摘　　要：本文利用FW-EPA程序分别完成了对三个带小跨高比综合斜筋连梁和普通配筋连梁,高度分别为24层和30层的框架-剪力墙,结构在8度0.2 g和0.3 g地区罕遇地震作用下的动力非线性反应分析,判明了高层剪力墙类结构的位移反应和塑性铰分布特征。同时通过与已有框架梁延性需求的对比,结合对程序计算各连梁延性的统计分析,得出了小跨高比连梁的位移延性需求。The non-linear dynamic response analysis of 24 floors and 30 floors frame-shear wall with syntheses diagonally coupling beams and conventionally coupling beams at 8 seismic grade 0.2 g and 0.3 g area under the rare earthquake was completed by FW-EPA program.The displacement reaction and distribution of plastic hinges character of tall shear wall structure were ascertained.Meanwhile,through comparison with ductility demand of frame beams and combination with statistical analysis of coupling beams ductility computed by the program,the displacement ductility demand of small span to depth coupling beam was summarized.
