Abstract:T2 terminal of Guangzhou New Baiyun International Airport has  length of 1 088m from east to west and width of 597m from north to south. The lower part is  reinforced concrete frame structural system and steel roof adopts grid structure. The concrete structural design condition of the engineering was introduced from three aspects of the foundation design, the upper structure layout and the performance-based seismic design analysis. Measures in design were taken aiming at some key problems and the measures were introduced in detail, including foundation design in complex Karst area, super-long concrete structure design without temperature joints, large-span super thick prestressed concrete hollow-slab, concrete special flat beam design and column connection design.

Keywords:Guangzhou New Baiyun International Airport; terminal; super-long structure; pile foundation; Karst area; performance-based seismic design; beam-column connection
