PUSHOVER ANALYSIS OF 15 STOREY STEEL BUILDING USING SAP2000

Abstract

To model the complex behavior of steel building analytically in its non-linear zone is difficult. This has led engineers in the past to rely heavily on empirical formulas, which were derived from numerous experiments for the design of steel structures. For structural design and assessment of steel members, the non-linear analysis has become an important tool. The method can be used to study the behavior of steel structures including force redistribution. This analysis of the nonlinear response of steel structures to be carried out in a routine fashion. It helps in the investigation of the behavior of the structure under different loading conditions, its load deflection behavior and the cracks pattern. In the present study, Pushover analysis to obtain nonlinear response of steel frame using SAP2000 under the specify loading as per given in code has been carried out with the intention to investigate the relative importance of several factors in the non-linear analysis of steel frames.
