摘　　要：深圳湾体育中心钢结构屋盖平面约530m×240m,其单层网壳为复杂的空间曲面网格结构,采用箱形弯扭构件编织而成的四边形网格构成。竖向支撑系统包括支撑网壳的31棵树形柱、支撑网架的V形柱、观景桥立柱和下沉广场西立面幕墙柱。从结构规模、复杂和难易程度来讲,在给设计带来挑战的同时,也给工程师提供了设计创新的可能。介绍了钢结构的体系组成及特点和结构的设计创新内容,包括超长结构不设缝、弯扭构件的可编程图纸表达、结构建模及设计方法的创新以及自主编制的质量验收标准,为工程的设计完成提供了保障。As a super-long span spatial structure, the steel roof structure of Shenzhen Bay Sports Center is composed of single-layer latticed shell, two space grid structures and vertical support system. The single-layer latticed shell is a complex spatial surface, which is meshed by quadrilateral grids with crooked-torsional box-section members. Vertical support system includes 31 dentritic columns, V-shaped columns, columns of bridge pier and latticed columns of west curtain wall. An introduction is given for the structural system of steel roof and its special features. Several innovative structural design aspects are elaborated, such as super long structure without temperature joints, the programmable expression of drawings for crooked-torsional members, innovative methods used for structural modeling and design, independent project standards for acceptance of construction quality and installation errors, and so on.
