Abstract

Now a day's floating columns are used in multi-story buildings in urban India. There are various uses of floating columns such as space for assembly hall, reception lobbies and parking purpose etc. Such features are highly undesirable in building built in seismically active areas. Due to discontinuity in load transfer path result in poor performance of building. In this paper an attempt is made to study the comparison of seismic performance of building with normal building and floating columns building for various seismic zones in case of medium soil. For this purpose Push over analysis is adopted to get performance point and hinge pattern in a multi-storey buildings. To achieve this objective, model of G+7 storey normal building and building with different locations of floating columns are analyzed and the base shear and displacement of multi-storey RCC buildings have been compared. The analysis is being carried out using SAP 2000 software package.
