摘　　要：为研究粘结强度对钢管混凝土轴压力学性能的影响,基于合理的钢材和核心混凝土的本构关系模型,采用有限元软件ABAQUS对粘结强度对钢管混凝土轴压力学性能的影响进行了有限元分析,结果表明钢管与核心混凝土之间的粘结强度对钢管混凝土轴压工作性能影响不大,本文的研究成果可为相关研究提供参考。In order to the effect of bond strength on behavior of concrete filled steel tube（CFST） subjected to axial compression,based on rational constitutive model of steel and core concrete,the FEA package ABAQUS was adopted to analysis the effect of bond strength on behavior of CFST subjected to axial compression. The results of theoretic analysis show that bond strength between steel and core concrete hasn＇t obvious effect on behavior of CFST subjected to axial compression. The research in this paper may be referred for correlative research.
