Dynamic behavior of multi-story concrete buildings based on non-linear pushover & time history analyses

Abstract

In many countries and regions in the world, earthquakes are one of the most common natural disasters, which affect both human life and property. To avoid negative effects of earthquake, the nonlinear response of structures under dynamic loading should be accurately modeled to investigate their actual behavior under earthquake loading to ensure safe and sound design. To yield proper results, accurate representative structural models should be developed for the elements resisting lateral loading and representative ground motions pertaining to the site should be employed. Then relating such response to that of elastic behavior should be conducted to correlate response modification factors in design codes with actual response. The main objective of the research is to investigate the effect of basements existence and considering soil pressure on retaining walls on the seismic response modification factor for reinforced concrete structures, based on ABAQUS software analysis results using pushover analysis and time history analysis. For this purpose, experimental results of individually tested RC structures are used in order to verify modeling technique to be adopted.
