However, in nonlinear static procedure both predetermined target displacement and force distribution pattern are based on a false assumption that the structural behavior and its responses are dominated by the fundamental vibration modes. Therefore, over the past decades, there have been a great number of studies on considering higher mode contribution in nonlinear static results. The Displacement-based Adaptive Pushover Analysis (DAP) is one of the performance assessments tool for improving the accuracy of the obtained results of nonlinear static analysis in estimating the seismic demands of the structures. In this paper, 5 storey L- shaped RC frame is analyzed for seismic Zone IV and designed as per provisions of IS codes. Performance evaluation is carried out by nonlinear static analysis as well as adaptive pushover analysis and results are compared. 1 Introduction Elastic analysis gives a good indication of the elastic capacity of the overall structure and indicates where first yielding occurs. It can’t predict failure mechanisms and account for redistribution of forces Kalpa Publications in Civil Engineering Volume 1, 2017, Pages 132–136 ICRISET2017.
