四角钢连接框架——薄钢板墙结构抗震性能试验研究

摘要

A one-third scale, one-bay, two-story experimental specimen of four-angle composite steel frame with steel plate shear walls was tested under the low-cyclic reversed loading to determine some seismic properties including failure mode, hysteretic behavior, ductility and energy dissipation. The experimental results show that the ultimate capacity and lateral stiffness of the steel frame with four-angle connections can be increased by setting up steel plate shear walls, the structural system has good ductility and energy dissipation, finally the structure loses its bearing capacity due to flexural and torsional buckling of columns, the research can provide a basis for engineering application and theoretical analysis of the structural system.%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.
