Structural members subjected to earthquake load conditions experience stiffness and strength degradation that cannot be taken into account by conventional pushover analyses, which apply monotonic external actions. This paper investigates the possibility of using the cyclic pushover analysis as a tool to assess the seismic response of buildings including cumulative damage by means of cyclic loading protocols. To test the effectiveness of this method of analysis, a sample steel moment resisting frame is designed and its seismic response is determined by both the cyclic pushover analysis and the conventional monotonic pushover analysis.

Abstract
Structural members subjected to earthquake load conditions experience stiffness and strength degradation that cannot be taken into account by conventional pushover analyses, which apply monotonic external actions. This paper investigates the possibility of using the cyclic pushover analysis as a tool to assess the seismic response of buildings including cumulative damage by means of cyclic loading protocols. To test the effectiveness of this method of analysis, a sample steel moment resisting frame is designed and its seismic response is determined by both the cyclic pushover analysis and the conventional monotonic pushover analysis.File in questo prodotto:
