钢管混凝土构件的承载力分析

Analysis of bearing capacity of concrete filled steel tube member

分析了钢管混凝土材料的特点与材料力学参数,并采用有限元的块体单元与板壳单元来模拟钢管混凝土柱,对其受力性能和承载能力进行了分析计算,计算结果与轴压试验结果的对比分析表明,有限元计算结果与试验结果吻合较好。

The following paper analyzes the characteristics of concrete filled steel tube material and its material mechanical parameters, carries out analysis and calculation of its force performance and bearing capacity using block and shell unit with finite element to simulate concrete filled steel tube coltLmn, and shows by contrast between calculating result and axial compression testing result that finite element calculating result fits closely with the testing result.
