摘要
以分离式实体建模方法,利用面-面接触命令考虑型钢与混凝土之间的滑移影响,建立了埋入式钢柱脚节点ABAQUS有限元模型,考虑材料非线性和几何非线性,模拟单调加载全过程并进行了特征值屈曲分析,有限元结果与试验结果吻合较好.在此基础上,研究了边柱埋入式柱脚U形钢筋设置,埋入深度,栓钉设置对柱脚转动刚度的影响,给出钢柱脚合理构造要求.
Based on the face to-face contact and slip of steel and concrete, nonlinear finite element analysis was performed using 3D solid separate model to simulate the complete process and linear buckling under monotonic loading, geometric and material nonlinear was taken into account in the models. The results of analysis are compared with the test ones. Based on the proposed model, parametric analysis was carried out to study the effect of U-type reinforcement, embedded depth, the distribution of studs, in looking for the reasonable structural requirements.
