［摘要］黄金湾旅游综合体运动休闲中心平面形状呈8字环状，为带大跨桁架的钢框架\|支撑体系，整个结构总长约222m，最大宽度82m。基于建筑功能的需要，屋面高低交错，形成一个8字环状滑雪跑道，因此结构多处形成局部错层。整个结构主要由西侧的钢框架-支撑+均匀分布的钢框筒以及连接各框筒的大跨桁架构成。结构平面复杂，多种结构体系交错连接，设计时主要着眼于以下几点：制定合理的抗震性能目标，确保关键构件的抗震性能；均匀布置抗侧力体系；优化设计大跨度桁架；连接处保证力流传递的流畅和合理。此外对大跨度桁架进行了楼板应力分析和舒适度分析。选取关键节点进行了有限元分析，确保关键节点的受力可靠。鉴于结构平面、空间关系复杂，对该项目进行了BIM设计，实现了各专业协同设计，提高了管道综合设计的准确率。

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.
