摘 要: | 本文建立了钢管混凝土的非线性有限元模型,对其在往复荷载作用下的滞回性能进行了数值模拟。有限元模型考虑了反复荷载作用下混凝土的损伤、构件的几何非线性以及钢筋和内钢管与混凝土之间的粘结滑移。算例分析结果表明,有限元计算和试验结果总体上吻合良好。

Abstract: | This paper develops a nonlinear finite element modeling(FEM) to simulate concrete-filled steel tube reinforced concrete column with square section under cyclic loading.In the FEM,the cumulative damage of concrete under reverse loading,nonlinear geometric behavior,bonding-slip between steel bars or steel tube and concrete are considered.Good agreement is obtained between the experimental results and the predictions based on the FEM. |
