Application Developments and Prospects of Spatial Structures in China
The application development and innovation of spatial structures in China are reviewed.First,the development history of spatial structures in China is reviewed and summarized.Then,the application developments of space frame structures,cable structures and membrane structures are discussed respectively.In the application developments of space frame structures,the application of space frame structures in large-scale engineering projects and the application of aluminum alloy space frame structures are illustrated.The recent typical applications of space frame structures in large sports venues,in cultural entertainment and exhibition buildings,and in airport terminals,as well as typical projects of aluminum alloy space frame structures in recent years are summarized respectively.In the application developments of cable structures,the engineering practice and innovative application of cable net system,cable dome system,suspen-dome system and wheel-spoke cable structure system in large sports venues in recent years are introduced.In the application developments of membrane structures,the application of membrane structures in large stadiums and indoor sports halls,the application of ETFE membrane structures and the application of air-supported membrane structures are stated respectively.Combined with typical engineering applications,the structural system innovation,engineering practice innovation and new technology development are introduced in this paper.Finally,the future development directions of spatial structures are prospected.
