摘　　要：为了研究不同肢厚比下的框支短肢剪力墙加腋梁式转换结构的力学性能,分别将一榀的不同肢厚比的框支短肢剪力墙加腋梁式结构的模型作为研究对象,对其模拟进行竖向荷载和水平低周反复荷载的加载方式,对结构的滞回曲线、骨架曲线、屈服荷载、极限荷载、延性、破坏形态等进行分析。分析表明:(1)结构的抗震性能受到剪力墙肢厚比影响,并且当肢厚比在合理范围内变化时(增大),抗震性能有所提高;(2)当剪力墙的肢厚比过大或过小时,也会给结构带来许多不利的影响。The haunched beam transfer floor structures of frame-supported short-leg shearwall with different legthickness ratio were simulated under vertical loading and horizontal cyclic loading to study the impact of different leg-thickness ratio on the mechanical propertise and to analyze the hysteretic curves,skeleton curves,yield load,ultimate load,ductility and failure characteristics. The analysis results show that seismic performance of the structures are influenced by leg-thickness ratio and the seismic performance will improve when leg-thickness ratio of shear wall increase within a rational range. However,the structure will show other kinds of problem when legthickness ratio is too big or small.
