Comparison of seismic performance of reinforced concrete frame structure and composite frame structure using response spectrum analysis

Abstract

This research is mainly focused on the behaviour of the concrete and composite framed structures when such structural buildings are subjected to special loadings such as seismic loading. To evaluate the forces and failures in such building subjected to seismic forces linear dynamic statistical analysis method - Response spectrum analysis is carried out. This method results us with a complete response of time history at each and every particular joint by showing its displacements and member forces. In this an RC framed structure of M25 grade of concrete with G+7 storey and also a Composite structure of G+6 storey is modelled in ETABS as per Indian Standard Code 1893: 2002 Part(I). The building is situated in Himachal Pradesh with a seismic intensity of zone factor V. The concept of strong column weak beam is adopted here throughout the paper. Response spectrum analysis technique was used with the help of ETABS for both the composite and reinforced concrete structure. The results were explained in detail having the parameters in consideration with the base shear, storey deflection and storey drift are compared for each model.
