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 study the influence of bond strength on the axial compressive properties of CFST, based on the reasonable constitutive model of steel and core concrete, finite element software ABAQUS was used to study the influence of bond strength on the axial compressive properties of CFST. The results show that the bond strength between the steel pipe and the core concrete has little effect on the axial compressive performance of the concrete filled steel tubular.
