| 摘 要： | 对10根T形柱节点进行了低周反复荷载作用下的试验研究,着重分析了T形柱节点的承载能力和破坏特点,梁、柱主筋和核心区箍筋应力变化;实测梁端的荷载-位移滞回曲线,研究轴压比、配箍率对节点核心区受剪承载力和延性性能的影响。并把试验结果与混凝土规范中矩形柱节点计算公式进行了比较。

| Abstract: | Ten RC joints with T-shaped columns under cyclic loading were tested.The specimens were designed to fail in the joints in order to study the failure behavior,load-bearing capacity,crack development law and the hysteresis behavior.The effects of axial compression ratio and the volumetric ratio of stirrups in the core on ductility and shear bearing capacity of specimens are discussed.The tested shear strength of joint with T-shaped columns is compared with that calculated by the formulas of shear strength of rectangular columns given in the code for design of concrete structures. |
