往复荷载下圆钢管混凝土柱的参数分析
Parametric Analysis for Concrete Filled Circular Steel Tubular Column under Cyclic Horizontal Loading
【摘要】 本文采用有限元分析软件ANSYS,对15个圆钢管混凝土柱进行了往复荷载作用下有限元分析,得到了柱的滞回曲线、骨架曲线;并据此来分析了轴压比、含钢率、长细比、钢材强度和混凝土强度等参数对圆钢管混凝土柱延性及滞回性能的影响.
【Abstract】 In this paper,fifteen concrete filled circular steel tubular(CFST) columns were analyzed under cyclic horizontal loading by the finite element analysis of ANSYS software.The hysteretic curves,skeleton curves were obtained.Then the parameters such as axial compression ratio,steel rate,slenderness ratio,steel strength and concrete strength,which affect ductility,hysteretic curves and envelope curve,were analyzed.
