Abstract:The podium of Dongguan International Trade Center adopts frame structural system with the column grid of 12m×12m in order to meet the functional requirements in different locations of the building and to consider the rationality of the structure in the meantime, realizing the perfect coordination between architecture and structure. The complex spatial steel roof of podium is irregular spatial curved grid, composed of singlelayer latticed shell and vertical support system. The basic concept and advantages of employing three dimensional parametric modeling were illustrated, and the calculation results of the roof were provided. A 38mspan diagonalspan arch bridge, which was a connected passage of the two parts of podium, was analyzed in detail, including deformation, natural frequency，pedestrian comfort, and the bridge system was optimized to save the materials.
Keywords:column grid transformation; largespan complex spatial steel roof; 3D parametric design; diagonalspan arch bridge; pedestrian comfort
