摘　　要：框支短肢剪力墙结构是短肢墙与框支剪力墙相结合而产生的一种结构形式,由于短肢剪力墙的特性,使得其与框支剪力墙结构有很大的不同。为了研究框支短肢剪力墙转换层结构的弹塑性性能,分别以一榀框支短肢剪力墙斜柱式转换试件和一榀相同尺寸的框支短肢剪力墙梁式转换试件为研究对象,对其中的剪力墙做适当的简化后进行Push-over分析,并将分析结果与低周反复荷载试验得到的试验结果对比分析。分析结果表明:计算结果与试验值有较好的吻合;斜柱式转换层结构具有良好的延性和极限刚度。The frame-supported short-leg shear wall structure is a combination of the short-leg shear wall structure and the frame-supported shear wall structure. According to the specialty of short-leg shear wall, the frame-supported short-leg shear wall structure is quite different from the normal frame-supported shear wall structure in structural forms and load-bearing characteristics. Simplified method was adopted to simulate the short-leg shear wall respectively on the model of inclined column-shaped transfer floor structure of framesupported short-leg shear wall and the model of beam-shaped transfer floor structure of frame-supported short- leg shear wall, and the two models were studied by both cyclic loading test and Push-over analysis. Comparative analysis on the results of Push-over analysis and cyclic loading test shows that the values analyzed from Pushover are similar to the values from experiments; inclined column-shaped transfer floor structure has a good ductility and limit stiffness.
