| 摘 要： | 建造于地势较高山顶上的广告牌是一种大跨、高层的构筑物,主要承受水平荷载。以浙江省湖州对坞山巨型广告牌工程为背景,通过对几种可行方案的对比分析,论述了结构选型的重要性,指出了网架筒体结构是适用于该工程的结构类型,在此基础上对影响其受力性能的两个重要参数作了计算分析。同时,风荷载的取值问题是该工程设计的关键,根据规范要求,详细地论述了计算网架筒体结构风荷载的简单方法。其结论可为大跨、高层的类似构筑物的结构选型、设计提供参考。

| Abstract: | The giant billboard in Huzhou,Zhejiang Province,which was built on the peak of Duiwu Hill with an elevation of 100 metres,is a large-span and high-rise building.By introducing the architectural characteristics of the building and comparing the grid tube structure system with some other feasible systems,the significance of selecting proper structural type is discussed and then indicates the grid tube structure is the proper one.Two vital parameters of the grid tube structure are analyzed for better behaviors of structure in detail.Finally,a simple method for calculating wind load is proposed for this special structure according to the load code.The conclusions may be a reference for similar large-span and high-rise buildings. |
