Abstract
Due to a lack of space, population, and aesthetic and functional needs, multi-story structures in metropolitan areas are now obliged to include column-free space. Buildings with one or more storeys are equipped with floating columns for this purpose. The building of these floating columns is extremely hazardous in earthquake zones. The earthquake forces that emerge at different levels of a building must be carried down the shortest path along the height to the ground. The building's performance suffers as a result of any deviation or discontinuity in this load transfer line. The object of the present work is to study the behaviour of multistorey buildings having floating columns under seismic forces and observe the effect of shear wall in the same building. For this purpose three cases of multi-storey buildings are considered having 6 storey, 9 storey and 12 storey. All the three cases are considered having floating columns provided with different shapes of shear walls and without shear wall, and analyzed for zone V by using software Staad.Pro with static and dynamic analysis methods. Observation shows that the provision of floating columns is advantageous but is a risky factor and increases the vulnerability of the building. From the results it is observed that by the use of shear walls storey drift and lateral displacement values reduces in all the models. For this validation of results is also carried out.
