摘　　要：通过5根角钢加强的钢筋混凝土十字形截面异形柱的低周反复加载试验,分析了不同的配钢率、配钢形式下试件承受压、弯、剪复合作用时的破坏形态。对比ANSYS分析结果,阐述了构件的延性、滞回特性、刚度退化以及耗能能力,证明了构件形式的优异性。Through the low cyclic reversed lateral loading experiment for five cross-shaped RC columns reinforced by angle steel,the failure mode at the combined effect of pressure,bend and shear with different steel ratios or different reinforced forms was analyzed.According to the comparison of the analysis results with ANSYS,the ductility,hysteretic characteristics,degradation of stiffness and energy dissipation capacity were analyzed and the advantage of this kind of columns was verified.
