Compartive analysis of G + 9 structure with shear wall at corners, central bays and alternate bays

Abstract

Need of multi-storey buildings are increasing now-a-days because of rapidly growing population. But when natural calamities like earthquakes occur, there will be great loss to these structures, not only in terms of property but also in terms of causalities. In this paper, an attempt is being made to minimize the loss caused by lateral loads during earthquakes. Shear walls are the one of the most commonly used strategies for resisting the lateral loads. But placing a shear wall at every location is not economical. In this paper, comparison is made among multi-storied structure in different seismic zones by placing shear wall at different locations. Four different configurations viz.., a bay Frame without shear wall, a bay Frame with shear walls at corners, a bay Frame with shear walls at central exterior bays and a bay Frame with shear walls at alternate bays. These Frames are analyzed and results are compared in terms of deflection, bending moments and base shear. Based on the results best configuration is suggested. Analysis of these structures are carried out using STAAD. Pro V8i conforming to Indian codes i.e., IS456:2000, IS1893:2002, IS875 (PART1), IS875 (PART2), IS1343.
