Abstract
In recent times, multi-storey buildings in urban cities are required to have column free space due to shortage of space, population and also for aesthetic and functional requirements. For this buildings are provided with floating columns at one or more storey. These floating columns are highly disadvantageous in a building built in seismically active areas. The earthquake forces that are developed at different floor levels in a building need to be carried down along the height to the ground by the shortest path. Deviation or discontinuity in this load transfer path results in poor performance of the building. In the present work is to study the behaviour of G+3 buildings having floating columns. However recent studies based on floating columns, which mostly concentrated on higher seismic zones and very few works is available for lower seismic zones Also to obtain the effects of mass variations and infill walls on behaviour of normal and floating column building, one forth portion of typical floor has been provided with higher mass compare to other portions and different building models were analysed with and without provisions of infill walls. Analytical study based on SAP 2000 version 18, shows that corner provisions floating columns on ground floor is worst case provisions. And base on this results cost comparison between normal building and critical floating column building has been done.
