Abstract: Firstly, the characteristics and development of aluminum alloy structure were summarized, and the engineeringapplication and design technical characteristics of large-span aluminum alloy structure at home and abroadwere wereanalyzed. The results show that a complete set of design theory, design method, fabrication, construction and installationtechnology of large-span aluminum alloy structure has been formed in China, some design technology has achievedleadership. Furthermore, the focal points and difficulties of technological innovation were analyzed from the aspects ofaluminum alloy materials, structural system, section form of members, connection joints, etc. Two typical demonstrationcases of aluminum alloy structures,Shanghai Chenshan Botanical Garden and Shanghai World Expo Greenhouse were given,the idea and method to solve the key problems such as the temperature stress of the large-span aluminum alloy structure support were expounded, which plays a good demonstration role in the development , innovation and application of designtechnology.

Keywords:large-span spatial structure; aluminium alloy structure; shell structure; Shanghai Chenshan Botanical Garden;Shanghai World Expo Greenhouse
