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 order to study the seismic performance of the frame-shear wall composite system with cast-in-place concrete slab, the stiffness of a plane slab has an important influence on the seismic performance of the whole structure. The force-wall composite structure is subjected to an equivalent one-degree-of-freedom pseudo-dynamic test, and the dynamic response of the structure under earthquake action is observed. The failure mechanism of the frame-shear wall composite structure under pseudodynamic loads is analyzed emphatically. And deformation recovery ability to master the dynamic performance of the frame-shear wall composite structure, to provide a reliable experimental basis for improving the design theory of composite structures. The results show that the rigidity of cast - in - place concrete floor can ensure the spatial integrity and horizontal force transmission of the structure effectively. The composite structure has good seismic performance and meets the seismic requirements of seismic fortification intensity of 7 degrees.
