( Xian Dai Architectural Design Group,Shanghai Institute of Architectural Design & Research Co. ,Ltd., Shanghai 200041, China)Abstract: The China Maritime Museum, which located in the Lingang New Town of Shanghai is a new symbolic structure, especially the central shell lain on the roof of a three-storied reinforced concrete building, which gives a strong visual impact to the visitor and declares China's ambition towards the ocean in the new century. The central shell is a complicated hybrid-structure, the building materials of which contain almost every category: reinforced concrete, steel, steel cable, glass as well as compound Al-alloy slab; its structural system is also hybrid by making the following items up: frame, truss, panel, cable-net together with glass curtain wall. This article contributes a systematical research on the design theory of this neotype hybrid-structure aimed at finding an optimum agreement between the art of architecture and the structure safety, in order to gain experience and popularize this type of excellent novel structure with strong sculpture feeling.
Keywords: single-layer cable net; neotype hybrid-structure; ruechanical difficulties; measure and test of cable force
