Abstract:The plane of  Changchun Longjia International Airport T2 Terminal  is a herringbone layout. The structural system is a reinforced concrete frame, and the roof adopted square pyramid space grids, supported by tapered columns. According to the situation of site, the two schemes of the backfill compacted pile foundation scheme and the underground overhead  pile foundation scheme below ±0m elevation were compared, and the underground overhead  pile foundation scheme which can reduce the negative friction effect of the pile is determined as the optimal scheme. According to the characteristics of the building, space truss roof structure can better achieve the building shape, and at the same time the size of each structural unit was controled as much as possible to weaken the torsional effect of the traveling wave effect on the structure. According to the space characteristics of departure hall, the scheme of cable net curtain wall facade was selected to make a more concise fa-ade. Effective measures were adopted to solve the problem of deformation coordination of the super long cable net curtain wall.

Keywords:Changchun  Longjia International Airport; negative friction; cable net curtain wall; deformation coordination
