在对一榀单跨两层半刚接框架-斜加劲钢板剪力墙结构低周反复荷载试验研究的基础上,分析结构框架梁、柱、半刚节点的局部力学性能及整体破坏模式,评价该种结构体系的抗震性能.结果表明:结构具有良好的塑性变形能力、安全储备高;节点刚度退化小,内填钢板的设置缓解了节点区自身的延性要求,半刚框架和墙板协同工作良好;框架柱兼受轴力和弯距共同作用,腹板参与抗剪,应力状态复杂.研究为该种结构体系的工程应用和理论分析提供了依据.
Based on the experimental study on the low-cycle cyclic loading of single-span single-span two-story semi-rigid frame-diagonal stiffened steel plate shear wall structure, the local mechanical properties and overall failure mode of the structural frame beam, column and semi- The results show that the structure has good plastic deformation capacity and high safety reserve. The node stiffness degeneration is small. The filling of steel plate alleviates the ductility requirements of the node area. The semi-rigid frame and the panel work together The frame column is also affected by the axial force and the bending moment, the web is involved in the shear resistance and the stress state is complex.The research provides the basis for engineering application and theoretical analysis of the structural system.
