以截面肢长、再生粗骨料取代率、钢管壁厚和轴压比为基本参数，采用大型通用有限元分析软件ABAQUS，对两种不同肢长的T形钢管混凝土柱模型在低周反复加载下的荷载-位移滞回曲线进行模拟计算，获得T形钢管再生混凝土柱在水平地震荷载作用下的滞回性能、变形能力和耗能能力，从而比较两种不同截面肢长T形钢管再生混凝土柱的抗震性能。相比于普通混凝土构件，再生混凝土构件表现出更好的变形能力和耗能能力。

In this paper,the authors simulated load-displacement hysteresis curve. Taking the cross section of limb length, recycled coarse aggregate replacement ratio,steel tube wall thickness and axial compression ratio as the basic parameters,the research utilized general finite element analysis software ABAQUS in two different limb long T model of concrete filled steel tubular column under low reversed cyclic loading. As a result,the research gained hysteretic properties,deformation and energy dissipation capacity of recycled concrete filled steel tube columns under horizontal seismic load,so as to compare two different cross section limbs long T seismic performance of recycled concrete filled steel tube structure. Compared with or-dinary concrete member,recycled concrete component showed better deformation capacity and energy dissipation capacity.
