［摘要］闡述了泰州國際博覽中心二期鋼屋蓋的設計思路。該工程二層展廳分為2個90m×108m的展廳及1個27m跨的過廳，屋面跨度90m。根據建筑師要求，屋面結構設計舍棄了傳統(tǒng)的桁架及網架結構形式，借鑒橋梁結構設計方法，采用大跨鋼梁+斜拉索的結構形式。通過斜拉索及過廳屋面桁架的設置，較好地控制了屋面鋼梁的變形及材料用量，也為斜拉索的固定提供可靠支承條件。
［關鍵詞］大跨度； 斜拉索； 鋼結構； 空間結構

Abstract:The design concept of steel roof system in Taizhou International Expo Centre on the second phrase was introduced in brief. The two-story exhibition hall is divided into two 90m×108m exhibition halls and a 27m-span corridor hall, and the whole roof span is 90m. According to the requirements of the architects, the roof structural design abandoned the traditional truss and grid structural systems, but drew on the bridge structural design method to adopt the structural form of the large-span steel girder + stay cable. Through the setting of the stay cable and the roof truss of corridor hall, the deformation and material consumption of the roof steel girder were better controlled, and the support condition of the stay cable was also provided.
Keywords:large span; stay cable; steel structure; spatial structure
