摘要

在合理选择材料本构关系、破坏准则的基础上

采用通用有限元软件ANSYS对方钢管混凝土柱-钢梁竖向加劲板式节点进行了低周反复荷载试验

以及在低周反复荷载下的抗震性能分析。结果表明:有限元分析得到的滞回曲线和骨架曲线与试验结果吻合较好;试件破坏为梁端破坏

塑性铰出现在梁端

在梁变截面附近出现了局部屈曲

也与试验结果一致。

Abstract

Based on the experiments of concrete-filled square tubular column connections with vertical stiffener under cyclic loading

3D nonlinear finite element models are used to analyze the mechanical properties of connections using ANSYS. Based on appropriate material stress-strain relations and failure criteria

seismic resistance of connections under cyclic loading is analyzed. It is found that the load-displacement curves and skeleton curves by finite element models analyses show good agreement with those of the experiments. The failure and plastic hinge appear on the beam end and the local buckling appears near the section of the variety beam flange. These also agree well with experimental results.
