摘　　要：通过双向拟静力实验，研究钢筋混凝土柱在双向受力下的相互影响，特别是不同加载路径下破坏特点，分析比较钢筋混凝土柱在不同的双向加载路径下的累积滞回耗能和损伤情况。实验采用了目前结构抗震中比较常用的六种加载规则，实验是以位移控制的加载方法进行的。Seven specimens of reinforced concrete column under biaxial loading were investigated in this paper. The decrease of strength and stiffness under different loading paths was analyzed, and the cumulative hysteresis of dissipated energy and damage indexes were calculated by the test results. The rules of six kinds of loading commonly used nowadays were applied for the biaxial loading. Displacement control mode was adopted as the load method in this experiment.
