Dynamic Analysis of RCC Framed Structure using different Shear Wall Locations

Abstract

In the design of the multi-storey building, the whole building should effectively resist lateral loads such as earthquakes and wind loads acting on them. The main reason for the horizontal movement and the development of high stresses in buildings is these lateral loads. Therefore, buildings should have more strength and stiffness to resist lateral loads acting on them. To have both these, one of the most efficient structural systems is the shear wall structures. In the present study, a 13 storey RCC structure with different shear wall locations is analyzed and designed by IS: 456-2000 using ETABS software. The equivalent static lateral force method for zone-IV, soil type medium as per IS 1893:2016, part-1, and time history analysis using the Bhuj earthquake data are considered for seismic analysis. The following response quantities, such as mode period, storey displacement, and base shear using equivalent static lateral force method, and time history analysis results are tabulated and discussed. Proper location of the shear wall gives better lateral load resisting capacity in RCC buildings. These shear walls need to be provided at suitable locations to increase the stiffness and reduce the building displacement due to earthquakes.
