Abstract:Kunming new airport is a national key project and will be one of the largest terminals in China. The basic structural system of the terminal building is a reinforced concrete frame with top steel ribbon,850m long in north-south,1 120m wide in east-west. The gross floor area of phase Ⅰ is about 548 300m2. The distance from the airport site to the Xiaojiang fault in southwest China, one of the most active faults worldwide,is about 12km and the site is located in high seismic intensity region. The site spans multiple landform units with terrain fluctuation and karst development. With several faults across the site, the backfill thickness of foundation varies significantly and the base is distributed unevenly. Seismic isolation techniques are applied at the front center area(324m×256m) of the terminal due to structural complexity and unique seismic and geological conditions. Design measures had been applied to solve the problems encountered during the project,which were caused by the super length of the structure, steel ribbon supporting structures and the irregularity of the cable structure of the curtain wall.
Keywords:airport terminal buildings; steel ribbon supporting structure; super-long structures; seismic isolation of foundation; cable structures; curtain wall; multiple-support and multipledimensional excitation
