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.

In the last ten years or a little more, CFRP strips and fabrics have been successfully externally bonded to rehabilitate the concrete structures. Most of the previous research focused on the use of CFRP as an enhanced material to improve flexural, shear, ductility and ductility behaviour and confinement of concrete structural members, while limited attention was paid to the investigation of strengthened reinforced concrete (RC) members against torsion, particularly continuous concrete beams. This study aims to detect experimentally the CFRP strengthening technique for continuous RC beams exposed to pure torsion. The experimental program includes investigation of two groups of beams; the first group was composed of twelve un-strengthened beam specimens and the second one includes a total of twelve strengthened beam specimens; all were experienced under pure torsion. Factors considered in the testing program included the effects of concrete compressive strength and the angel of a twist. The angle of twist at each level of force applications, torque at first crack, ultimate torque was to be in comparison with for control and strengthened beams. The outcomes of the tests indicated that all beams wrapped with CFRP fabrics resulted in improvement in tensional resistance as compared with the reference specimens.

were tested to failure using a symmetrical two point concentrated static loading system. Two sets of beams were casted
for this experimental test program. In SET I three beams weak in flexure were casted, out of which one is controlled
beam and other two beams were strengthened using continuous glass fiber reinforced polymer (GFRP) sheets in flexure.
In SET II three beams weak in shear were casted, out of which one is the controlled beam and other two beams were
strengthened using continuous glass fiber reinforced polymer (GFRP) sheets in shear. The strengthening of the beams
is done with different amount and configuration of GFRP sheets.

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. In the present study an experimental investigation is
carried out to study the behavior of continuous RC beams under static loading. The beams are
strengthened with externally bonded glass fibre reinforced polymer (GFRP) sheets. Different scheme
of strengthening have been employed. The program consists of fourteen continuous (two-span) beams
with overall dimensions equal to (150×200×2300) mm. The beams are grouped into two series
labeled S1 and S2 and each series have different percentage of steel reinforcement. One beam from
each series (S1 and S2) was not strengthened and was considered as a control beam, whereas all
other beams from both the series were strengthened in various patterns with externally bonded GFRP
sheets. The present study examines the responses of RC continuous beams, in terms of failure modes,
enhancement of load capacity and load deflection analysis. The results indicate that the flexural
strength of RC beams can be significantly increased by gluing GFRP sheets to the tension face. In
addition, the epoxy bonded sheets improved the cracking behaviour of the beams by delaying the
formation of visible cracks and reducing crack widths at higher load levels. The experimental results
were validated by using finite element method
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.

Experimental Behavior of RC Beams Strengthened by Externally Bonded CFRP with...IJERDJOURNAL
Abstract:- Carbon fiber-reinforced polymers (CFRP) laminates, or plates, offer very high-strength potential; however, handling of long pieces of these flexible plates can present challenges under field conditions. The development of methods for splicing CFRP plates will enhance the versatility and Practicality of using these materials in field applications. This paper studies the efficiency of CFRP lap splice in externally bonded CFRP flexural strengthened reinforced concrete beams. Seven half-scale beams with different conditions were tested in two-point bending until failure. Two groups were tested; the first one includes control specimens: the first without CFRP strengthening, the second strengthened with full length and without splice, and the third with cutoff at middle of the beam. All specimens in the second group having cut-off at the middle and with lap splice lengths equal 300, 450, 600, 900 mm. respectively on each side of the cut-off. The study illustrates the effect of confinement on the first crack load, failure load, mid-span deflection, and strain in both reinforcement and CFRP. The failure load was also predicted analytically by CEB-FIP (1993), adopting the traditional sectional analysis for strain compatibility. Instead of strain measuring, three accurate bond-slip models are used to provide accurate prediction for the contribution of CFRP in the flexural capacity of the strengthened beam since all strengthened beams are failed by interfacial debonding of CFRP.

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.

Experimental Study of Maintenance and Treatment of R.C.C. Building by Fiber R...ijtsrd
Fiber Reinforced Polymer FRP as an external reinforcement is used extensively to deal with the strength requirements related to flexure and shear in structural systems. But the strengthening of members subjected to torsion is explored only recently. Torsion failure is an undesirable brittle form of failure which should be avoided specially in the earthquake prone areas. In the present work, the behavior and performance of rectangular reinforced concrete beams strengthened with externally bonded Fiber Reinforced Polymer FRP fabrics subjected to combined flexure and torsion is studied experimentally. Three sets of concrete cylinders were tested for their ultimate strengths. In SET I three concrete cylindersF1 Without wrap FRP, F2 Single wrap FRP, F3 Double wrap FRP F1, F2 and F3 are tested. In SET II three concrete cylinders S1Without wrap FRP, S2 Single wrap FRP, S3 Double wrap FRP S1, S2 and S3 are tested. In SETIII three concrete cylinders R1 Without wrap FRP, R2 Single wrap FRP, R3 Double wrap FRP R1, R2 and R3 are tested. The concrete cylinders F1, S1 and R1 were taken as the control concrete cylinders. Abdul Quadir Khan | Dr. Shubha Agrawal "Experimental Study of Maintenance and Treatment of R.C.C.

This paper deals with the experimental study on the variation in the load carrying capacity between concrete filled GFRP box beams of size 1200x150x200 mm is predicted by varying thickness of GFRP box beams as 4mm, 6mm and the concrete strength as M40. The material properties of cement, fine aggregate and coarse aggregate would be found out. The compressive strength of concrete cube would be found out to confirm the strength – grade 40. Study results showed that in addition to many advantages due to its formation, the Box Beam showed superior physical and mechanical properties. It was found that the flexural strength and fracture toughness values of Composite beams significantly increased stiffness when compared to reference values. Flexural two point load would be applied on the box beams filled with plain concrete. The experimental test was performed to find the flexural strength, load carrying capacity, deflection, load deflection relationship, load strain relationship and stiffness ratio for various thickness of box beams. The analytical Study was performed by using ANSYS to evaluate the deformation of the specimen. The experimental study of beams showed that the box beam having higher thickness will increase the load carrying capacity and stiffness and also decrease the deflection. In ANSYS by varying both thickness of GFRP box as well as grade of concrete is analysed. The proposed finite element model shows increased resistance to deformation when concrete is used as infill material and the deformation decreases when the grade of concrete and thickness of box beam increases
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
