摘　　要：呼和浩特盛乐国际机场的建筑设计融入了蒙古包的元素,主楼钢屋盖采用局部斜拉斜交平面桁架的结构形式强化了这一建筑意向。为了解这一新型结构形式的受力特点和验证其可靠性,首先对该屋盖体系的形成逻辑、结构组成和总体受力特点进行了阐述;然后介绍了屋盖结构整体计算指标、温度对该超长屋盖的影响和下部结构分缝对跨缝整体屋盖影响的情况;并基于数值分析研究了与斜拉结构特点密切相关的几个问题,包括梭形摇摆柱的整体稳定、斜拉索索力影响因素、索节点的设计、梭形柱和斜拉索失效对屋盖结构抗连续倒塌的影响等,论证了该新型结构体系的安全可靠性;最后对索的施工张拉顺序和施工模拟分析提出了细化要求。The architectural design of Hohhot Shengle International Airport incorporates elements of yurts,and the steel roof of the main building adopts a structural form of local cable-stayed and oblique plane truss to strengthen this architectural intention.To understand the stress characteristics of this new structural form and verify its reliability,firstly on the formation logic,structural composition,and overall stress characteristics of the roof system were elaborated.Then,the overall calculation indicators of the roof structure,the influence of temperature on the super long roof,and the influence of the lower structure joints on the overall roof across the joints were introduced.And based on numerical analysis,several issues closely related to the characteristics of cable-stayed structures were studied,including the overall stability of the shuttle shaped sway column,factors affecting the cable force of the inclined cables,the design of cable nodes,and the impact of shuttle shaped column and inclined cable failures on the roof structure’s resistance to continuous collapse.The safety and reliability of this new structural system were demonstrated.Finally,detailed requirements were proposed for the construction tensioning sequence and construction simulation analysis of the cables.
