The Wind and Seismic Analysis on Different Heights of Building by Using ETABS

Abstract

High rise buildings become common in the modern growing cities as the height of the building increase for the given width, the building frame becomes more flexible particularly in the case of frames with heights above 15 stories slenderness becomes more and fundamental frequency of the frames becomes less. The wind pressures are fluctuating the nature and this is illustrated by the wind spectrum. In the present project a building with different heights is analyzed for wind as well as for earthquake loads for different load combinations. Considering a building with height of 20m, 30m, 40m, 50m, 60m in worst condition i.e,, in ZONE-II,III,IV and SOIL-3 and analyzed for load combinations 1.2(DL+LL+LATERAL LOAD) in X direction with lateral load resisting systems. Results of displacement, storey shear, moment are compared for load combinations in both static & dynamic analysis. Results are tabulated and a optimum solution is concluded.
