Comparative Study of Seismic Analysis of Multi- Story Buildings with Floating Columns on Differential Positions and Floors in ZONE IV and ZONE V

Abstract

Abstract: In urban area nowadays commercial as well as residential buildings on its lower floors require large spaces for banquet hall, malls, parking area and for other amenities. For fulfilling these requirements floating columns are generally provided to gain ample space in building structure. As per IS Code 1893:2016 clause no-7.1. The criteria of providing floating column is prohibited, but there is no limitation and restriction for research work. This study highlights the seismic response of a building and to analyze the structure in which there will be less damages to the structure with the presence of the floating column. This study features the significance of unequivocally perceiving the presence of the drifting section in the examination of building. It deals with the software model which validate with literature studies with RC G+12 building model in seismic zone IV and V with different case studies and floating column is provided in columns exterior, interior and core columns consequently. Time history analysis method for seismic analysis of models, various seismic parameters such as time histor of floor displacement, inter storey drift, base shear, overturning moment are compared to find out the most optimized solution. An Evaluation package of ETABS 2016 has been utilized for analyzing the above Building Structure. To keep away from unfriendly impact of seismic power, substitute measures, including firmness equilibrium of the main story and the story above, are proposed to lessen the abnormality presented by the drifting sections by concentrating on various utilization of appropriate technique.
