Abstract
SRC members with high steel ratio possess high load-carrying capacities and significant ductility, which is fully used in high-rise buildings and complex buildings.Finite element analysis is an effective method for investigating the performance of composite columns,but the results of numerical simulation do not agree with test results well,if the confinement of concrete,the damage of concrete and the cyclic hardening of steel under cyclic loading are neglected.Considering the influence of the changes of material,this paper proposed an analysis model for numerical simulation of composite columns by ABAQUS,and the accuracy was verified by contrast between the result of numerical simulation and test.The influence of material changes on numerical analysis of composite columns under cyclic loading were also discussed.关键词
