Abstract:The roof system of Chengdu Shuangliu International Airport T2 Terminal Building consists of steel arch elements and steel lattice shell elements.In the plan view,the building is composed of seven parts:a main lobby,left and right connection hallways and five boarding bridges. A double layered lattice steel shell structure is used as the roof of the main lobby part,while a single lattice shell structure is used as the roofs of the connection hallways and the boarding bridges.The selection of the roof structure,the stability analysis of the shell structure and some major problems that should be paid attention to while designing,were introduced.
Keywords:steel arch; double layered lattice shell; single layered lattice shell; stability analysis
