摘要
基于非线性有限元软件ABAQUS建立了方形钢管煤矸石混凝土柱-钢梁节点有限元模型,通过合理选择材料本构关系和损伤失效准则,构建钢管和煤矸石混凝土之间的界面模型,改变轴压比、焊缝屈服强度等参数,对方钢管煤矸石混凝土梁柱节点模型在双向循环荷载作用下进行有限元分析,研究考虑焊缝强度的方钢管煤矸石混凝土梁柱节点受力性能对整体构件的影响。
The finite element model of gangue concrete filled square steel tubular column-to-steel beam connection is established based on finite element software ABAQUS. Through reasonable selection of material constitutive relation and damage failure criterion, the interface model between square steel tubular column and gangue concrete is established. By changing the axial compression ratio and weld yield strength, the finite element analysis of gangue concrete filled square steel tubular column-to-steel beam connection model is conducted under bidirectional cyclic loadings. The influence of the mechanical behavior of gangue concrete filled square steel tubular column-to-steel beam connection considering the weld strength on the integral members is studied.
