Abstract:The development history and application status of large span aluminum alloy structure were briefly introduced. The characteristics of single-layer aluminum alloy latticed shell system using plate-typed joints were illustrated from the angles of structural design and construction by taking the typical large-span aluminum alloy projects built in China in recent years as examples. The design process of single-layer aluminum alloy latticed shell of plate-typed joints was similar to ordinary steel latticed shell, and many kinds of flexible construction methods could be used such as high altitude bulk lifting, lifting, and sliding and so on. In view of the problems encountered in the engineering practice and the national standard of Code for design of aluminium structures (GB 50429—2007), the shortcomings of the research on aluminum alloy structure in China were indicated, and the further work and research directions in the future were put forward.

Keywords:aluminum alloy material; large-span spatial structure; single-layer latticed shell; plate-typed joint; design and construction
