Abstract:The cantilever structure of Shandong communication technology institute is designed with the combination of longspan steel truss structure and membrane structure. The structure has the characteristics of long span and irregular appearance. The layout of the structural system and the process of the static and dynamic analysis are described in detail. The installation method is introduced briefly. The conclusions about this kind of structure are presented for designer to refer.
