框支短肢剪力墙转换结构抗震性能试验研究

摘要

针对框支短肢剪力墙转换结构的抗震性能,开展了1榀梁式转换和3榀斜柱式转换试件在竖向荷载和低周水平反复荷载共同作用下的拟静力试验,对其破坏形态、承载力、滞回性能和位移延性等进行了较为系统的研究.研究表明,转换层上部短肢剪力墙肢厚比对转换梁的受力性能有重要影响；设计合理的框支短肢剪力墙斜柱式转换层结构具有较好的延性,能够形成多道抗震防线,进而获得良好的抗震性能.%One beam transfer floor and three inclined column-shaped transfer floor structures of frame-supported short-leg shear wall are tested under vertical loading and horizontal cyclic loading to analyze the influence of leg-thickness ratio on the seismic performance of inclined column-shaped transfer floors.The failure patter,bearing capacity,hysteretic characteristics and ductility are analyzed in detail.The results show that leg-thickness ratio of the short-leg shear wall has important implications to the transfer beam performance; if the design is reasonable,the inclined column-shaped transfer floor structure has a good ductility,multi-channel seismic line of defense and better seismic performance.
