The original name of "Bird's Nest" is "b 1 1"

"Bird's Nest" has become synonymous with the current national stadium design scheme since the global bidding results were announced to the public, but it was not named by the designer, but was called "b 1 1" in the evaluation process. Li Xinggang said: "We didn't give it a name, but used' Bird's Nest' to describe the structural weaving characteristics of the scheme in the submitted scheme description, 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 ground 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 studied the real bird's nest? Li Xinggang replied with a smile: "It's really interesting for birds to build nests with steel, but we didn't study the nest during the design process."

"Bird's Nest" was changed to "Bird's Nest"

Why should it be designed 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 oval, with a north-south direction. Considering the balance of the audience's line of sight, the stands are designed as bowls with high east and west and low north and south. After that, the designer connected the roof canopy covering the stands with the facades of the functional areas such as 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, that is, the "bird's nest" that everyone saw later.

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'."
