摘　　要：基于蜂窝状钢骨混凝土L形柱低周反复荷载试验的结果,利用大型有限元分析软件,建立蜂窝状钢骨混凝土L形柱的计算模型,并对其在不同轴压比条件下低周反复荷载全过程进行非线性有限元分析。从而进一步对蜂窝状钢骨混凝土L形柱抗震性能影响因素进行分析,并分别建立其有限元模型进行数值分析,得到不同轴压比、剪跨比、体积配箍率及腹板开洞率情况下的蜂窝状钢骨混凝土L形柱的滞回曲线和骨架曲线,分析不同因素对L形柱延性性能以及变形能力的影响。The finite element models of SRC L-shaped columns with differer^t axial compression ratio were created by ANSYS, based on cyclic loading test results of honeycomb SRC L-shaped columns. Then, nonlinear finite element analysis （FEA） was carried on these models under cyclic loading. Based on these, multi-parameter analysis, considering different axial compression ratio, shear span ratio, volume stirrup ratio and hole ratio in steel webs, was carried to study impacts of these parameters on seismic performance of SRC L-shaped columns. Finally, hysteresis loops and skeleton curves of different parameter levels generated, from which the influence of these parameters on ductility of L-shaped columns can be judged.
