摘要
为了研究钢筋混凝土柱在双向受力及扭转耦合作用下抗震性能,采用矩形、菱形、椭圆形的位移加载模式分别对3个钢筋混凝土柱进行了拟静力试验。根据试验结果对试件的滞回曲线、恢复力特性、累积滞回耗能及损伤特性进行了分析。
Three specimens of reinforced concrete column subjected to biaxial and torsional loading are investigated in this paper. The strength and stiffness degradation under different load path is analyzed, and the accumulative hysteresis dissipation energy and damage indexes are calculated on the basis of test results.Three types of displacement loading modes are applied for the specimens in this study.
