摘　　要：通过对两榀框支短肢剪力墙斜柱转换结构在竖向荷载及水平低周反复荷载共同作用下的拟静力试验,分析了试件的应力分布状态、破坏形态、荷载传递规律以及转换梁的受力性能和试件的抗震性能。试验结果表明,斜柱式转换结构受力特点类似于一个简单桁架,转换层上层传力梁强度和刚度对转换梁性能有重要的影响,设计合理的框支短肢剪力墙-斜柱转换结构具有较好的延性,可以形成多道抗震防线,从而获得较好的抗震性能。According to the pseudo static tests on two specimens of Transfer floor from inclined column to framed short - leg shear wall, which are subjected to the vertical loads and the horizontal cyclic loads, in this paper the stress distributions, final failure model of the specimens, paths of the load transfer and the mechanical behaviors of the transfer beam are studied in detail, the ductility and energy dissipation of the specimens are also specially studied. The results show that this kind of transfer structure can have good seismic behaviors.
