Influence of opening in infill on R factor of RC infilled frame structures

Abstract

This paper is concerned with study of effect of opening in infill on RC framed structures. Reinforced concrete buildings with masonry infill walls have been widely constructed for commercial, industrial, buildings. In this paper presents the results of analytical program showing behavior of frames with different masonry infill i.e semi-interlocked masonry & Unreinforced masonry. The effect of infill opening on seismic response of frame buildings were evaluated. A nonlinear static analysis has been carried out on different model frames by using finite element analysis software, seismostrct. The results obtained show that calculation of response reduction factor of RC infilled frames with & without opening infill.
