通过一榀1∶3比例单跨双层的四角钢框架内嵌薄钢板墙模型的低周反复荷载试验,研究了模型的破坏特征,滞回特性,延性及耗能性能等抗震性能。试验结果表明:在四角钢框架内设置薄钢板墙能较大程度提高结构的极限承载力与侧向刚度,整个结构具有较好的延性和耗能能力,结构丧失承载力是由于柱发生弯扭屈曲,研究可为该结构的工程应用和理论研究提供参考。
The seismic performance of the model, including failure characteristics, hysteresis characteristics, ductility and energy dissipation performance, was studied by low-cycle cyclic loading test of a thin-walled steel wall with a 1: 3 ratio single-span double-story four- The results show that the thin steel wall in the four-angle frame can greatly improve the ultimate bearing capacity and lateral stiffness of the structure, and the whole structure has good ductility and energy dissipation capacity. The loss of bearing capacity of the structure is due to the bending of the column Buckling, research can provide reference for engineering application and theoretical research of this structure.
