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。
利用大型有限元軟件ANSYS對蜂窩狀鋼骨混凝土T形柱在低週反複荷載作用下的抗震性能進行分析,併攷慮不同軸壓力繫數、剪跨比、體積配箍率、鋼骨開洞率等參數對蜂窩狀鋼骨混凝土T形柱的影響。分析結果錶明：軸壓力繫數和剪跨比對試件的延性有很大影響;而體積配箍率對于提高柱子的延性和承載力有一定貢獻,但不顯著;適噹的鋼骨腹闆開洞率可以提高試件的延性和承載能力。

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.
