Abstract:The actual project No.2 Jianyang Culture and Sports Centre was taken as an example, the design process of hollowed-out metal curtain wall, including the comparison of style selection and the application of BIM were introduced  systematically,  focus on steel structure design of the connection system which between the building surface and the main structure. The main points of the curtain wall steel structure design of the stadium buildings were summarized. And large-scale finite element software was used to analyze and research the steel structure of the curtain wall. The results show that the calculation results meet the requirements of the specification.

Keywords:curtain wall; steel structure; BIM; hollowed-out metal surface; special-shaped surface
