【摘要】 对1榀四层单跨宽肢异形柱-混凝土砌块墙组合结构在低周反复荷载作用下进行了拟静力试验研究.探讨其工作性能,破坏特征以及对其抗震性能的影响,着重分析其延性、滞回特性、骨架曲线及刚度退化等问题.研究表明:宽肢异形柱-混凝土砌块墙组合结构承载力、抗侧刚度、延性系数较宽肢异形柱框架相比有较大幅度提高,属于典型的梁铰破坏机制,符合结构抗震的多道设防原则.更多还原

【Abstract】 A one side 4-story composite structures with broad limb specially shaped columns &concrete block wall is conducted under low cyclic and repeated static load.The seismic behavior,ductility,characteristic of resilience,skeleton curve,and degeneration of rigidity are studied in the experiment.Test results showed that the composite structures with broad limb specially shaped columns &concrete block wall has a typical destructive mechanism of hinged beam,and the capacity,ductility,and lateral rigidity increases greatly,and consistent with the seismic multi-channel security principles.更多还原
