Seismic Response of Multistoried RC Structure with Floating Columns for Different Lateral Load Resisting Systems – A Comparative Study

Abstract

Soft storeys, floating columns, vertical or plan irregularities, and large loads are common features of modern multi-storey buildings. In metropolitan India, these types of construction have grown increasingly common. According to the findings of previous earthquake research, the majority of the RC structures built with such imperfections are very unpleasant in seismically active places. These effects occurred as a result of a variety of factors, including non-uniform mass distribution, stiffness, and strength. This study explains the seismic analysis of a G+10 multi-storied building resting on floating columns with different lateral load resisting systems such as shear wall and bracings at different locations and comparison between them in seismically active areas observing its responses to the lateral stresses being applied to the structure externally in seismic zone III using the software ETABS. All models are subjected to equivalent static and response spectrum analysis, with result specified as seismic factors such base shear, storey displacement, storey drift and storey shear.
