FRP-混凝土-钢管组合柱滞回性能数值分析

摘要

在确定各材料应力-应变关系的基础上,采用纤维模型法对FRP-混凝土-钢管组合柱在往复荷载作用下的滞回性能进行了数值模拟,建立了FRP-混凝土-钢管组合柱滞回模型。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。%Based on the stress-strain models of FRP,steel tube and the confined concrete under monotonic and cyclic conditions,numerical analysis of load-deflection relationship was put forward,and developed a finite element modeling（FEM） to simulate for Hybrid FRP-Concrete-Steel Double-Skin Tubular Columns under cyclic loading.A good agreement was obtained between the experimental results and predictions based on the FEM.
