| 摘 要： | 为研究钢-混凝土组合转换梁-矩形钢管混凝土柱构成的组合转换框架的受力性能,对1榀组合转换框架缩尺模型进行了竖向荷载和低周往复水平荷载试验。分析了组合转换梁在竖向荷载作用下的刚度及裂缝开展情况以及组合转换框架在水平往复荷载作用下的破坏特点、荷载-位移滞回曲线及骨架曲线、延性、屈服机制和耗能能力等力学性能。试验研究结果表明,在竖向荷载作用下,组合转换梁刚度大,抗裂性能好,满足结构正常使用要求;在水平荷载作用下,转换框架延性好,极限层间位移角大,滞回曲线对称、饱满,耗能能力强。

| Abstract: | In order to study the mechanical behavior of composite transfer frame assembled by composite transfer beam and concrete filled rectangular steel tube columns,experiments with vertical loads and low cyclic reversed horizontal loads were performed on the model structure.For the transfer beam under vertical loads,the stiffness and the anti-crack capability were analyzed.The failure process,the load-displacement hysteretic behaviors,the displacement ductility and the energy dissipation capability were studied i... |
