buckling criteria, panels failed at 123.6 kN with a deflection of 7.538mm, and under local shear criteria panels failed at 113.8 kN with a deflection of 4.057mm. Panels also resisted up to 5 million fatigue cycles.
This research work mainly investigates the local production of 12 built up GFRP I-beams using Hand Lay-Up production method (since up-till now there is no pultrusion industry in Egypt). Overall strength characteristics of these beams will determined experimentally and compared to those manufactured by the Pultrusion process. This comparison will help to estimate to how extent the locally manufactured beams (by Hand Lay-Up technique) can be used in full permanent structures (like pultruded beams) or at least used in light and temporary structures. In order to achieve this goal, the experimental study was divided into two stages: The first stage is to manufacture GFRP plates using glass fibers and polyester. Two types of plates were produced one for flange plates and the other for web plates. These two types of plates are different in fibers orientation of different layers within the plate thickness in order to reach the possible higher tensile and flexural strength for flange plates and possible higher shear strength for web plates. Longitudinal and transverse tensile, compressive, and flexural strength for these two types of plates were experimentally determined using coupons tests. The second stage is to produce built-up GFRP I-beams using the aforementioned plates and composite angles. The overall stiffness and modes of failure of these beams were experimentally determined. The obtained results were compared with those of pultruded I-beams manufactured in the United States by pultrusion process. Also three different connecting methods for the 12 tested beams were investigated, namely: Bonding – Bolting – Bolting/Bonding connecting techniques. Of course it is expected that some local fabrication parameters (like fiber and polymer properties available in the local market, labour, temperature, polymer curing …etc) are expected to affect the properties of the fabricated beams specially that these beams are manufactured manually.

This document summarizes research on strengthening reinforced concrete beams with fiber reinforced polymer composites. It reviews 11 previous studies that investigated using glass or carbon fiber reinforced polymer sheets to strengthen beams against flexural or shear failure. The document then describes an experimental study involving two sets of beams: one set weakened in flexure and strengthened with glass fiber sheets, and one set weakened in shear and strengthened with glass fiber sheets.

EXPERIMENTAL STUDY OF RETROFITTED RC BEAMS USING FRPAM Publications
In order to improve the performance of reinforced cement concrete structure (RCC) it is better to repair or upgrade the structure by retrofitting. Retrofitting is one of the best options to make an existing inadequate building safe against future probable earthquake or other environmental forces. Retrofitting is the modification of existing structure to make them more resistance to seismic action, motion of ground and failure of soil due to earthquake or other natural calamities such as tornadoes cyclones and winds with high velocity caused by thunder storm, snow fall, hailstorms, etc. The study investigate the improvements in the structural behaviour of the RC beams retrofitted with various types of FRP such as glass fibres, coir fibres, banana fibres, jute fibres and cotton fibres. The experimental programme includes strengthening and flexural strength test of 18 simply supported RC beams of 500x100x100 mm. The test results showed an increase in ultimate load for the retrofitted beam when compared to normal control beam and corresponding increase in the value of modulus of rupture. The retrofitted beams with glass fibre using epoxy as binder having 47.32% more strength than the control beams. Area under load-deflection curve gives toughness. Toughness value is found to be more in RC beams retrofitted with banana fibre.

ABSTRACT: This paper attempts to develop a prediction model that can be used in line with prescribed laboratory experiments for indirect tensile test such that tensile elastic modulus can be predicted for cement stabilized lateritic soil reinforced with steel fiber using measured properties of the material. The results of the tensile elastic modulus obtained from the Derived Prediction Model almost nearly replicates that obtained from calculations from laboratory experimentation. Results obtained revealed that both the predicted values and calculated values have a linear correlation with an R2 of 96.4%. On this basis the Derived Prediction Model can be said to be valid within the limits of the study.

IRJET- Study on Hybrid Glass/Carbon Fiber Reinforced Vinyl Ester Polymer Comp...IRJET Journal
This study examines hybrid glass/carbon fiber reinforced vinyl ester polymer composites. Glass fiber and carbon fibers are chosen as reinforcements for their properties, while vinyl ester resin is selected as the polymer matrix. The document provides background on these materials, including that glass fiber is low-cost and isotropic, carbon fiber is very stiff with low density, and vinyl ester resin has high strength and corrosion resistance. Previous research found that hybrid composites can achieve optimized properties by combining different fiber types and that fiber parameters like length, orientation, and diameter influence mechanical characteristics. The goal of this study is to investigate these hybrid composites and how fiber properties affect their mechanics.
Flexural rigidity is a measure of the stiffness of textile fibers and fabrics. It depends on properties of the fibers like the modulus and diameter as well as the structure and properties of the yarns and fabrics. For knitted fabrics, flexural rigidity increases with increasing amounts of stiffer fibers like polybutylene terephthalate. It affects properties like handle, drape, creasing and wear performance. Flexural rigidity is important for applications requiring stiffness like industrial fabrics. It can be experimentally measured using a cantilever bending technique. The flexural rigidity of fabrics depends on parameters like yarn diameter and count, weave structure, and the flexural rigidity of the constituent yarns.
Exposure to elevated temperatures and cooled under different regimes a stud...eSAT Journals
Abstract Fire is one of the most destructive powers to which a building structure can be subjected, often exposing concrete elements to elevated temperatures. The relative properties of concrete after such an exposure are of great importance in terms of the serviceability of buildings. Unravelling the heating history of concrete and different cooling regimes is important to forensic research or to determine whether a fire-exposed concrete structure and its components are still structurally sound or not. Assessment of fire-damaged concrete structures usually starts with visual observation of colour change, cracking and spalling. Thus, it is important to know the effect of elevated temperatures on strength retention properties of concrete. This study reports the effect of elevated temperature on the mechanical properties of the concrete specimen obtained by replacing 30% OPC by GGBS and cooled differently under various regimes. In the heating cycle, the specimen were subjected to elevated temperatures ranging from 150 0C to 550 0C, in steps of 100 0C with a retention period of 1 hour. Then the cooling regimes studied include, furnace cooling, air cooling and sudden cooling. After exposure to elevated temperatures and cooled differently, the weight loss, residual compressive and split tensile strengths retention characteristics are studied. Test results indicated that weight and both strengths significantly reduce with an increase in temperature and are strongly dependent on cooling regimes adopted. Index Terms: Elevated temperature, Residual compressive strength, Cooling regimes, and Blended concretes

The experimental programme includes strengthening and flexural strength test of 18 simply supported RC beams of 500x100x100 mm. The test results showed an increase in ultimate load for the retrofitted beam when compared to normal control beam and corresponding increase in the value of modulus of rupture. The retrofitted beams with glass fibre using epoxy as binder having 47.32% more strength than the control beams. Area under load-deflection curve gives toughness. Toughness value is found to be more in RC beams retrofitted with banana fibre.
Developing A Prediction Model for Tensile Elastic Modulus of Steel Fiber – Ce...IJRESJOURNAL
ABSTRACT: This paper attempts to develop a prediction model that can be used in line with prescribed laboratory experiments for indirect tensile test such that tensile elastic modulus can be predicted for cement stabilized lateritic soil reinforced with steel fiber using measured properties of the material. The results of the tensile elastic modulus obtained from the Derived Prediction Model almost nearly replicates that obtained from calculations from laboratory experimentation. Results obtained revealed that both the predicted values and calculated values have a linear correlation with an R2 of 96.4%. On this basis the Derived Prediction Model can be said to be valid within the limits of the study.

The document summarizes an experimental study on using carbon fiber reinforced polymer (CFRP) sheets to rehabilitate and strengthen reinforced concrete beams. Twelve beams were fabricated and strengthened with different CFRP configurations. Beams were loaded to different magnitudes prior to strengthening to study the effect of initial loading. Beams were then retrofitted with one or two CFRP layers and reloaded until failure. Results showed shear strength increased significantly with CFRP sheets. Orienting the sheets at 45 degrees was most effective. The literature review discussed previous research on using CFRP to strengthen beams in flexure and shear. Parameters like CFRP amount and configuration affected failure modes and structural performance.

Seismic response of frp strengthened rc frameiaemedu
This document discusses research on strengthening reinforced concrete (RC) frames with fiber-reinforced plastic (FRP). It summarizes previous studies on using FRP to strengthen beams and columns. However, few studies have analyzed FRP-strengthened RC frames as a whole system. The present study uses finite element analysis to model RC frames strengthened with varying FRP thicknesses and investigates their seismic response. Models of 2-bay, 3-story and 3-bay, 5-story frames are analyzed for different crack locations. The results are intended to help develop design criteria for seismic retrofitting of RC frames with FRP.

This slide show describes the vibrations and fatigue vibrations characteristics of laminated composites like glass/epoxy, carbon/epoxy and their hybrids.
IRJET- Study on Hybrid Glass/Carbon Fiber Reinforced Vinyl Ester Polymer Comp...IRJET Journal
This study examines hybrid glass/carbon fiber reinforced vinyl ester polymer composites. Glass fiber and carbon fibers are chosen as reinforcements for their properties, while vinyl ester resin is selected as the polymer matrix. The document provides background on these materials, including that glass fiber is low-cost and isotropic, carbon fiber is very stiff with low density, and vinyl ester resin has high strength and corrosion resistance. Previous research found that hybrid composites can achieve optimized properties by combining different fiber types and that fiber parameters like length, orientation, and diameter influence mechanical characteristics. The goal of this study is to investigate these hybrid composites and how fiber properties affect their mechanics.
Flexural rigidity is a measure of the stiffness of textile fibers and fabrics. It depends on properties of the fibers like the modulus and diameter as well as the structure and properties of the yarns and fabrics. For knitted fabrics, flexural rigidity increases with increasing amounts of stiffer fibers like polybutylene terephthalate. It affects properties like handle, drape, creasing and wear performance. Flexural rigidity is important for applications requiring stiffness like industrial fabrics. It can be experimentally measured using a cantilever bending technique. The flexural rigidity of fabrics depends on parameters like yarn diameter and count, weave structure, and the flexural rigidity of the constituent yarns.
Exposure to elevated temperatures and cooled under different regimes a stud...eSAT Journals
Abstract Fire is one of the most destructive powers to which a building structure can be subjected, often exposing concrete elements to elevated temperatures. The relative properties of concrete after such an exposure are of great importance in terms of the serviceability of buildings. Unravelling the heating history of concrete and different cooling regimes is important to forensic research or to determine whether a fire-exposed concrete structure and its components are still structurally sound or not. Assessment of fire-damaged concrete structures usually starts with visual observation of colour change, cracking and spalling. Thus, it is important to know the effect of elevated temperatures on strength retention properties of concrete. This study reports the effect of elevated temperature on the mechanical properties of the concrete specimen obtained by replacing 30% OPC by GGBS and cooled differently under various regimes. In the heating cycle, the specimen were subjected to elevated temperatures ranging from 150 0C to 550 0C, in steps of 100 0C with a retention period of 1 hour. Then the cooling regimes studied include, furnace cooling, air cooling and sudden cooling. After exposure to elevated temperatures and cooled differently, the weight loss, residual compressive and split tensile strengths retention characteristics are studied. Test results indicated that weight and both strengths significantly reduce with an increase in temperature and are strongly dependent on cooling regimes adopted.

This document summarizes an experimental study on the flexural strengthening of continuous two-span unbonded post-tensioned concrete beams with end-anchored CFRP laminates. Five full-scale beams were tested: one control beam and four beams strengthened with CFRP laminates of varying widths and end anchorage configurations. The study found that CFRP strengthening increased the service load capacity more than the ultimate capacity. Proper end anchorage and installation of the CFRP laminates was important to achieve effective load transfer and prevent premature debonding failures. The strengthened beams exhibited higher stiffness and load capacity compared to the control beam.
USE OF CFRP LAMINATES FOR STRENGTHENING OF REINFORCED CONCRETE CORBELSIAEME Publication
This work consists of fabrication and testing of sixteen reinforced concrete corbels. Fourteen of these corbels have been strengthened or repaired by various plies of Carbon Fiber Reinforced Polymer (CFRP) laminates. The experimental variables considered in the test program include, the CFRP pattern scheme (i.e. location, orientation, and number of layers), bond type (partial warping, full warping, and using CFRP anchors), and damaged ratio. Two modes of failure were observed, debonding and rupture of the CFRP laminates. Significant increase in ultimate capacity ranging from 17% to 71% was registered in the strengthening specimens and from 13% to 65% in repaired specimens.
This document summarizes a study that tested 14 reinforced concrete beams that were initially cracked and then strengthened with various fiber reinforced polymer (FRP) laminate systems. Five strengthening systems using different types of carbon and glass FRP sheets and plates were used. The effects of the strengthening on load capacity, deflection, failure mode, strain, and ductility were examined. It was concluded that vertical FRP sheets around the beam, in addition to longitudinal layers, significantly reduced deflection and increased load capacity. A combination of vertical and horizontal sheets doubled the ultimate load capacity but resulted in brittle failure, requiring a higher safety factor in design.
Carbon Fibers & Carbon Fiber Reinforced Plastics (CFRP) - A Global Market Ove...Industry Experts
Carbon fibers have gained an immense importance in a range of applications in industrial sectors such as wind energy, automotive, civil engineering, pressure vessels as well as in aerospace & military, motorsports and other sporting goods because of their superior characteristics like enhanced stiffness & tensile strength, low weight, improved chemical resistance & temperature tolerance and low thermal expansion. The industries, having the high growth potential for carbon fiber reinforced plastics (CFRP) and intern carbon fibers in the near future include automotive, wind energy, aerospace & defense, offshore oil & gas applications and composite pressure vessels among others.
This document is a master's thesis that models the adhesive interface between steel and carbon fiber reinforced polymer (CFRP) using finite element analysis. The thesis aims to create a simplified finite element (FE) model of a laboratory composite beam test setup using shell elements and spring connectors to model the adhesive interface. The results from the model are compared to analytical calculations and a previous high-detail 3D solid element FE model. The model shows good agreement with theoretical interfacial shear stresses but it is difficult to study normal stresses due to the complex manual extraction process required. The simplified model is easy to create for 2D surfaces but would be complicated for 3D adhesive shapes.
Performance of Concrete at Elevated Temperatures: Utilizing A Blended Ordinar...IOSR Journals
This study aimed at investigating the effect of subjecting concrete, produced with cement being
partially replaced with saw dust ash (SDA) to elevated temperatures. The performance of the test concrete cubes
was done by exposing them to elevated temperatures of 200oC, 400oC, 600oC and 800oC, and allowed to cool
down to room temperature before testing for their properties. Both the physical and thermal properties of the
concrete cubes were determined. The concrete produced by blending cement with 10% SDA with an average
percentage loss of 23.04% retained more of its compressive strength when exposed to the different
temperatures, than concrete produced using only OPC, which has an average percentage loss of 29.11%. It is
also found that, at an elevated temperature of 800oC, concrete fail totally in flexure due to the effect of high
heat on binding elements. The flexural strength of both the control concrete (at 0% OPC replacement) and
OPC/SDA blended concrete (at 10% OPC replacement) decreased as the temperature is increased. The
replacement of OPC by 10% SDA increased the thermal shock resistance of the concrete by 11 cycles than the
0% OPC concrete at the same temperature. The concrete produced with OPC has better thermal conductivity
than the concrete produced by blending OPC with SDA, as a result, the dislodgement of the concrete edges is
relatively lower in the SDA blended cement concrete than in the OPC concrete. The result shows that, blending
OPC with SDA in concrete performed better at elevated temperatures than concrete produced with only OPC.
Therefore, the replacement of OPC with 10% SDA can be applied as a fire resisting bonding material in
concrete.
This document presents a study on polymer modified steel fibre reinforced concrete (PSFC). Steel fibre reinforced concrete (SFC) has better strength and durability than ordinary concrete. Adding a polymer emulsion like styrene butadiene rubber (SBR) to SFC can further improve its properties. The study experimentally determined the flexural and compressive strength of PSFC mixes. It also analyzed the microstructure of PSFC using scanning electron microscopy and mercury intrusion porosimetry to study the effect of SBR on porosity and pore size distribution. The results showed that adding 3-10% SBR increased flexural strength of SFC significantly but could decrease compressive strength. PSFC also had lower porosity and refined pore sizes compared
Behavior of r.c.c. beam with rectangular opening strengthened by cfrp and gfr...eSAT Journals
Abstract
In the construction of multistory buildings the opening in beams are provided for utility ducts and pipes. Providing an opening in
beam develops cracks around the opening due to stress concentration. In this paper the behavior of R.C.C. beam with rectangular
opening strengthened by CFRP and GFRP sheets were studied. This paper presents the behavior of R.C.C. beam with rectangular
opening strengthened by CFRP and GFRP sheets with different techniques. In this experimental study total ten beams were casted,
one beam without opening (i.e. solid beam) and one beam with rectangular post opening and these two considered as a control beams
for comparison. The remaining eight beams were externally strengthened by Carbon fiber reinforced polymer (CFRP) and Glass fiber
reinforced polymer (GFRP) sheets with different strengthening techniques i.e. around the opening, inside the opening, inside and
around the opening and double layer around the opening. These beams were tested under two point loading in the loading frame. The
effect of CFRP and GFRP sheets with different strengthening schemes on such beams were studied interns of initial crack load,
ultimate failure load, cracking pattern and deflection, From the experimental results it is concluded that the ultimate load carrying
capacity of the R.C.C. beam with opening strengthened with GFRP sheets of different schemes were increased in the range of 3.74 to
37.41% and beams strengthened with CFRP sheets increased in the range of 9.35% to 50.50%. Among all these techniques, the
strengthening with CFRP around and inside the opening was found more effective in improving the ultimate load carrying capacity of
beam. This investigation helps the practicing engineers to provide an opening in the beams without reducing its load carrying
capacity.

Behavior of concrete damaged by high temperature exposureand confined with cf...IAEME Publication
This document summarizes an experimental study on the behavior of concrete cylinders damaged by high temperatures and confined with carbon fiber reinforced polymer (CFRP) fabrics. 28 concrete cylinders were fabricated and 22 were exposed to 500°C for 1 hour before being wrapped with 0-3 layers of CFRP. It was found that CFRP wrapping can increase the compressive strength and ductility of both undamaged and heat-damaged concrete cylinders. Strength and ductility increased with more CFRP layers. Failure occurred via sudden rupture of CFRP sheets at mid-height. CFRP confinement allowed restoration of strength in heat-damaged concrete.
This document summarizes research on strengthening reinforced concrete beams using fiber reinforced polymer (FRP) sheets. It discusses how FRP strengthening has become a popular technique worldwide due to advantages like high strength, light weight, corrosion resistance, and easy installation. The document reviews literature on strengthening both simply supported and continuous beams. It outlines different FRP strengthening methods and discusses factors that influence the behavior and failure of strengthened beams, such as surface preparation, adhesive type, and concrete strength. The document also discusses design considerations and challenges for FRP strengthening, as well as disadvantages like lack of design codes and fire risk.
Strengthening structures via external bonding of advanced fibre reinforced polymer (FRP) composite is becoming very
popular worldwide during the past decade because it provides a more economical and technically superior alternative
to the traditional techniques in many situations as it offers high strength, low weight, corrosion resistance, high fatigue
resistance, easy and rapid installation and minimal change in structural geometry. Although many in-situ RC beams
are continuous in construction, there has been very limited research work in the area of FRP strengthening of continuous
beams.
This document discusses fiber reinforced polymer (FRP) composite materials and their use in strengthening structures. It provides definitions of composites and FRP composites. It describes the advantages of composites over traditional materials such as corrosion resistance, high strength to weight ratio, and design flexibility. The key constituents of composites are described as the resin, reinforcements, and fillers. Various resin and fiber types are discussed and compared in terms of their properties. The document outlines different manufacturing processes and how composites can be tailored for specific structural applications by adjusting variables like fiber type, orientation, and resin selection.
The document discusses carbocrete, which is concrete reinforced with carbon fibers. It provides a history of carbon fibers dating back to Thomas Edison's use in light bulbs in the late 1800s. The manufacturing process of carbon fibers is explained involving stretching and heating fibers to increase strength. Carbocrete has higher strength than steel but is lighter. Testing shows improved flexural and tensile strength over concrete. Applications include buildings, bridges, and unique 3D printed structures. While expensive initially, carbocrete provides durability and reduced long term costs.
Fiber-reinforced polymer (FRP) composites are typically made of fibers like glass, aramid, or carbon in a polyester or vinyl ester resin matrix. FRP bars are being researched to replace steel reinforcement in concrete as steel is susceptible to corrosion which reduces the lifespan of concrete structures. FRP composites are corrosion resistant, lightweight, and strong. They offer easy construction and handling and have applications in new FRP bridge decks, concrete decks with FRP rebar, and strengthening existing structures. However, FRP composites are still under testing and research as connections are difficult and the fibers cannot be easily bent in the field without losing strength. More design work is needed for this material.
An insight to modern material used in aircraft and automobile known for its low weight and high strength. This gives an understanding of carbon fiber reinforced plastics(CFRP), its properties, applications, processing technologies.
The document discusses various fiber reinforced plastic (FRP) composite manufacturing processes. It defines FRP composites and describes common matrix materials like thermoset and thermoplastic resins. Manufacturing methods covered include hand lay-up, spray-up, resin transfer molding (RTM), filament winding, pultrusion, matched-die molding, and reaction injection molding (RIM). Each process is explained along with associated materials, equipment, advantages, disadvantages and applications.
FRP is a composite material made of a polymer matrix reinforced with fibers or particles. The reinforcing materials improve the strength and elasticity of the polymer. Fiber reinforced plastics specifically use fiber reinforcement. Common fiber types include glass, carbon, and aramid fibers. The properties of the FRP depend on the properties of the fibers and matrix, their relative volumes, fiber length and orientation. FRPs are used in applications requiring high strength, stiffness, stability and resistance to heat, chemicals and abrasion.
Connections are devices used to join structural elements together to safely transfer forces between them. There are different types of connections classified by their means of connection, such as welded, riveted, and bolted, and by the forces transferred, such as truss connections, fully restrained connections, and partially restrained connections. Fully restrained connections provide continuity between structural members and allow over 90% of moment to be transferred to provide greater flexural resistance. Partially restrained connections have less rigidity than fully restrained connections and allow some percentage of moment and full shear to be transferred. Semi-rigid connections provide rigidity between fully restrained and simple connections and transfer approximately 20-90% of moment.

This work consists of preparation and testing of different structural model like cubes, Beams and Columns. They are tested for Compression test, Flexural test and Split tensile Test. The comparison between Laminated and un-laminated Structural Models was made in order to know how much strength gain after testing of these structural models, so by which the rehabilitation of any structure can be done without demolishing it with less weight to strength ratio.
Experimental and numerical study on behavior of externally bonded rc t beams ...IJARIIT
Fiber-reinforced polymer (FRP) application is a very effective way to repair and strengthen structures that have
become structurally weak over their life span. FRP repair systems provide an economically viable alternative to traditional
repair systems and materials. In this study, an experimental investigation on the flexural behavior of RC T-beams
strengthened using glass fiber reinforced polymer (GFRP) sheets are carried out.
Reinforced concrete T beams externally bonded with GFRP sheets were tested to failure using a symmetrical two
point static loading system. Seven RC T-beams were casted for this experimental test. All of them were weak in flexure and
were having same reinforcement detailing. One beam was used as a control beam and six beams were strengthened using
different configurations of glass fiber reinforced polymer (GFRP) sheets. Experimental data on load, deflection and failure
modes of each of the beams were obtained. The effect of different amount and configuration of GFRP on ultimate load
carrying capacity and failure mode of the beams were investigated.
The experimental results show that externally bonded GFRP can increase the flexural capacity of the beam
significantly. In addition, the results indicated that the most effective configuration was the U-wrap GFRP.A series of
comparative studies on deflection between the present experimental data and results from finite element method and IS code
method were made. A future area of research are being outlined.
Behaviour of Glass Fiber Reinforced Polymer Composite in Flexure Shear Streng...ijtsrd
The corrosion of steel reinforcement in concrete reduces the life of structures, causes high repair costs and can endanger the structural integrity of the structure itself. Glass fibre reinforced polymer GFRP offers a number of advantages over steel especially when used in marine and other salt laden environments. GFRP reinforcing bars are gradually finding wider acceptance as a replacement for conventional steel reinforcement as it offers a number of advantages. Technical studies on a number of concrete structures, from five to eight years old and constructed with GFRP reinforcement, have shown that there is no degradation of the GFRP from the alkaline environment. Concrete is very strong in compression but it is extremely weak in tension. To resist the tensile stress, steel reinforcement is provided in concrete. Reinforcement corrosion and structural deterioration in reinforced concrete structures are common, and prompted many researchers to seek alternative materials and rehabilitation techniques. One such material that has been offered as an alternative to mild steel reinforcement is Glass Fibre Reinforced Polymer GFRP bars and flats. For the repair and strengthening of structural concrete members, strengthening with Glass Fibre Reinforced Polymer GFRP plates is an excellent option. The present work is to study the behavior of Shear resistance of the silica coated GFRP stirrups in the shear test zone. A series of studies were conducted using silica coated GFRP stirrups in shear zone. It is observed that beams with silica coated GFRP flats shear reinforcement have shown failure at higher loads than the theoretical failure loads. Further it is observed that GFRP flats as shear reinforcement exhibit fairly good ductility. Er.

Reinforcement of Reinforced Concrete Beams using CFRP and GFRPijtsrd
Concrete, steel and masonry materials are the common materials used for housing, office buildings, bridges, power plant structures and these structures are being deteriorated with age. The deterioration of the structures is due to the design deficiency, materials deficiency, poor workmanship and extreme loads. Most of the investigation reports on strengthening of damaged RC structures are based on patch repairing and using FRP sheets for flexural, shear and compressive strengthening of members. This research work is mainly focused on retrofitting of RC beams using GFRP and CFRP sheets. In this study the flexural behaviour of M 20, 40and M60grade RC beams retrofitted with single, double and triple layers of GFRP sheets is done and all the beams are analysed using ANSYS modelling and compare with the experimental results. From the presence study, it is derived that strengthening of RC beams with GFRP and CFRP sheets can enhance the load carrying capacity of beams and at the same time deflections up to yield stage of loading is increased and further the deflections are reduced up to ultimate stage of loading. The RC beams strengthened with GFRP and CFRP sheets show a marked reduction in crack width at all stages of loading and substantial delay in the formation of first crack.

This document presents an experimental study on the flexural behavior of concrete beams reinforced with glass fiber reinforced polymer (GFRP) bars. Four concrete beams were cast with M30 concrete - two with GFRP as the main reinforcement and steel bars as hangers, and two with GFRP as both the main and hanger reinforcement. Testing of the beams included calculating their flexural strength. The results showed that beams with GFRP reinforcement had higher ductility than comparable steel-reinforced beams. GFRP is a potential alternative to steel due to its corrosion resistance, high tensile strength, and non-magnetic properties. The study provides data on the material properties and flexural behavior of concrete beams reinforced with GFRP

This document reviews 10 articles on carbon fiber reinforced polymer (CFRP) strengthened reinforced concrete beams. The articles studied parameters like CFRP orientation, anchorage techniques, beam dimensions, and fiber direction. Tests showed that CFRP increased beam shear capacity and flexural strength when anchored properly to prevent premature debonding. Larger beams saw less improvement from CFRP sheets due to size effects. Orienting CFRP fibers at 45 degrees perpendicular to cracks optimized shear strengthening.
This document discusses fiber reinforced concrete (FRC) and its durability in marine structures. It provides background on how fibers suppress crack formation in concrete and improve its fracture toughness. The document reviews literature on how the addition of fibers enhances various mechanical properties of concrete. It also discusses considerations for mixing FRC, including how fiber type, volume, and size can impact dispersion. Finally, it presents properties of different fiber materials commonly used to reinforce concrete.

This document summarizes research on retrofitting reinforced concrete beam-column joints using ferrocement, glass fiber reinforced polymer (GFRP), and carbon fiber reinforced polymer (CFRP). It presents the methodology, results, and conclusions of finite element modeling conducted using ANSYS. The modeling analyzed exterior beam-column joints under different retrofitting conditions: without retrofitting, with ferrocement, with GFRP, and with CFRP. The results showed that retrofitted joints had 30% higher load carrying capacity and improved load-deformation behavior compared to unretrofitted joints. Specifically, CFRP retrofitting shifted the failure from the column to the beam, preventing progressive collapse. In conclusion, fiber-reinforced polymer

Review on Structural Performance of Honeycomb Sandwich PanelIRJET Journal
This document summarizes research on the structural performance of honeycomb sandwich panels. It discusses how honeycomb cores provide high strength-to-weight ratios and good mechanical properties. The structural properties of honeycomb structures depend on factors like face sheet thickness, core thickness, cell diameter, cell angle, and foil thickness. Failure by debonding of the face sheets from the core is a major issue. Research has studied how varying the geometric parameters of honeycomb structures affects their static and dynamic performance. Findings show that parameters like face sheet thickness, core thickness, cell diameter, and core material most influence the structural response of honeycomb sandwich panels.

This document describes an experimental study on strengthening reinforced concrete T-beams using basalt fiber reinforced polymer (BFRP) sheets. Seven T-beams were cast, with one control beam and six strengthened beams. The strengthened beams were reinforced with varying configurations and layers of BFRP sheets. Testing was conducted to failure under static loading. The results showed that externally bonded BFRP significantly increased the flexural capacity of the beams. U-wrap configuration with BFRP was found to be the most effective strengthening method. Data on load, deflection, and failure modes was collected and analyzed to evaluate the effect of different BFRP configurations on structural performance.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.
