Effect of Earthquake on Multistoried Building Resting on Sloping Ground with and without bracing

ABSTRACT As population is going to be increase and due to rapid urbanization of country, India, the buildings are now constructed on hills known as Step back building. But the behavior of buildings on hills or on slopes is different from the buildings on plain ground. This causes irregularity in vertical configuration of building and thus more vulnerable during earthquake. Because of these irregularities as a result of different column height, produces short column effect during seismic action. But to resist these earthquake forces and to improve the stability of building, lateral force resisting members, bracings can be effectively used. In this paper, building configuration resting (Step back building) on slope of 100 without bracings and with bracing having three different height as 10 Storey, 8 Storey and 6 storey is studied. For this, building of symmetrical plan is analyzed by using structural software STAAD v8i using response spectrum method. Analysis gives the result in terms of parameters as storey drift, base shear and fundamental time period. And conclude with effective building configuration with bracing Keywords: ab Step back building, bracings, response spectrum method.
