Studying the responsive characteristics of earthquake-resistant reinforced concrete structures using MPA method

Abstract

Currently, many analysis methods were used to investigate the characteristics of the earthquake-resistant reinforced concrete structures, i.e. nonlinear geometric and material behavior factors. A nonlinear response history analysis method is used as an accurate tool to assess the response of concrete structures. The given method, however, needs much volume and time for each calculation, i.e. structural designs, therefore it is hard to realize in practice. To simplify and accurate for the computing schedule, another method, the so-called the nonlinear static procedure, is used as an approximate approach to evaluate the effects of earthquakes on concrete structures. In fact, the horizontal load distribution scheme of the building is induced by various parameters. To overcome those limitations, a huge number of research groups have been working on the given issue to modify the horizontal force distribution diagram by including the effects of other parameters beyond the basic mode. Among those studies, the modal pushover analysis (MPA) method was used to give acceptable outcomes for the conventional static analysis, and it could also be realized for the seismic analysis existing reinforced concrete structures.
