IRJET- Evaluation of R.C. Multi-Storey Building Response under the Effect of ...IRJET Journal
This document evaluates the response of a 12-story reinforced concrete building with and without considering soil-structure interaction (SSI). The building is modeled in ETABS and its raft foundation is modeled in SAFE. Results show that accounting for SSI (modeling the building on flexible soil springs) increases story drift ratios, displacements, and bending moments compared to fixed-base modeling. SSI has an unfavorable effect and should be considered in seismic design for more accurate response evaluation.

EXPERIMENTAL MODELING OF IN FILLED RC FRAMES WITH OPENINGIAEME Publication
Reinforced concrete frames are usually infilled with masonry walls but, in most designs, both the shear strength capacity of these walls and the contribution of the infill panel openings on the shear strength of the infilled frame, especially in critical cases of seismic loading are generally ignored. This paper reports the results of an experimental study of the influence of central openings in the infill on the sway stiffness of reinforced concrete plane frames. A series of 1:4 scaled structural models with opening ratios from 0 to 50 percent in steps of 10 percent were designed, constructed and tested in the study to obtain the load - displacement profiles.
Effect of infill walls on the seismic performance of the multistoried buildingseSAT Journals
Abstract The most commonly used structural system in our country for almost all types of building are multi-storey reinforced concrete frames with masonry infills. Therefore it is essential to understand the seismic behaviour of these structures when subjected to lateral forces. Several research works has been done on the masonry infilled reinforced concrete frames in the past decades. Mortar is used as a binder in normal brick construction in order to create continuous structural form and to bind together the individual units in brickwork. In the present study, analysis has been carried out by considering the increase in height of building from five to ten storied by using finite element software ANSYS 14.5. The seismic analysis of multi-storeyed building frames with infill walls and without infill walls are conducted. 3D analysis will give more realistic values of deflection and stresses. Since this type of study is not feasible in terms of analysis time taken, 2D model was adopted for the present study. A three bay two dimensional building frame is considered with the number of stories varying from 5 storied to 10 storied. The loading applied is as per IS 1893 (Part I): 2002. Equivalent diagonal strut method is adopted for modelling infill walls. The results showed that there is considerable decrease in deflection when infills are used in RC frames.

Study of Vertical Irregularity of Tall RC Structure Under Lateral LoadIRJET Journal
This document summarizes a study on the behavior of tall reinforced concrete (RC) structures with vertical irregularities (setbacks and mass irregularities) under lateral loads. Various 30-story RC building models were analyzed using ETABS 2013 software, including regular, setback, and mass irregular models for Seismic Zones 5 and 2. Parameters like story displacement, drift, stiffness, base shear, and time period were compared. Results showed that structures with setbacks or mass irregularities experienced increased displacements, drifts, and base shears compared to regular structures, with greater effects in Zone 5. Irregular structures are more vulnerable to damage from earthquakes.
1) The document reviews several expressions proposed by researchers to calculate the equivalent width of diagonal struts used to model masonry-infilled reinforced concrete (RC) frames.
2) It applies these expressions to a sample one-bay one-story RC frame and analyzes the results using ABAQUS software to validate the modeling approach.
3) The study finds that the Paulay and Priestley expression, which defines the equivalent strut width as one-fourth the diagonal length of the infill panel, provides an average value that gives a reasonably accurate model for further analysis of RC infilled frames.

IRJET- Effect of Different Column Size on Joint Displacement of BuildingIRJET Journal
This document analyzes the effect of different column sizes on joint displacement in a G+6 building under wind loads. A 7-story building model with column sizes of 500x500mm (Model 1) and 600x600mm (Model 2) was analyzed using STAAD Pro software. The maximum displacement was found to decrease from 17% to 31% in Model 2 compared to Model 1, with greater reduction at lower floors. Increasing column size by 20% thus effectively reduced building displacement under wind loads. Joint displacement was also found to increase with building height and bending moments were highest at the top floor.

The buildings were located in different seismic zones with medium soil. Results showed that steel diagrid structures performed better than CFST diagrid structures, with steel diagrid exhibiting lower storey displacements and drifts. Diagrid structures in general were found to effectively distribute lateral loads and reduce the impact of dynamic loading on high-rise buildings.

This document analyzes the seismic response of 20-story reinforced concrete buildings resting on sloping ground with and without considering soil-structure interaction. Eight structural models are considered including buildings on flat ground and slopes of 10, 20, and 30 degrees, both with and without flexible foundations representing soft, medium, and hard soil types. Response spectrum analysis is used to compare displacement, drift, base shear, and other response parameters. The results show that considering soil-structure interaction leads to increased displacement, drift, and decreased base shear compared to fixed foundation models. Displacement and drift also tend to increase with softer soil types and greater slope angles.

Rates of Soft Ground Tunneling in Vicinity of Existing StructuresIJAEMSJORNAL
Soft ground tunneling in the vicinity of existing structures is a major challenge to tunneling engineers. Tunneling works cause inevitable ground movements that may lead to unrecoverable damages to adjacent structures. Tunneling rates significantly affect such risks. However, a guideline that determines appropriate tunneling rates and accounts for the effects of tunneling on the structures existing in the vicinity is not available. Tunneling records in terms of TBM advance speed (AS), utilization factor (U), and advance rate (AR) for tunnels constructed without causing significant risks on the existing structures are presented in the paper.These records are discussed for different types of existing structures.Ranges of these records for tunneling without causing detrimental effects on different types existing structures are recommended.Useful observations are also made on the variation of these records with the ground type and composition and the precautions to be adopted to mitigate the tunneling risks on existing structures.
Seismic performance of r c buildings on sloping grounds with different types ...eSAT Journals
Abstract
Structure are highly susceptible to serve damages in earthquake scenario, so choosing an appropriate lateral force resisting
bracing systems will have a significant effect on performance of the structure. So this present study is aimed at evaluating and
comparing various types of eccentric steel bracings for 12 storey RC frame building resisting on sloping ground configurations.
For this 5 types of bracing systems like X-Bracing, Diagonal bracing, K- bracing, V-bracing and inverted V bracing are
considered on the outer periphery of the buildings with step back and set back – step back type configurations are modeled and
analyzed. The models are compared for different aspects within the structure, such as the maximum storey displacement, base
shear, storey drift and storey shear, the structure is analyzed for seismic zone V and medium soil condition as per IS 1893:2002
using ETABS software. Results conclude that on sloping ground due to irregularity on ground surface, the structures are more
vulnerable to earthquakes. Hence use of eccentric steel bracing is an effective and economical way to resist earthquake forces,
Inverted V type bracing performs well compared to other bracing types. By using inverted V type bracing in step back buildings
types maximum storey displacement of 70% and storey drift of 66% are obtained. Similarly for setback – step back configuration
maximum storey displacement of 74% and storey drift of 70% are obtained respectively.

Analysis of Tunnel Form Building Retrofitted with CFRP using Finite Element M...ijtsrd
Many regions where have the earthquake risk around the world, many buildings in developing countries are ineffective in front of earthquake forces. Recent years, the fabrics which are strengthening with carbon fiber-reinforced polymer CFRP have become a very common material to strengthen the reinforced concrete buildings. In our country, mostly column jacketing and partition systems are used. They are also followed with steel jacketing and trussed steel joist systems. Reinforcement with composites named FRP fiber-reinforced polymer are getting common slowly by slowly in our country. Since fibers are high-tensile steel, they increase the strength of joist and covering deflection. If it is used in the direction of tensile, it also saves the strength for shearing. In this study,1 mm CFRP hardware is applied to the each covering of a 16-floor reinforced concrete building which is made with tunnel formwork system. In this analysis done with SAP2000 program, increase in the frequency of a reinforced concrete building is observed structure which has less in cycle is appeared. These results show us that CFRP hardwares make and 38 increase in the rigid of structure.

IRJET- Comparative Study of Vertically Irregular Buildings Subjected to S...IRJET Journal
This document presents a comparative study of vertically irregular buildings subjected to seismic loads. Vertically irregular buildings, which have changes in stiffness, vertical geometry, or floating columns, tend to experience more seismic forces and are more likely to fail at points of weakness. The study analyzes regular and irregular reinforced concrete buildings using nonlinear static pushover analysis and response spectrum analysis in Etabs software. Parameters like base shear, roof displacement, hinge formation, and performance point are compared. Results show that vertically irregular buildings experience higher stresses, greater displacement, and reduced performance compared to regular structures. Properly analyzing irregularities is important for seismic design and maintaining stability during earthquakes.
Effects of Providing Shear wall and Bracing to Seismic Performance of Concret...IRJET Journal
This document discusses the effects of providing shear walls and bracing on the seismic performance of concrete buildings through pushover analysis. Three models are considered: ordinary moment resisting frame (OMRF) without lateral resistance, braced moment resisting frame (BMRF) with bracing, and wall moment resisting frame (WMRF) with shear walls.
Pushover analysis is performed on the models using software to obtain base shear, storey displacement, and performance point. Results show that providing shear walls and bracing increases base shear at the performance point, reduces storey displacement and drift, and achieves a higher performance state. Global stiffness is also increased. Plastic hinges form more uniformly across storeys in braced and
1) The document analyzes the seismic response of a reinforced concrete frame structure with a soft ground story using computer modeling and simulation. 2) Three models are analyzed: a bare frame model with no infill walls, a model with an open ground story, and a model with steel bracing added to the ground story. 3) Dynamic analysis shows that adding steel bracing to the ground story significantly increases the structural stiffness and reduces drift, displacement, lateral forces, torsion, and time period compared to the bare frame and open ground story models. The steel bracing model performs best in resisting earthquake effects.
Multistoried buildings should be designed such that they offer sufficient stiffness against
lateral displacement and should have the strength to resist inertial forces imposed by the ground
motion arising from earth quakes. Seismic forces in buildings are greatest at the base of the building.
Hence one of the key factors to be considered in designing seismic resistant buildings is the base
shear. Base shear is an estimate of the maximum expected lateral force that will occur due to seismic
ground motion at the base of a structure. In this manuscript we perform a detailed study of the values
of base shear for bare frame as well as infilled frame multi bay, multistoried structures using Free
Vibration analysis in SAP 2000 as well as pseudostatic analysis presented in I.S. 1893(Part I)-2002
The document proposes research to analyze the seismic performance of reinforced concrete buildings with and without masonry infill panels through dynamic analysis and comparison of methods. The research aims to demonstrate the importance of including infill walls in seismic design by comparing bare frame structures to partially and fully infilled frames using analytical and computer models. The results could help reduce risks of collapsed structures in earthquakes by providing a better understanding of how infill walls affect structural behavior.
IRJET- Impact of Shear Wall to Reduce Torsional Effect for Unsymmetrical R.C....IRJET Journal
This document presents a study on analyzing the torsional effects on symmetrical and unsymmetrical reinforced concrete framed buildings under seismic loading. Time history analysis is performed on 10-storey symmetrical and L-shaped unsymmetrical buildings using MATLAB. The response quantities like base shear, displacement and torsional moment are obtained and compared for bare frame, frame with infill walls and frame with shear walls. The results show that the unsymmetrical bare frame experiences higher base shear, displacement and torsional moment compared to the symmetrical frame. Infill walls and shear walls are found to effectively reduce the torsional effects in the unsymmetrical building by shifting the center of rigidity closer to the center of mass.

This document investigates the influence of flank wear land inclination on orthogonal machining using a slip line field model. It summarizes previous research that has considered both zero and non-zero inclination of the flank wear land with respect to the cutting direction. An experimental study is cited that provides evidence of a non-zero flank wear land inclination. A slip line field model is developed that takes flank wear land inclination as an input. Solutions are obtained for variables that characterize the slip line field using an algorithm. Results show that flank wear land inclination decreases with increasing rake angle and increases cutting and thrust forces and subsurface plastic deformation. Uncut chip thickness also decreases with higher flank wear land inclination. The study verifies that flank wear land inclination influences attributes
Main objective of the executed researches was justification of the location of entry
providing its maintenance in a bearing pressure zone. Researches were carried out for
conditions of the Prokopyevsk and Kiselevsky field of the Kuznetsk coal basin
(Russia). Researches were conducted by a finite element method. When performing
researches the provision entry relative of a regional part of the massif and property of
coal changed. As a result of researches influence of strength of coal and the location
of entry on the stress and strain state of the massif is established and the conclusion is
drawn on need of increase in height of a slice up to 10 m. Recommendations of
increase in height of each subsequent slice at mining of soft coals are also made. The
novelty of work consists in establishment of dependences of the stress and strain state
of the massif on height of the mining slice.
Fracture mechanics based estimation of fatigue life of weldsAvinash B
This document presents an approach for predicting fatigue life in welded joints subjected to multiaxial loading. It assumes crack-like flaws exist after welding, so crack initiation is insignificant. Crack propagation analysis or fracture mechanics are used to determine fatigue limits depending on the cycle regime. A weight function method calculates stress intensity factors for a semi-elliptical surface crack near the weld toe. Finite element analysis determines the through-thickness stress distribution. Combining this information with the Paris law and fracture toughness allows predicting fatigue life in the high-low cycle regimes. Validation with S-N curves from welding standards shows the approach can derive material-specific limits for particular welding processes.
The problem in question is relevant since the process of detonation and
shockwaves collision and recompression of detonation products is a challenging task
in terms of gas dynamics. The paper is aimed at addressing this problem that would
enable to intentionally control the process of transferring energy of explosive to
environment through choosing optimal structure of charge or mode of triggering. The
problem is examined mostly through method for numerical simulation of non-steady
detonation and gas dynamic processes occurring while blast-hole charge is exploded.
An attribute-based pattern of process for transferring energy of explosion products to
environment when blasting charges of different structures and with different
parameters of triggering modes was pre-investigated. The paper describes
mathematical model of calculating parameters of dynamic loads on a blast-hole (hole)
wall when exploding charges of various structures in various triggering modes. The
results of calculating parameters of stress wave generated in rock mass by explosive
charge blast and gas dynamic parameters in powder chamber of a blast-hole (well)
were presented. The obtained coefficients of explosion pulse effect allow to correct
calculations of unit rate of differently-structured charges.
This document discusses seismic retrofitting of buildings. It begins with an introduction to the need for retrofitting structures due to factors like material deterioration over time or damage from earthquakes. The main steps in retrofitting are assessing damage through non-destructive testing and then strengthening the structure. Two case studies of retrofitting projects are described involving a water tank damaged in an earthquake and a commercial building with cracks. For both, non-destructive tests were conducted to evaluate material strength and appropriate retrofitting measures like jacketing columns and beams or adding bracing were implemented to strengthen the structures. Retrofitting can restore durability and seismic resistance without disrupting existing properties.

Global stiffness is also increased. Plastic hinges form more uniformly across storeys in braced and
1) The document analyzes the seismic response of a reinforced concrete frame structure with a soft ground story using computer modeling and simulation. 2) Three models are analyzed: a bare frame model with no infill walls, a model with an open ground story, and a model with steel bracing added to the ground story. 3) Dynamic analysis shows that adding steel bracing to the ground story significantly increases the structural stiffness and reduces drift, displacement, lateral forces, torsion, and time period compared to the bare frame and open ground story models. The steel bracing model performs best in resisting earthquake effects.
Multistoried buildings should be designed such that they offer sufficient stiffness against
lateral displacement and should have the strength to resist inertial forces imposed by the ground
motion arising from earth quakes. Seismic forces in buildings are greatest at the base of the building.
Hence one of the key factors to be considered in designing seismic resistant buildings is the base
shear. Base shear is an estimate of the maximum expected lateral force that will occur due to seismic
ground motion at the base of a structure. In this manuscript we perform a detailed study of the values
of base shear for bare frame as well as infilled frame multi bay, multistoried structures using Free
Vibration analysis in SAP 2000 as well as pseudostatic analysis presented in I.S. 1893(Part I)-2002
The document proposes research to analyze the seismic performance of reinforced concrete buildings with and without masonry infill panels through dynamic analysis and comparison of methods. The research aims to demonstrate the importance of including infill walls in seismic design by comparing bare frame structures to partially and fully infilled frames using analytical and computer models. The results could help reduce risks of collapsed structures in earthquakes by providing a better understanding of how infill walls affect structural behavior.
IRJET- Impact of Shear Wall to Reduce Torsional Effect for Unsymmetrical R.C....IRJET Journal
This document presents a study on analyzing the torsional effects on symmetrical and unsymmetrical reinforced concrete framed buildings under seismic loading. Time history analysis is performed on 10-storey symmetrical and L-shaped unsymmetrical buildings using MATLAB. The response quantities like base shear, displacement and torsional moment are obtained and compared for bare frame, frame with infill walls and frame with shear walls. The results show that the unsymmetrical bare frame experiences higher base shear, displacement and torsional moment compared to the symmetrical frame. Infill walls and shear walls are found to effectively reduce the torsional effects in the unsymmetrical building by shifting the center of rigidity closer to the center of mass.

This document investigates the influence of flank wear land inclination on orthogonal machining using a slip line field model. It summarizes previous research that has considered both zero and non-zero inclination of the flank wear land with respect to the cutting direction. An experimental study is cited that provides evidence of a non-zero flank wear land inclination. A slip line field model is developed that takes flank wear land inclination as an input. Solutions are obtained for variables that characterize the slip line field using an algorithm. Results show that flank wear land inclination decreases with increasing rake angle and increases cutting and thrust forces and subsurface plastic deformation. Uncut chip thickness also decreases with higher flank wear land inclination. The study verifies that flank wear land inclination influences attributes
Main objective of the executed researches was justification of the location of entry
providing its maintenance in a bearing pressure zone. Researches were carried out for
conditions of the Prokopyevsk and Kiselevsky field of the Kuznetsk coal basin
(Russia). Researches were conducted by a finite element method. When performing
researches the provision entry relative of a regional part of the massif and property of
coal changed. As a result of researches influence of strength of coal and the location
of entry on the stress and strain state of the massif is established and the conclusion is
drawn on need of increase in height of a slice up to 10 m. Recommendations of
increase in height of each subsequent slice at mining of soft coals are also made. The
novelty of work consists in establishment of dependences of the stress and strain state
of the massif on height of the mining slice.
Fracture mechanics based estimation of fatigue life of weldsAvinash B
This document presents an approach for predicting fatigue life in welded joints subjected to multiaxial loading. It assumes crack-like flaws exist after welding, so crack initiation is insignificant. Crack propagation analysis or fracture mechanics are used to determine fatigue limits depending on the cycle regime. A weight function method calculates stress intensity factors for a semi-elliptical surface crack near the weld toe. Finite element analysis determines the through-thickness stress distribution. Combining this information with the Paris law and fracture toughness allows predicting fatigue life in the high-low cycle regimes. Validation with S-N curves from welding standards shows the approach can derive material-specific limits for particular welding processes.
The problem in question is relevant since the process of detonation and
shockwaves collision and recompression of detonation products is a challenging task
in terms of gas dynamics. The paper is aimed at addressing this problem that would
enable to intentionally control the process of transferring energy of explosive to
environment through choosing optimal structure of charge or mode of triggering. The
problem is examined mostly through method for numerical simulation of non-steady
detonation and gas dynamic processes occurring while blast-hole charge is exploded.
An attribute-based pattern of process for transferring energy of explosion products to
environment when blasting charges of different structures and with different
parameters of triggering modes was pre-investigated. The paper describes
mathematical model of calculating parameters of dynamic loads on a blast-hole (hole)
wall when exploding charges of various structures in various triggering modes. The
results of calculating parameters of stress wave generated in rock mass by explosive
charge blast and gas dynamic parameters in powder chamber of a blast-hole (well)
were presented. The obtained coefficients of explosion pulse effect allow to correct
calculations of unit rate of differently-structured charges.
This document discusses seismic retrofitting of buildings. It begins with an introduction to the need for retrofitting structures due to factors like material deterioration over time or damage from earthquakes. The main steps in retrofitting are assessing damage through non-destructive testing and then strengthening the structure. Two case studies of retrofitting projects are described involving a water tank damaged in an earthquake and a commercial building with cracks. For both, non-destructive tests were conducted to evaluate material strength and appropriate retrofitting measures like jacketing columns and beams or adding bracing were implemented to strengthen the structures. Retrofitting can restore durability and seismic resistance without disrupting existing properties.

Comparative Study of Ferrocement Panels Under Blast Loading by Finite Element...IRJET Journal
This document analyzes the behavior of ferrocement panels under blast loading using finite element analysis in ANSYS. Ferrocement panels with 2-layer and 3-layer mesh configurations and thicknesses of 18mm and 25mm were modeled and subjected to blast loads at varying standoff distances. The results found that panels with greater thickness and mesh layers experienced less deformation and stress under blast loads. Specifically, the 25mm thick 3-layer panel showed 46% less deformation and 58% less strain compared to the 18mm thick 2-layer panel. Therefore, thicker ferrocement panels with more mesh layers provide better blast resistance and should be used for structures at high risk of explosions.
Comparative Study on Flexural Strength of M-40 Grade with Lapping of BarsIRJET Journal
This document presents a comparative study on the flexural strength of M-40 grade concrete beams with different percentages of lapping (overlapping) of reinforcement bars. Cubes and beams were cast and tested according to Indian standards. The compressive strength of cubes increased with the use of manufactured sand as a replacement for natural sand. Beams with 0%, 25%, 50%, and 100% lapping of bars were tested under two-point loading. Cracking and ultimate loads increased with higher lapping percentages, with 0% lapping exhibiting the highest strength. Higher lapping percentages led to higher deflections at given loads. In conclusion, manufactured sand can be used as a replacement for natural sand in concrete with similar properties. Higher lapping
The paper reveals the issue of improving the quality of rock mass crushing in
quarries of building materials. The analysis of methods for improving the quality of
crushing has been performed. A method to increase the time of impact of explosion
products on a mountain massif by changing charge design has been proposed. The
method was tested and the results of explosions at the quarry of Leningrad region were
presented. The experimental data show: theoretical calculations are consistent with
experimental data and have a slight deviation; the parameters of the rock mass
disruption allow using wheel loaders in the quarry. Yet, the use of new charge designs
enabled improving the quality of crushing, namely, increasing percentage of output of
an average piece of conditioned fraction, therefore, optimizing operation of the mining
entity as a whole.
The Rion Antirion bridge in Greece connects the Peloponnese peninsula to the mainland across the Gulf of Corinth. Its foundations had to withstand severe environmental conditions including weak soils, earthquakes up to magnitude 7.0, and long-term tectonic movements. The innovative foundation concept adopted reinforced the natural ground with steel tubular piles and included a gravel layer between the piles and foundation raft. This provided capacity to resist the large seismic forces while minimizing differential settlement hazards. Extensive site investigations characterized the poor soil properties to ensure compatible design of seismic demand and foundation capacity.

- Under each caisson, 150-200 steel pipe inclusions 2m in diameter were driven into the soil in a 7m grid to reinforce it. A 2.8m thick gravel layer separated the caisson from the inclusions.
- This concept provided capacity design by allowing sliding at the gravel interface during large seismic forces, limiting forces on the super
Drag Analysis of Bottom Hole Assembly with Varying Friction FactorsIRJET Journal
This document analyzes drag forces in a bottom hole assembly (BHA) for an exploratory well by varying friction factors. It summarizes the planned well profile and compares it to the actual drilled well. Drag forces were calculated for different drilling modes and sections of the well using friction factors ranging from 0.2 to 0.4. The results showed that drag forces matched closely between planned and actual profiles when using a friction factor range of 0.2 to 0.3. This suggests this range should be considered when planning offset wells to select appropriate BHA materials.
Impact testing is an effective method to evaluate the fatigue resistance of coatings under cyclic loading conditions. The authors developed an impact testing procedure using a hard carbide ball that repetitively impacts coated specimens. Three HVOF thermal spray coatings on a P91 steel substrate - WC-CoCr, CrC-NiCr, and Ni20Cr - were tested. The WC-CoCr coating showed superior fatigue strength, sustaining impacts without cohesive delamination failure. In contrast, the brittle CrC-NiCr coating developed microcracks leading to total coating removal after 600,000 impacts. The impact testing results provide insight into coating failure mechanisms and guidance for optimizing coated components used in steam turbines.

Influence of geometric and geotechnical characteristics on the behaviour of a...IRJET Journal
This document presents the results of modelling the behavior of deep foundations (piles) subjected to cyclic lateral loads in sand. The modelling was done using PLAXIS 2D software based on the geometric characteristics of the pile and geotechnical properties of the soil. The results show that piles subjected to lateral loads at the head experience horizontal displacement that depends on the pile's geometric shape and soil characteristics. Subjecting the pile to cyclic loads causes progressive mobilization of the soil mass at the surface. The lateral displacement increases over the initial cycles until stabilizing, resulting in irreversible residual displacement due to progressive plasticization of the soil. Cyclic lateral loading has a positive influence on the pile's behavior under cyclic loads due to reversible effects

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.

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.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

out. However, it is very difficult to mining through faults with of greater than seam
displacement therefore faults define a form of mine fields and length of longwall panels.
Besides, with increase displacement of a fault the zone of its influence increases. Decrease in
strength of rock in a zone of influence of faults leads to change of the field of stress. Besides,
upon transition to depth more than 300 m the danger of rock bump increases. During the
mining stress field can increase in a zone of influence of a fault that leads to increase in
danger of rock bump therefore I exist normative documents which define a coal mining order
in dangerous zones at a fault. Questions of safety of underground coal mining remain very
relevant for Russia [9-27]. The majority of fields of Russia are rich with faults therefore
studying of their influence on the stress and strain state of the rock massif is an important
practical task.
2. METHODS
Before carrying out numerical calculation the existing normative documents and works of
other researchers devoted to geomechanical justification of mining operations [28-47] and
influence of faults [48-50] were studied. When carrying out researches the finite element
method was used. The settlement scheme for carrying out researches is submitted in figure 1.
Apparently from the drawing 1 numerical modeling of a condition of the rock massif at a fault
was carried out at arrangement of longwall panel at distance z from fault at mining of flat coal
seam by height m at depth H.
Figure 1. The settlement scheme for numerical simulation
Modeling was carried out with use of the approaches and recommendations stated in
Article [50]. Fault was modelled by usual elements with the lowered strength properties.
The research was carried out in 2 steps. At the 1st stage assessment of the sizes of a
dangerous zone in compliance with scheme 2 and provisions of the normative document was
executed [49]. For the 3 m seam at a depth of 600 m provided that width of a zone of
influence of a fault - 25 m, width of a dangerous zone will be about 70 m. Taking into account
the sizes of a dangerous zone modeling at value z (figure 1) of equal 75 m was executed. At

http://www.iaeme.com/IJCIET/index.asp 846 editor@iaeme.com
the 2nd stage of researches modeling for a mining situation when mining are conducted in a
dangerous zone is executed and size z is 25 m.
3. RESULTS AND DISCUSSION
Issues of studying of distribution of stress at a fault devoted considerable number of works
[48-50], however their analysis allowed to reveal essential differences in ideas of authors of
the nature of the proceeding geomechanical processes. So, typical distribution of the increased
stress in a zone of influence of fault is presented in figure 2 [48].
Figure 2. A stress distribution curve at a fault: A) normal fault; C) reverse fault [48]
Figure 2,A shows a stress distribution curve ahead of a longwall by normal fault and
confirms constancy of concentration of stress in a zone of bearing stress at change of extent of
this zone owing to influence of fault. Too it is observed observed at a reverse fault (figure 2,
B). Thus, existence of fault has no significant effect in the field of stress ahead of a longwall,
and only leads to restriction of distribution of the increased stress at along strike of seam.
However, according to "The instruction for safe mining in the mines mining the coal
seams inclined to rock bump" [49], conditions of conducting mining operations on layers
inclined to rock bump in zones of influence of fault carry to particularly complex. Extent of
dangerous zones in the presence of faults can be determined by the scheme provided on figure
3.
Y - length of a zone of influence of fault, m; l - length of a zone of bearing pressure, m.
Figure 3. The scheme for determination of the sizes of dangerous zones at mining of the seams
inclined to rock bump in zones of influence of fault: A) mining of a first longwall panel; B) mining of
the second longwall panel [49]

Thus, there is an essential contradiction in work [47] and normative document [49] for the
purpose of which permission researches with use of a finite element method were conducted.
As an example of the received results of numerical researches in figure 4 isolines of
vertical stress in the neighborhood of longwall panel at fault are shown. Apparently zones of
the increased stress - bearing pressure, and directly over and under longwall panel – unloading
zones are formed of figure 4 in regional parts of the massif at longwall panel. The zone of
fault is characterized by the low level of stress.
Figure 4. Isolines of vertical stress
For convenience of perception of results the vertical stress curve through contact seam-
roof (figure 5) is constructed. Figure 5,A shows that the maximum of stress is in a zone of
bearing pressure at distance from a regional part of the massif, as a result of transition of its
part to aт extra limit state. The central part of a vertical stress curve within which stress is
absent corresponds to a longwall panel 200 m width.
Figure 5. Vertical stress curve: А) at z=75 m; B) z=25 m
As a result of researches it is established that the difference of sizes of the maximum
stress from fault from similar from the massif does not exceed 6%. Thus, in the modelled
situation (at z=75 m) geological violation has no significant effect on stress of a regional part
of the massif.
5. Numerical Simulation of Rock Massif Stress State at Normal Fault at Underground Longwall Coal Mining
http://www.iaeme.com/IJCIET/index.asp 848 editor@iaeme.com
Apparently from figure 5,B in which vertical stress curve in regional parts of longwall
panel at z=25 m are presented the maximum values of stress in a zone of bearing pressure
from fault for 25% exceed similar from the massif that demonstrates significant influence of
fault on the level of stress.
4. CONCLUSIONS
The location of the longwall panel at fault can lead to decrease in safety and economic
efficiency of underground coal mining. However, considerable removal of the longwall panel
from fault leads to significant growth of losses of coal. Therefore, the choice of location of the
longwall panel at a fault for safety and economic efficiency of production at low losses of
coal is very important goal.
Numerical simulation with use of a finite element method showed a possibility of
quantitative assessment of stress of the massif at fault. The executed researches confirmed
significant influence of fault on stress of the rock massif and need arrangement of entries at
distance from fault which depends on displacement of fault, depth of mining, a zone of
influence of fault, fault type.
The forecast of stress of the massif is of great importance for ensuring safe deep longwall
coal mining.
