砌体填充墙RC框架结构抗震性能研究现状及展望

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

砌体填充墙RC框架结构作为建筑工程中最常见的一种结构体系,在中国以及世界范围内都有着广泛的应用.由于填充墙与框架之间复杂的相互作用,到目前为止依然缺乏合理的分析和设计方法来评估结构的抗震性能.在过去的几十年里,国内外许多学者通过试验、有限元模拟等方法对填充墙RC框架结构的相互作用机理和受力性能进行了大量分析,提出了适用于整体抗震分析的各式简化模型.本文从平面内、平面外以及新型填充墙框架结构的抗震性能3个方面论述了砌体填充墙RC框架结构抗震性能的研究现状,介绍了当前的最新研究进展,指出了砌体填充墙RC框架结构抗震研究中尚存的一些问题,并对其发展趋势进行了展望.

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.
