| 摘 要： | 采用两阶段分析方法，选取不同单元类型对钢塔的整体及局部节点进行有限元数值模拟，先用杆系单元建立整体模型得出节点处各管实际内力，建立节点实体模型并以试验工况进行标定，再依实际内力加载求解，此方法能够有效地结合结构宏观与微观分析，为结构设计提供建议。

| Abstract: | In this article, different elements are chosen respectively to make global and local FEM simulations for a steel tower through a two-stage analytical method. Firstly, we set up a global model with frame element to get actual internal force. Then a solid model of the nodal point is set up and calibrated with testing result. Secondly, we solve the model according to the force computed before. This method associates global analysis with local analysis and gives advice to structural design. |
