AbstractEngineering structures are very difficult to analyze for their dynamic or vibration behavior since they are very complex. In the last couple of decades alone in India, with the incidental loss of life and property witnessed due to failure of structures caused by earthquakes, now attention is given to neglect the adequacy of strength in RC framed structures to resist strong ground motions. As we know that in the present scenario, buildings with shear walls are gaining more popularity than buildings without the shear wall in earthquake-prone areas mainly under zones III, IV and V due to their capability to the resistance during earthquake. In this paper, 7 storey’s RCC framed structure is considered for the seismic analysis which is located in zone III is considered the analysis using equivalent static analysis method. Six models have considered for the analysis out of which one is bare frame model i.e without shear wall and remaining five models are structures with column support shear wall at various positions is considered. Initially, shear walls are used in reinforced concrete buildings to resist wind force. Since building with shear wall gives excellent performance even under seismic force, shear walls are extensively used for all earthquake resistance design. The shear wall imparts lateral stiffness to the system and also carries the gravity load. When design for wind loading, the location of shear wall in building plan does not play important role. In case of Seismic loading, location of shear walls plays a critical role. Under wind loading, a fully elastic response is expected, while during strong earthquake significant inelastic deformations are anticipated. Hence, in this paper, Column support shear walls are placed at different locations in RC frames of G+6 Storey building and analyzed for seismic action and also subjected to static pushover analysis. The modeling and analysis are done using Staad Pro. An attempt is made to study and compare the seismic parameters such as storey displacement, storey drift, storey shear and story stiffness by equivalent static analysis method. This paper aims to find the optimum location of shear walls which can be determined with the help of seismic performance parameters. The torsional effects in a building can be minimized by proper location of vertical resisting elements and mass distribution. Multi-storied RCC building with shear walls is now becoming popular as an alternative structural form for resisting the earthquake force.
