Project description£º 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.

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

  ¡ñ  A single column is at most as heavy as 896 tons.

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

  ¡ñ  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. 

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