摘　　要：利用大型有限元软件ANSYS对蜂窝状钢骨混凝土T形柱在低周反复荷载作用下的抗震性能进行分析,并考虑不同轴压力系数、剪跨比、体积配箍率、钢骨开洞率等参数对蜂窝状钢骨混凝土T形柱的影响。分析结果表明:轴压力系数和剪跨比对试件的延性有很大影响;而体积配箍率对于提高柱子的延性和承载力有一定贡献,但不显著;适当的钢骨腹板开洞率可以提高试件的延性和承载能力。The use of large finite element analysis software ANSYS on honeycomb steel reinforced concrete Tshaped column under low cyclic loading the seismic performance analysis,and considering the axial pressure coefficient,shear span ratio,stirrup ratio,steel reinforced opening rate and other parameters of honeycomb steel-reinforced concrete T shaped column effect.Analysis results indicate： axial compression ratio and shear span ratio on the ductile has great influence;and volume-stirrup ratio to improve the ductility and bearing capacity of post has a certain contribution,but is not remarkable;appropriate steel web opening rate can be enhance the ductility and bearing capacity of check bar.
