Comparative study nonlinear static pushover analysis and displacement based adaptive pushover analysis method

Abstract

A major challenge in performance-based earthquake engineering is to develop simple and practical methods for estimating the capacity level and seismic demand on structures by taking into account their inelastic behaviour instead of complicated nonlinear time history analysis. However, in nonlinear static procedure, both predetermined target displacement and force distribution pattern are based on a false assumption that the structural behaviour and its responses are dominated by the fundamental vibration modes. Displacement-based adaptive pushover analysis (DAP) is one of the performance assessment tools for improving the accuracy of the obtained results of the nonlinear static analysis in estimating the seismic demands of structures. The paper attempts to use DAP method to evaluate the performance of 6, 9, 12 and 15 storey RC moment resisting frame, analysed for seismic Zone V and designed as per provisions of IS codes. It is observed from the study that DAP analysis shows better results compared to static pushover analysis.
