填充墙对RC框架结构抗震性能影响研究现状

Research Status of the Masonry Infill Effect on the Seismic Performance of RC Frames

《建筑抗震设计规范》中规定框架结构在地震作用下应形成"强柱弱梁"的延性破坏机制,而各国震害表明,带填充墙的框架结构大多发生了层间机构破坏、短柱破坏等非延性破坏方式,因此填充墙对钢筋混凝土框架结构抗震性能的影响应当受到重视。介绍了实际震害中填充墙框架结构破坏形态,总结了各国规范对填充墙的考虑,归纳分析了填充墙框架的试验、数值分析及计算模型等相应的研究成果,并提出了研究方向。

According to ＂Code of seismic design of buildings＂, ＂strong column-weak beam＂ ductile failurepattern should be formed in RC （reinforced concrete） frames during strong earthquakes. Earthquake damagein different countries indicates that story damage and short column damage appeared in most of RC frames withmasonry infill. Infill influence on the seismic performance of RC frame structures should be paid moreattention. In this paper, the failure patterns of RC frames with masonry infill are introduced. Theconsideration of masonry infill in design code of countries is summarized. The experiments, FEM analysisresults and computational model are induced. The research direction is proposed at last.
