After the Olympic Games, it became a large-scale professional place for Beijing citizens to participate in sports activities and enjoy sports entertainment, and became a landmark sports building and Olympic heritage.
The stadium was designed by Jacques Herzog, De Mellon, Ai Weiwei and Li Xinggang and built by Beijing Urban Construction Group. The shape of the stadium is like a "bird's nest" and cradle that breeds life, and it entrusts human hope for the future. The designer did not do any unnecessary treatment to the site and exposed the structure, thus naturally forming the appearance of the building.
On February 24th, 2003, the project started +65438, and was completed in March, 2008, with a total cost of 2.267 billion yuan. As national landmark buildings, the main stadium and the national stadium of the 2008 Olympic Games have remarkable structural characteristics. The stadium is a super sports building and a large-scale sports venue. The design service life of the main structure is 100 years, the fire resistance rating is Grade I, the seismic fortification intensity is Grade 8, and the waterproof rating of underground engineering is 1.
20 14 In April, China Top Ten Contemporary Buildings Selection Committee preliminarily selected 20 buildings from more than 0/000 national landmark buildings, integrating four indicators of age, scale, artistry and influence. Finally, the top ten contemporary buildings came into being. Beijing Bird's Nest-National Stadium is one of the finalists? .

Extended data
The external structure of the "Bird's Nest" is mainly composed of a huge portal steel frame and 24 truss columns. The design service life of the main structure is 100 years, the fire resistance rating is Grade I, the seismic fortification intensity is Grade 8, and the waterproof rating of underground engineering is 1. The main building of the project is a space saddle-shaped oval with a length of 333 meters from north to south. The huge space saddle-shaped steel truss weaves a "bird's nest" structure. The total steel consumption of the steel structure is 42,000 tons, and the concrete stands are divided into upper, middle and lower floors. Underground 1 floor of concrete structure of grandstand.
7-story reinforced concrete frame-shear wall structure system 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 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 inner ring side wall.
