摘要
针对框支短肢剪力墙斜柱式转换结构的抗震性能,开展了3榀斜柱式转换和1榀梁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。
Three inclined column-shaped transfer floor and one beam transfer floor structures of frame-suppor- ted short-leg shear wall were tested under vertical loading and horizontal cyclic loading to analyze the seismic behaviors of inclined column-shaped transfer floors. The failure patter, bearing capacity, hysteretic character- istics and ductility were analyzed in detail. According to the test results, leg-thickness ratio of the short-leg shear wall has important influences on the transfer beam performance. If the design is reasonable, the inclined column-shaped transfer floor structure has a good ductility and better seismic performances
