| 摘 要： | 利用ABAQUS软件,运用位移加载的方式,对不同温度下组合柱进行全过程曲线模拟分析,并把不同温度下模拟结果的极限承载力与公式计算的极限承载力进行比较.基于统一理论的分析方法,得出ABAQUS模拟结果与公式计算结果吻合较好,且具有较高的承载力,混凝土的塑性和韧性有所增加,为工程应用提供了理论依据.

| Abstract: | Software and the displacement loading method are used to analysis the whole process of composite columns under axial pressure, and the ultimate bearing capacity of the simulation results are compared with the ultimate bearing capacity of the formula. A conclusion is drawn that the steel tubular filled with steel-reinforced concrete can improve the ultimate bearing capacity and the concrete＇s plasticity. |
