Pushover Analysis of RC Building with Steel Braces

Mohammed Zameer Ahamed J

Abstract


Pushover analysis is a static nonlinear procedure which is a basic nonlinear method to approximately calculate seismic structural deformations. It is a static analysis used to find out the force versus displacement capacity curve, for a whole structure or an element of a structure. This procedure consists of applying lateral load, in a determined pattern to the structure in small percentage increase, that is pushing the modelled structure or structural element and plotting the whole functional shear force and related lateral displacement at each step, until the structure attains collapse condition. In the present study symmetric 12 storey RC structures with different steel bracing configurations are modelled and analysed using SAP 2000 by considering Dead, Live and Seismic Loads (IS 1893-Part-1, 2002) and designed using IS-800.
