Seismic Analysis and Positioning of Floating Columns in a Multistorey Building using ETABS

Abstract

Many multi-storey and commercial buildings have been developed with architectural complications in recent years. In seismically active zones, buildings with floating columns offer a substantial danger. The presence of floating columns in the structure, disrupts the weight transfer path, resulting in a change in the behaviour and load transfer of the structure. This paper studies the lateral force analysis of a floating column building with a G+10 story height. The main goals of this project are to investigate how multi-story buildings with floating columns behave when subjected to earthquake excitations, to determine whether a structure built in seismic zone II is safe or unsafe when using a floating column, and to determine the most crucial and best position for a floating column within a G+10 structure. The response spectrum analysis is used to assess construction models, with the assumption that when the structure is finished, it will be subjected to all of the loads in a single stretch. The building models are analyzed with the aid of the CSI ETABS 2018 programme.
