摘　　要：钢结构支撑塔是工程实际中广泛使用的一种结构形式。针对该类结构的工作环境特点,风荷载是设计时必须考虑的影响条件。以实际工程中的支撑塔为例,采用有限元法构建仿真模型,分析了自重和16级风载对支撑塔的影响,讨论了不同风向条件下支撑塔的结构变形和应力分布。对结构的变形、应力的计算值与设计要求进行比较,计算结果表明:钢结构支撑塔满足设计要求的强度和刚度,不会在16级风作用下产生破坏。该方法可为同类型支撑塔的设计提供参考。The steel supporting tower was a widely used structural style in practical engineering.According to the working condition of the structures,the influence of the wind loading must be considered in the design process.A supporting tower in practical engineering was taken for example,the finite element method was applied to construct the simulation model,and the effect for the supporting tower was analyzed under gravity and 16 level wind loading.The structural deformation and the stress distribution in the supporting tower was discussed under different wind directions.Compared the deformation of the structure,the calculated stress value and the whole design requirements,the results showed that the design requirements were satisfied with the stiffness and strength of the steel supporting tower,and it could not be destroyed under 16 level wind.This method provided a reference for structural design of the similar supporting tower.
