Abstract: The phase Ⅲ new terminal area project of Hangzhou Xiaoshan International Airport contains Terminal 4, groundtransportation center (GTC) , energy center and supporting buildings. The structural system and key issues in structuraldesign of main building of Terminal 4 were mainly introduced. Targeted design measures were proposed for the relationshipbetween the terminal and underground space. The vibration response of the co-construction area of the main building ofterminal, the high-speed train station and the metro station was analyzed using the soil-structure-track finite elementmethod. The large openings of the first floor of the main building of terminal were investigated to propose the reasonablecalculation and analysis assumption and structural measures. To solve the design problems of the large-span complex steelstructure roof, the architecture-structure harmony design was considered. The anti-progressive collapse performanceanalysis, the traveling wave effect analysis, the nonlinear stability ultimate bearing capacity analysis and the mechanicalproperty analysis of key joints of the steel roof were carried out by using the finite element software. The structurecalculation software was applied in the analysis of the temperature effect of the main building to propose reasonable designmeasures. The analysis results show that the vibration safety and comfortableness of the main building of Terminal 4 satisfythe specification requirements. The effective transmission of the earthquake action in the large openings of the first floor canbe ensured. The coordination between attractive architecture and reasonable structure is realized in the steel roof design.The structural design of this project is safe, economical and reasonable.

Keywords:Hangzhou Xiaoshan International Airport; underground space; large-span complex steel structure; super longstructure; vibration analysis; comfortableness analysis; anti-progressive collapse design
