Abstract:As a super-long span spatial structure, the steel roof structure of Shenzhen Bay Sports Center is composed of single-layer latticed shell, double-layer 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 beams. Vertical support system includes 31 dentritic columns, V-shaped columns, columns of bridge and latticed columns of west curtain wall. The structural system of steel roof and its special features are introduced, and basic static and dynamic characteristics are presented. Besides, the temperature action and some key issues for structural design are deeply analyzed. The structural stability which controls the design of the structure is investigated in detail. Through dynamic elastic-plastic analysis for rare earthquake, the dynamic characteristics and seismic performance of the structure are fully understood. Finally, joint design criteria and details of key joints are briefly introduced.
Keywords:single-layer latticed shell; support system; temperature action; stability; seismic performance
