摘要
根据 5根斜向受力方钢管混凝土框架柱的滞回性能试验 ,总结了斜向受力方钢管混凝土框架柱的水平荷载—位移滞回曲线的特点 ;分析了加载角度、轴压比、宽厚比 (含钢率 )和长细比 4个控制参数对荷载—位移滞回曲线的影响 ,并对试验试件的耗能比、位移延性系数、单位体积耗能比进行了分析 .结果表明 ,方钢管混凝土框架柱具有较好的抗震性能 .
Based on experiments, 5 specimens of concrete-filled square steel tubular frame columns under oblique horizontal loading, characteristics of hysteretic curves for this type of columns are summarized firstly in this paper. The effects of loading angle, axial ratio, width-to-thickness ratio and slenderness are presented. Finally, comparison of dissipating energy ratio, ductility ratio and per-volume dissipating energy ratio are studied.
