【摘要】 对2榀单层单跨T形截面混凝土柱-混凝土砌块墙结构和1榀钢筋混凝土T形截面柱框架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:T形截面混凝土柱-混凝土砌块墙结构承载力、抗侧刚度、延性系数较空框架相比有较大幅度提高,符合结构抗震的多道设防原则,属于典型的梁铰破坏机制,可为今后类似多层多跨结构的设计及理论分析提供依据.更多还原

【Abstract】 A comparing 1∶2 models experiment between reinforced concrete T-shaped column-concrete blocks wall structure and T-shaped column frame structure 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.It was shown by the test results that reinforced concrete T-shaped column-concrete blocks wall structure has a typical destruction mechanism of hinged beam,and the capacity ,ductility,and the lateral rigidity,all increased greatly.The seismic behavior of R.C.T-shaped column-concrete blocks wall structure is satisfactory.更多还原
