Introduction to Olympic venues

The National Stadium project is a special-grade sports building. The main structure has a designed service life of 100 years. The fire resistance level is level one, the seismic fortification intensity is 8 degrees, and the underground engineering waterproof level is 1. class. The main building of the project is in the shape of a spatial saddle oval, 333 meters long from north to south, 294 meters wide from east to west, and 69 meters high. The main steel structure forms an overall giant spatial saddle-shaped steel truss woven bird's nest structure.

The total steel consumption for the steel structure is 42,000 tons, and the grade is Q460. The concrete grandstand is divided into three floors: upper, middle and lower. The concrete structure of the grandstand is a reinforced concrete frame-shear wall structure system with one floor underground and seven floors above ground. The steel structure and the upper part of the concrete grandstand are completely separated and not connected to each other. They are enclosed in form, and the foundation sits on a connected base plate.

The steel structure of the roof of the National Stadium is covered with a double-layer membrane structure, that is, a transparent upper ETFE membrane fixed between the upper chords of the steel structure and a translucent ETFE membrane fixed under the lower chords of the steel structure and on the side walls of the inner ring. The lower level of the PTFE acoustic ceiling.
