为研究半刚性节点框架-钢板剪力墙结构的抗震性能,通过一榀1:3比例单跨3层半刚性节点框架.钢板剪力墙的拟静力试验,研究了半刚性框架与墙体的相互影响,探究了结构的破坏顺序和破坏模式,分析了结构的承载力,刚度,耗能能力等抗震性能指标.试验结果表明:该结构具有良好的耗能能力,半刚性节点框架和墙板协同工作良好,结构的破坏顺序为内嵌钢板屈曲、屈服-边缘构件屈服-内嵌钢板撕裂-边缘构件屈曲-节点转动-边缘构件弯扭失稳、节点塑性破坏.
In order to study the seismic behavior in the structural system of the semi-rigid connection steel frame with steel plate shear walls, a one-third scale, one-bay, three-story experimental specimen of semi-rigid connection steel frame with steel plate shear walls were tested under the quasi-static to determine some seismic properties, including failure mode, the hysteretic behavior, ductility and energy dissipation. The results show that the specimen exhibited excellent ductility, energy dissipation capacity and great safety margin; the stiffness degradation of the joints was not serious; the requirement of ductility and stress was distinctly lowered by arranging infill panels; the cooperative work between the frame and the steel plate shear wall was well. The failure sequence of the structure was infill plate buckling, then yield, column yield, infill plate tearing, column buckling, connection rotation, column flexural torsional buckling and plastic collapse of the connection.
