Project description： The stadium is in ellipse shape and can accommodate 100,000 spectators. Its steel structure consists of a glant main truss (triangle steel column + roof truss), elevation secondary structure and roof secondary structure, with total steel consumption of ca. 45,000 tons. The design service life of the main body is 100 years.

  ●  The largest section of trussed column is up to 25m x 20m, equivalent to the area of a baskeball court. 

  ●  A single column is at most as heavy as 896 tons.

  ●  Almost 3000-odd bent and twisted components with various shapes. 

  ●  The project was constructed completely by welding, no any fastening screw was used. The total length of welds is 1.5 times as long as that of Beijing-Hangzhou Grand Canal. 

  ●  A single node has at most up to 14 butt-joints, very difficult in butt-joining to reach required fabrication precision.
