摘要
在选择合理的材料本构、破坏准则和裂缝模型的基础上,建立一个三维非线性有限元计算模型,进一步分析新型钢管混凝土柱-平板节点在轴压情况下的裂缝形态和受力性能等,分析结果表明,有限元模型计算结果与试验结果吻合良好。
Based on the appropriate material constitutive equation, failure criterion and model of cracking and crashing, a 3D nonlinear finite element method (FEM) computative model is presented to further analyze the crack form and mechanical properties of this new-type concrete filled steel tubular column-slab joint on axial compressive condition. Calculation results show that a good agreement between the experimental and analytical results can be obtained.
