摘　　要：基于Open SEES有限元软件对复式钢管高强混凝土短柱轴心受压性能进行模拟。考虑到钢管对混凝土的强化作用,选用Mander混凝土本构模型作为混凝土强度依据,针对外方内圆的复式钢管高强混凝土进行建模。将模拟结果与试验结果进行对比分析。结果表明:文中Open SEES建模方式与模型参数选取合理,模拟结果与试验结果吻合较好,复式钢管高强混凝土柱的有限元分析可以参考文中的建模方式及本构模型进行。The axial compression performance of composite-sectioned high strength concrete filled short steel tubular short column was simulated based on FE software Open Sees. Taking the reinforcing effect of steel tube on the concrete into consideration,Mander concrete constitutive models was selected as the strength basis of concrete to build the simulation for the composite steel tube high strength concrete column with a outer square and an inner circle cross section. The numerical simulation results were compared with the tests measuring results,it turns out that the both results coincide each other better and the Open Sees modeling method and model parameter are reasonable. The FE analysis of composite concrete filled steel tubular column may be carried out according to modelling method and constitutive model proposed in this paper.
