［摘要］黄金湾旅游综合体游客服务中心建筑形体较为复杂，结构设计存在较多难点。从主次斜交杆偏心连接对结构整体指标的影响进行切入，然后对钢杆件承载力二阶分析、压弯扭构件设计、悬挑部位楼板拉力状态、楼盖舒适度及节点受力性能分别进行阐述。在建筑内环区域处设有玻璃采光顶，支承于结构首层楼面处，为获取良好的通透性与轻巧性，结构方案设计采用了索撑腹杆+四边形单层网壳体系，并对此进行了尝试性计算分析。针对设计难点所采取的技术策略，确保了结构设计的安全性。

Abstract:Architectural form of tourist service center of Golden Bay Tourism Complex is complex, and there are many difficulties in structural design. First, the effects of eccentrically connection of primary and secondary diagonal bar on the overall structure index were studied.Then, the second order analyses were conducted on bearing capacity of steel rods, design review on compression, bending and torsion members, cantilever parts tension state of the floor slab, floor comfort and node force performance were calculated respectively  in detail. There was glass roof in the inner zone of the building to support on the first structural floor. To obtain good permeability and lightness, cable strut web rod+quadrilateral single-layer latticed shell system was adopted in structural design scheme, and trial calculation and analysis were conducted. The technical strategies adopted in view of the design difficulties ensured the security of structural design.

Keywords:Golden Bay Tourism Complex； diagonal bar; steel grid; eccentric steel joint; cable strut
