Stability Analysis of Bottom Double Height Soft-Storey in a Multi-Storyed Satellite Bus-Stop Having Top Soft-Storey and Moment Transfer

Popularity of High-Rise structures of rigid frame system are increasing day by day to accommodate growing people in metropolitan city and to construct the structures without any special structural component and Masonry infills are normally considered as non-structural elements and their stiffness contributions are generally ignored in practice. But they affect both the structural and non-structural performance of the RC buildings during earthquakes. RC frame building with open first storey is known as soft storey, which performs poorly during strong earthquake shaking. A similar soft storey effect can also appear at top storey level if a storey used as a service storey. Hence a combination of two structural system components i.e. Rigid frames and RC shear walls leads to a highly efficient system in which shear wall resist the majority of the lateral loads and the frame supports majority of the gravity loads. To study the effect of P-delta, masonry infill and different soft storey level and moment transfer beams, 10 models of R C framed building were analyzed with two types of shear wall when subjected to earthquake loading. Analysis is done by using Etab 2015 software. The results of bare frame and other building models have been compared, it is observed that model with H and L shape shear wall are showing efficient performance and hence reducing the effect of soft storey and also reducing the effect of water pressure in the top soft storey.
