What is the traditional bird's nest surrounded by?

Many people who have seen the design model of the "Bird's Nest" describe it as a warm bird's nest made of a stadium with a capacity of 65,438+10,000 people and a branch-like steel net! The "nest" used to nurture and take care of life places human hopes for the future. The components of the whole stadium structure support each other to form a grid-like frame, which looks like a bird's nest woven with branches. Its gray mineral-like steel mesh is covered with transparent film material, which includes a reddish bowl-shaped stadium stand. Here, the hollow-out technology, ceramic lines, the red brilliance and enthusiasm in China traditional culture are perfectly integrated with the most advanced modern steel structure design. The whole building is connected by a huge net structure, and there are no columns inside. The grandstand is a complete bowl shape, without any shelter, like a huge container, which brings incredible drama and unparalleled shock to the stadium. This even and continuous ring will also give the audience the best view, stimulate their excitement and inspire athletes to sprint faster, higher and stronger. Here, people are truly given a central position. It is reported that the length of the athletes' passage, the wardrobe in the athletes' lounge, the ratio of male to female in the audience toilet pit, and the distribution of water diversion points in the media workshop have also become research topics of relevant departments. "Whether it is design, construction or interior decoration, all our starting points are people-oriented, based on the feelings of athletes, based on the senses of the audience, and based on the requirements of journalists." This is a goal of all designers and builders of the "Bird's Nest". 9 1000 spectators "watched" the "Bird's Nest" with a length of 340 meters and a width of 300 meters. There were no columns, but a series of bowl-shaped seats surrounded by radial portal steel trusses. These seats are surrounded by the folding structure of the stadium, and the upper and lower floors are staggered. No matter where the spectators sit, the line-of-sight distance from the center of the stadium is about140m. Three layers of "special devices", including the sound-absorbing film material used in the lower membrane of the "Bird's Nest", the sound-absorbing material set on the steel structure members and the electroacoustic amplification system used in the stadium, make the speech intelligibility index in the "Bird's Nest" reach 0.6-this figure ensures that the audience sitting in any position can clearly hear the broadcast. The designer of "Bird's Nest" also used fluid mechanics design to simulate the natural ventilation of 965,438+0,000 people watching the game at the same time, so that all the spectators could enjoy the same natural light and natural ventilation. In the auditorium of the Bird's Nest, there are more than 200 wheelchair seats for the disabled. These wheelchair seats are slightly higher than ordinary seats, ensuring the same vision for the disabled and the general audience. During the Games, hearing AIDS and wireless broadcasting systems will be provided in the venue to provide personalized services for people with hearing and visual impairment.
