| 摘 要： | 通过6个2/3比例的T形柱框架节点的低周反复试验,考察了轴压比、柱翼缘宽度等因素对节点裂缝开展、节点的破坏机理的影响。提出了翼缘宽度对节点抗剪性能的影响与梁柱抗弯刚度比有关,指出了翼缘板对节点抗剪承载力影响的修正系数ξf须考虑梁柱抗弯刚度比的影响,而不能仅按《混凝土异形柱结构技术规程》(征求意见稿)中的bf-bc来反映。

| Abstract: | Under low cyclic loading,6 T-shaped column joints of RC frame with 2/3 scale were tested.The axial compressive ratio and wing width of columns can be influence on crack distribution and destroy mechanism of the special-shaped column joints.The bending stiffness between beam and column can determine the shear load-carrying capacity of the joints,so it is not enough to use only the factor of b_(f)-b_(c) for evaluating the influence of wing width of column on the shear load-carrying capacity of joints as Technical Specification for Concrete Special Shaped Columns Structure. |

| Keywords: | Frame joints with special-shaped column low cyclic loading test column's wing |
