Abstract

Pushover analysis is being extensively used for design and performance evaluation of structures under seismic\nloads. Generation of pushover curve from the analysis of RC structures involves a tremendous amount of computational\nefforts and analysis results are very sensitive to techniques employed for geometric and material modelling. This analytical\ninvestigation presents the influence of variation in materials strengths, effective cover to reinforcement variations and\nsequence of plastic hinge formations on pushover analysis results in performance evaluation of earthquake resistant design. A\nsingle bay single storey RC frame is considered in the present study.
