Seismic Analysis of RCC Building with Different Shape of Shear Wall and Without Shear Wall

Abstract

Shear walls are earthquake-resistant structural components used in structures at different locations to resist lateral loads. Shear walls possess large in-plane stiffness that aids in the resistance of lateral loads. In this study, dynamic analysis was carried out on a (B+G+26) storey building and the outcome is studied for varying locations of shear walls. The models considered have been analysed and modelled using FEM integrated software ETABS wherein the models are assumed to be present in the seismic zone IV of INDIA as per IS1893-2016. The models are regular in plan and are assumed to be on type -II (i.e., medium soil). The observations made post analysis through the response spectrum method conclude that a regular structure with uniformly placed shear walls at the centre performs better in comparison to structures without shear walls or structures with other positions of shear walls. The result parameters such as storey drift, storey displacement, storey stiffness, time period and base reactions of the models are compared.
