［摘要］廈門大學國際會議中心為疊合大跨高大空間、露天大仰角開口斜屋頂結構。以大跨大空間雙層復雜屋面結構為研究對象，通過對主體結構的整體計算控制和加強措施，采用預應力混凝土屋架結構的形式解決露天開口斜屋頂?shù)募夹g難題，成功地解決了跨度大、自重大導致彎矩過大、撓度裂縫過大的問題，以滿足高大空間的建筑功能和獨特的造型。同時闡述其使用階段和施工階段的設計計算及施工階段的應變監(jiān)測，簡述空間斜撐在超長懸挑結構中的應用，有效地解決了工程實際問題，收到了良好的效果。

Abstract:Xiamen University International Conference Center is a sloping roof structure with a large span, a large space, and an open-air large elevation angle. Taking the large-span, large space and double-layer complex roof structure as the research object, through the overall calculation control and strengthening measures of the main structure, the technical problems of the open-air inclined roof were solved by adopting the prestressed concrete roof truss structure, and the problems of large span and heavy self-weight leading to excessive bending moment and deflection crack were successfully solved, so as to meet the architectural functions and unique features of the large space of the building. At the same time, the design calculation and strain monitoring in the use stage and construction stage were described, and the application of spatial inclined strut in the super-long cantilever structure was briefly described, which effectively solved the practical problems of the project and achieved good results.
Keywords:overall structure calculation; prestressed concrete roof truss structure; construction monitoring; spatial inclined strut; super-long cantilever
