Abstract

In the paper a nonlinear static analysis of irregular structures subjected to monotonically increasing horizontal loading (pushover analysis) is presented. The method is based on an extension of the pseudo three dimensional mathematical model of the structure into the nonlinear range. By step by step analysis an approximate relationship between the global base shear and top displacement is computed. During the analysis the development of plastic hinges throughout the building can be monitored. In the present study, the behaviour of G+20 storied R.C frame buildings (H shape in plan, with and without L shaped column) subjected to earthquake, located in seismic zone III is discussed briefly using ETABS software. Gravity loads and laterals loads as per IS 1893-2002 are applied on the structure and it is designed using IS 456. Displacement control pushover analysis is carried out.
