The Bird's Nest, together with the nearby Water Cube, represents the traditional Chinese concept of "round heaven and square earth," as well as the "Qian-kun" and "Yin-yang" ideas. The Bird's Nest is a Beijing's landmark building which represents the most advanced steel structure building system and it support the development of the future building.
Design and construction:
Located in the Olympic Green, the stadium cost US$423 million. The design was awarded to a submission from the Swiss architecture firm Herzog & de Meuron in April 2003 after a bidding process that included 13 final submissions. The design, which originated from the study of Chinese ceramics, implemented steel beams in order to hide supports for the retractable roof; giving the stadium the appearance of a "Bird's nest". Leading Chinese artist Ai Weiwei was the artistic consultant on the project. The retractable roof was later removed from the design after inspiring the stadium's most recognizable aspect. Ground was broken in 24 December 2003 and the stadium officially opened in 28 June 2008. A shopping mall and a hotel are planned to be constructed to increase use of the stadium, which has had trouble attracting events, football and otherwise after the Olympics.
The entire structure component of the stadium composes the mutual support to form a grid structure. It looks like a bird's nest and the gray steel mesh is covered by transparent material. It contains a bowl-shaped stadium which is red. Here, the hollow out style, the ceramic lines, the red refulgence and warm, and the most advanced modern steel structure design are perfectly blended together.
The whole building is related through the giant reticular structure, without one column in the interior. The stand is shaped like bowl which give the stadium unbelievable dramaticism and incomparable appeal. The continuous loop will also make the audience get the best view and promote their emotion. It can also encourage players to be faster, higher and stronger. Here, people, really have been given the center position.
The crust of the stadium can be made by the diaphragm, make to completely waterproof. The sun can penetrate through the transparent roof to meet the growth of the indoor turf. During a game, the stands can change through various ways and can satisfy the different requirements of different audiences. During the Olympic Games, 20000 temporary seats are on the top of the stadium and can ensure that everyone can clearly see the whole game. The entrance, the exit and the crowd flow through the regional division and reasonable streamline design had been settled perfectly.
The eastern and western stands of Beijing National Stadium are higher than northern and southern stands, in order to improve sightlines. A 24-hour per day rainwater collector is located near the stadium; after water is purified, it is used throughout and around the stadium. Pipes placed under the playing surface gather heat in the winter to warm the stadium and coldness in the summer to cool the stadium. The stadium's design originally called for a capacity of 100,000 people; however 9,000 were removed during a simplification of the design. The new total of 91,000 would be shaved further when 11,000 temporary seats were removed after the 2008 Olympics; bringing the stadium's capacity to 80,000.The farthest seat is 460 feet (140 meters) from center field. Temperature and airflow of every surface were optimized to increase ventilation.
The stadium is like a huge container, whether the last to see or Lex, will give the impression that distinctive, never erase the image, it is fully in line with the National Stadium in the functional and technical requirements, but also from a general Stadium building long-span structures and the digital screen as the main design technique. The spatial effect of the stadium only has the unprecedented originality, but simple, elegant. From here, people can visit, including the stands of the stairs leading to the entire region, including moving lines. Sports hall, is an indoor urban space, with restaurants and shops, its role is just as Commercial Street Gallery, or square, drawing people yearn afternoon a memorable one..
