Golden prize of China`s architectural steel structure,
This project consists of stadium, gymnasium, natatorium, and shooting and archery hall. Of which, the gymnasium roof adopts the steel structure: the main central playing field uses the suspendome structure, the training field uses the beam string structure, and other fields use the orthogonal or oblique steel girder structure. The main roof shows a continuous form of folded plate, with the longitudinal axis of symmetry; the longitudinal length of roof is 168.6 meters, the maximum transverse width is 92.4 meters, and the highest elevation of roof is 23.5 meters. The metal roof is decorated with the secondary roof aluminum boards for beautiful shape, and also increasing the overall performance against wind. The metal roof area of gymnasium is 14,570 square meters, and the metal roof area of natatorium is 14149 square meters.
