摘　　要：与传统的站台单柱双悬挑、双柱双悬挑雨棚相比,无站台柱雨棚视觉效果上通透明亮,客流通行、行包运输上便捷通畅,功能上覆盖面积更大,遮风挡雨效果更好。因其柱网跨度大、建筑高度高的特点,通常采用钢结构或组合结构形式,具备各种优点的同时,也带来了设计计算复杂、施工难度高、后续维保难度大、病害隐蔽性高的通病。文中选取具有代表性的四站雨棚结构,进行了模型建立与有限元分析,统计梁、柱、檩条等关键部位的应力及变形指标,总结了多种结构形式雨棚的关键部位,为后续开展健康监测、病害整治提供了依据。Compared with the traditional canopy structures with single-column double cantilever and double-column double cantilever at the platform,the canopy without columns at the platform is visually transparent and bright.It offers convenient and smooth passenger flow and luggage transportation,covers a larger area functionally,and provides better protection from wind and rain.Because of its large span of column grid and high building height,steel structures or composite structures are usually adopted,which brings about complex design calculations,high construction difficulty,difficult subsequent maintenance,and high concealment of defects in spite of plenty of advantages.Through finite element analysis of four typical structures,the stress and deformation indexes of beam,column,purlin and other key parts are counted,and summarizes the key parts of various structural forms,providing a basis for subsequent health monitoring and disease control.
