【摘要】 联肢剪力墙是高层建筑结构中广泛采用的抗侧力结构体系,而连梁是联肢剪力墙结构中重要的耗能构件。然而,不论是传统的钢筋混凝土连梁还是钢连梁或型钢混凝土组合连梁破坏后修复或更换都比较困难,代价昂贵。近年来,国内外的部分学者开始研究可更换连梁,使连梁在受损后易于修复或更换,减小连梁修复费用。本文首先提出了可更换连梁的定义和分类,然后对目前国内外可更换连梁的研究现状进行了比较全面的总结,特别是介绍了2012年9月第15届世界地震工程会议上展示的相关研究成果,最后对可更换连梁的研究未来做了展望。更多还原

【Abstract】 Coupled shear wall structures are often employed as efficient lateral-force-resisting-systems in tall buildings,and the coupling beams are often used as important members to dissipate the seismic energy.However,after the traditional RC coupling beams,steel coupling beams or steel-concrete composite coupling beams damaged in the earthquakes are difficult and cost to berepaired or replaceed.In recent years,some scholars began to study the replaceable coupling beam,which is easy and cheap to be replaced afler earthquake event.In this study,firstly the definition and classification of replaceable coupling beam are proposed,and then a special and detailed summary on replaceable coupling beam is introduced,especially for related research results shown at 15 WCEE in September 2012.Finally,the prospect of research on replaceable coupling beams is assessed.更多还原
