| 摘 要： | 通过1榀两层单跨1∶3比例短端板连接的钢框架内填RC墙结构(简称PSRCW)循环荷载试验研究,介绍了PSRCW结构的破坏形态和破坏过程,分析了结构的滞回性能、刚度退化、延性、耗能、节点转动能力等.试验结果表明:PSRCW结构承载力高,抗侧刚度大,但耗能、变形和延性性能一般.在整个试验过程中,试件刚度退化均匀缓慢.试件中与钢梁相连的抗剪栓钉疲劳断裂后,内填墙转为主对角斜压传力.峰值荷载过后,承载力衰减较快,但仍具备较高的残余承载力,可作为第二道抗震防线.短端板节点具有良好的转动能力和抗拉能力,可避免半刚性节点的受拉破坏. |

| Abstract: | Based on an experimental study of one-bay,two-story partially-restrained steel frame with RC infill walls and flushed end-plate connections(PSRCW) at one-third scale under cyclic lateral loading,the failure pattern and damage process were introduced,and hysteretic behavior,stiffness degradation,deformation and ductility,energy dissipation and rotation capacity of connections were analyzed.The results show that the specimen has large lateral strength and stiffness,moderate ductility and deformation capacity.... |
| Keywords: | flushed end-plate connection steel frame infill wall hysteretic behavior experimental study |
