  • Abstract

    Paper devoted to numerical investigation of two important factors that influence on seismic resistance of reinforced concrete structures. Aim: The aim of the research is to study the behavior of different plan irregularities of buildings under earthquake influences with taking into account nonbearing infill walls. Materials and Methods: Next analytic methods were used in this research: finite element method and static pushover analysis. Calculations were performed using pushover analysis with Etabs Software. Results: Obtained seismic resistance ratio of regular and irregular shapes with taking into consideration non bearing infill, which helps to develop Ukrainian system of rapid visual assessment of actual seismic resistance of buildings. According to the results of comparison of seven variants of plan shape, it is seen that seismic resistance of models with infill wall have considerably increased compared with bare RC framed (up to two times and more). And also regularity for the considered schemes varies up to 35%.
