| 摘 要： | 应用大型有限元程序ANSYS对预应力箱形索塔进行了分析。采用混凝土单元SOLID65和杆单元LINK8分别模拟塔体和预应力钢束,并按实际结构形状真实地建立了锚固区的受力模型,根据索塔受力的实际工况,给出特征点处的应力值。所得结论可供设计和施工参考。

| Abstract: | Using large-scale finite element analysis software ANSYS,the PC box tower was analysised.Adopting concret element SOLID65 and bar element LINK8,the tower and the prestresing force cable were simulated.According to real structure shape,the model of anchorage zone was created and according to the real work condition of the tower,the stress value of characteristic points were obtained.All the result were valuable to the design and construction. |
