A floating column is supposed to be a vertical member starting from foundation level and transferring the load to the ground. In India many of the buildings are constructed with floating column. Floating columns are adopted in order to provide spacious hall and other amenities. The seismic forces generated at different floor level of the building need to be carried out to the foundation by shortest possible way which may not be the case when floating columns are provided. Providing floating columns may satisfy some of the functional requirements but structural behaviour changes abruptly due to provisions of floating columns. In this study analysis of RC structures with floating column in different seismic zones using ETABS is studied. The building is modelled using ETABS software. The models are G+10 RC buildings whereas, one is regular structure and others are structures with floating columns provided in different stories. In this thesis parameters such as storey displacement, storey shear and storey drift are computed using ETABS and the values extracted are compared with each other.
