IRJET- Effective Location of Shear Wall, its Significance and Displacement An...IRJET Journal
This document discusses the effective location of shear walls in buildings and analyzes their impact on lateral displacement. It summarizes the results of analyzing a typical 11-story building model in different configurations: without shear walls, with shear walls only at the corners, and with shear walls around the entire perimeter. The analysis found that lateral displacement decreased significantly when shear walls were included. Specifically, total displacement was reduced by over 50% when shear walls were placed around the entire perimeter compared to no shear walls. Properly located shear walls can effectively resist earthquake forces and reduce lateral sway, demonstrating the importance of optimizing shear wall placement in high-rise building design.

IRJET-Effective Location Of Shear Walls and Bracings for Multistoried BuildingIRJET Journal
This document analyzes the effectiveness of different structural configurations for resisting lateral loads in a 10-story building subject to seismic activity. Two structural models are considered: a normal building frame and a dual system with shear walls and bracings placed at the building corners. Both models are analyzed using time history analysis in STAAD-Pro. Results show that the dual system experiences significantly less lateral deflection, with displacements reduced by 86-89% compared to the normal frame building. Additionally, the dual system sees only minor reductions in maximum shear force and bending moment compared to the normal frame building. Therefore, the dual system with corner shear walls and bracings provides greatly enhanced seismic performance over a normal framed building.
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.

The document compares the effect of seismic waves on multistoried buildings with and without shear walls and flanged concrete columns. Three 10-story building models are analyzed using STAAD Pro: Model 1 without seismic resisting structures, Model 2 with concentrically located shear walls along the exterior, and Model 3 with flanged concrete columns along the exterior. Model 2 and 3 experience approximately 10% less lateral force and base shear compared to Model 1. Introducing shear walls or flanged columns improves seismic performance by increasing stiffness and reducing displacements, stresses, and forces in the building. While shear walls provide the greatest stability, flanged columns also enhance seismic resistance and may be more economical for some applications.

The document compares the seismic response of a 10-story building modeled with three different configurations: a bare frame, a frame with masonry infill walls modeled as equivalent diagonal struts, and a frame with friction dampers. Non-linear time history analysis was performed using the EL Centro earthquake record. The addition of masonry infills increased the lateral stiffness and decreased displacements and column moments but also increased base shear and accelerations. The use of friction dampers effectively dissipated energy and reduced the structural response compared to the bare frame, without increasing other demands. Analysis results for story acceleration, displacement, column moment, and base shear are presented for each model.
Seismic evaluation of rc frame with brick masonry infill wallseSAT Journals
Abstract
Infill panels are widely used as partition walls as well as external walls of the building to fill the gap between RC frames. Non-structural member may provide considerable stiffness to the building and hence may improve the performance of the RC building during ground motions. But In most of the cases, the ignorance of this property of masonry in designing of the RC frame may get an unsafe design. There are two methods are used to determine the effect of ground motion. The effect of ground motion on RC frame building has been carried out by considering with and without the stiffness of infill wall. A comparative study is carried out with RC building using Equivalent Lateral Force method and Response Spectrum method. The masonry infill has been modeled as an equivalent diagonal strut element using Hendry formula. Pushover analysis is carried out on bare frame and frame with infill wall. The model has been generated using STAAD Pro and results obtained from the analysis are compared in terms of strength and stiffness with bare frame.

Influence of Modeling Masonry Infill on Seismic Performance of Multi-Storeyed...ijsrd.com
Masonry infilled RC frames are the most common type of structures used for multi-storeyed constructions in the developing countries, even in those which are located in seismically active regions also. Masonry infill walls are mainly used to increase the stiffness and strength of R C framed buildings. R C framed building with open first storey is known as soft storey, which performs poorly during earthquakes. A similar soft storey effect can also appear top storey level if it is used as service storey. The soft storey located in the upper part of the multistorey building does not significantly affect. To observe the effect of masonry infill panel, it is modeled as an equivalent double diagonal strut. In this study 7 models are taken were analyzed with two different techniques of modelling of masonry infill wall with L type of shear wall when subjected to earthquake loading. The results of masonry infill show more stiffness than the strut modeling technique. It is observed that, providing infill wall and shear wall improves earthquake resistant behavior of the structure and also the effect of water pressure, an attempt is made to develop relationship between strength and stiffness ratios for linear trend line.

Abstract
Earthquakes are one of the most life threatening, environmental hazardous and destructive natural phenomenons that causes
shaking of ground. This result in damage to the structures, hence we need to design the buildings to withstand these earthquakes
which may occur at least once in the life time of the structure. Structures possess less stiffness and strength in case of irregular
configured frames; to enhance this, lateral load resisting systems are introduced into the frames. In this study, G+5 storey
building model has been analyzed considering different types of vertical geometric irregularities and steel bracings using
pushover analysis with the help of ETABS 9.7 software. Addition of X type brace, V type Brace and Inverted V/K type brace shows
that use of X-type of bracing is found more suitable to enhance the performance of the irregular buildings.
Key Words: pushover analysis, vertical irregularity, steel bracings, performance point.
