Experimental study for evaluating the seismic performance of rc frame structure with partially infilled by brick masonry

Abstract

The responses of the brick masonry infilled reinforced concrete (RC) frame structures under seismic excitation were quite complex due to highly nonlinear of their composite behavior and interaction between RC frame structure and it brick masonry infill. The presence of the brick masonry infills can greatly improve the seismic performance of RC frame structures by increasing their lateral strength and stiffness, respectively. However, when the RC frame structure is only partially infilled with the brick masonry wall, the responses of the RC frame structure becomes completely different. In this study, a series experimental was conducted to evaluate the seismic performance of RC frame structures with partially infilled by the brick masonry. Three of 1/4 reduce-scaled of RC frame specimens, i.e. a bare RC frame, a fully brick infilled RC frame and a partially brick infilled RC frame has been experientially tested under lateral static reversed cyclic loading. Experimentally results have shown that existence of the partially brick masonry infilled in the RC frame structure play a significant role in damaging of the RC column.
