Abstract:The plane shape of sports and leisure center of Golden Bay Tourism Complex features ‘8’ figure ring structure, and adopts the steel frame-brace system with the large-span truss. The entire structure has the total length of about 222m and the maximum width of 82m. Based on the needs of building function, the roof features ups and downs in elevation to form a ‘8’ figure ring structured skiing track, so there are locally staggered floors in the structure. The whole structure is mainly composed of the steel frame-braces on the west side and the uniformly distributed steel framed tube and the large-span truss connecting each framed tubes. The structure plane is complex, and there is a variety of staggered connected structural systems. The design mainly focuses on the following points: developing reasonable seismic performance objectives to ensure the seismic performance of the key components; evenly arrangement of lateral force resistant system; optimization design of large-span truss; connections to ensure fluency and reasonability of force flow transfer. In addition, the floor stress analysis and floor comfort degree analysis of the large-span truss were carried out. The key nodes were selected to conduct the finite element analysis to ensure the mechanical reliability of the key nodes. In view of the complexity of the structure plane and spatial relation, the BIM design of the project was carried out to realize collaborative design and improve the accuracy of the comprehensive design of the pipeline.
