| 摘 要： | 计算模型的选取是进行输电铁塔结构分析的首要任务之一。通过建立桁架模型、梁-桁架混合模型和刚架模型,分别对某角钢塔和钢管塔进行建模分析,得出输电塔在常见大风工况下的受力及位移状态。结果表明:对于角钢塔,采用桁架单元能够满足设计分析要求;对于钢管塔,使用梁单元建模分析能获得更加合理的计算结果。

| Abstract: | Selection of an appropriate calculation model is one of the most important jobs for structural analysis of transmission towers.The angle steel tower and steel tube tower are analyzed with the truss model,beam-truss model and rigid model,and the behaviors of the transmission towers under common large wind conditions are obtained.The results show that for an angle steel tower,the truss model can meet the design specifications;while for the steel tube tower,the beam model can give more reasonable results. |
