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
