National Stadium (Bird's Nest) Construction Project
The National Stadium (Bird's Nest) project is a super-Grade A sports building, with the designed service life of the main structure of 100, the fire resistance grade of the first grade, the seismic fortification intensity of 8 degrees, and the waterproof grade of the underground project of 1. The main building of the project is a space saddle oval with a length of 333 meters from north to south, a width of 294 meters from east to west and a height of 69 meters. The main steel structure forms a "bird's nest" structure woven by saddle-shaped steel truss in the whole giant space. The total steel consumption of steel structure is 42,000 tons. The concrete stands are divided into upper, middle and lower floors. The concrete structure of the stand is a reinforced concrete frame-shear wall structure system, with 7 floors underground 1 floor and above ground. The steel structure and the upper part of the concrete stand are completely separated, and they are not connected with each other, but are enclosed in form, and the foundation sits on the connected foundation plate.
The roof steel structure of the National Stadium (Bird's Nest) adopts a double-layer membrane structure, that is, a transparent upper ETFE membrane fixed between the upper chords of the steel structure and a translucent lower PTFE sound-absorbing ceiling fixed under the lower chords of the steel structure and the side wall of the inner ring.
