厦门大学国际会议中心结构设计

厦门大学国际会议中心为叠合大跨高大空间、露天大仰角开口斜屋顶结构。以大跨大空间双层复杂屋面结构为研究对象,通过对主体结构的整体计算控制和加强措施,采用预应力混凝土屋架结构的形式解决露天开口斜屋顶的技术难题,成功地解决了跨度大、自重大导致弯矩过大、挠度裂缝过大的问题,以满足高大空间的建筑功能和独特的造型。同时阐述其使用阶段和施工阶段的设计计算及施工阶段的应变监测,简述空间斜撑在超长悬挑结构中的应用,有效地解决了工程实际问题,收到了良好的效果。

Structural design of Xiamen University International Conference Center

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.
