The original name of "Bird's Nest" is "B 1 1". Since the results of the global bidding for the national stadium design scheme were announced to the public, the "Bird's Nest" has become synonymous with the current implementation scheme, but it was not named by the designer, and it was called "B 1 1" in the evaluation process. Li Xinggang said: "We didn't give it a name, but used the word' Bird's Nest' in the submitted scheme description to describe the structural weaving characteristics of the scheme, so that people can understand it more vividly. Later, almost all media reports used this name, but it is impossible to verify from our text who picked out the' Bird's Nest' first. However, this nickname is also appropriate. " The unique grid structure of the "Bird's Nest" really looks like a bird's nest wrapped with branches, and with the lighting effect, it even floats lightly on the earth like a living body. Did the designer draw inspiration from the bird architect? Half of the building materials of Beijing Magpie Nest are steel. Has the designer ever studied the real bird's nest? Li Xinggang replied with a smile: "It is indeed an interesting phenomenon that birds build nests with steel, but we did not study the bird's nest during the design process." Has the "Bird's Nest" been modified or why is it designed to look like a "Bird's Nest"? Li Xinggang said that the "Bird's Nest" is an artistic achievement gradually obtained through rational analysis from the original state of the stadium. First of all, this is an arena. Its main function is to play and watch games. The stadium and the stands are the most important factors. The stadium is a north-south oval. Considering the balance of the audience's line of sight, the stand is designed as a bowl with continuous ups and downs. After that, the designer connected the facades of functional areas such as the roof shed covering the stands and the audience gathering hall behind the stands to form a complete stadium, which conforms to the shape of the bowl-shaped stands and is a continuous undulating three-dimensional shape. Then, the architect of the design consortium designed a braided steel structure for the outer cover, cleverly "hidden" the parallel track beam of the push-pull openable roof, and got the perfect answer that the structure is the appearance, which was later regarded as the "bird's nest". Later, in order to "slim down" the Olympic Games and reduce the project budget, the design of the National Stadium was greatly revised, with the openable roof removed and the ceiling opening enlarged. Architects and engineers once again carefully woven the stadium structure, completely retaining the characteristics and essence of the original design. Li Xinggang said, "It is still a' bird's nest'."
