Progress and prospect of seismic performance of masonry-infilled RC frames

Abstract:

The infilled RC frame, one of the most common structural systems, is applied widely, but there is no rational method for analysis and design to evaluate the seismic-resistant ability due to the complicated interaction between the frames and walls. Many studies on the interaction between frames and walls and the performance of infilled RC frames were performed based on the experimental study and finite element analysis, and a variety of simplified models were proposed in the past few decades, which are capable for the overall seismic response analysis. The research status of seismic performance of infilled RC frames was discussed from the following aspects: in-plane behavior, out-of-plane stability, and seismic retrofitted infilled RC frames. The latest research progress is presented, the existing problems are pointed out, and the research trend is prospected.
