摘要：楼板平面内刚度对整体结构抗震性能有着重要影响,为研究带现浇混凝土楼板的框架-剪力墙组合结构体系的抗震性能,对一个3层2跨缩尺比例为1/4的框架-剪力墙组合结构进行了等效单自由度拟动力试验研究,观察该结构在地震作用下的动力反应,着重分析该框架-剪力墙组合结构在拟动力荷载情况下的破坏机制、耗能性能及变形恢复能力,从而掌握该框架-剪力墙组合结构的动力性能,为完善组合结构设计理论提供可靠的试验依据。结果表明,带现浇混凝土楼板的刚性可以保证结构的空间整体性和水平力的有效传递,该组合结构体系具有良好的抗震性能,满足抗震设防烈度为7度的抗震要求。
In-plane stiffness of floors has significant influence on the seismic performance of the entire structure.In this paper,seismic behavior of a frame-shear wall structure system with cast-in-place floor is studied.An equivalent single degree of freedom pseudo-dynamic test is conducted on a three-story double-span structure of 1/4 reduced scale with steel frame-shear wall and cast-in-place concrete floor.The dynamic response of this hybrid structure under seismic load is investigated.The failure mechanism,energy dissipation capacity,and deformation recovery properties under pseudodynamic load are also analyzed.The dynamic performance studied herein provides a reliable experimental basis for improving the design theory of hybrid structures.The results show the rigidity of cast-in-place floor can ensure the integrity of the structure as well as the effective transfer of horizontal force.Overall the design of this hybrid structure satisfies the seismic requirement for 7 degree earthquake intensity.
