The Bird's Nest is the main stadium of the 2008 Beijing Olympic Games. The giant stadium designed by Herzog, De Mellon, Plic Prize winner in 200 1 year and architect Li Xinggang from China is like a "bird's nest" that breeds life, and more like a cradle, which breeds human hope for the future. The designer did not do any unnecessary treatment to the National Stadium, but frankly exposed the structure, thus naturally forming the appearance of the building.
"Bird's Nest" is a large-scale steel structure project with the largest steel consumption, the largest scale, the most difficult construction and many world-class construction technical problems at home and abroad. ? The "Bird's Nest" project is generally contracted by Beijing Urban Construction Group, and Beijing Urban Construction and Zhejiang Seiko Urban Construction Seiko and CITIC Guohua are subcontractors, each responsible for half of the "Bird's Nest" project. ? Mamte Heavy Equipment Transportation and Installation Co., Ltd. undertook the hoisting of urban construction precision steel structures with a total hoisting capacity of 25,000 tons, with an average hoisting capacity of 1 15 tons every two days.
China designers of "Bird's Nest" used a computer CFD simulation method in fluid mechanics design to simulate and analyze the thermal comfort and wind comfort of the audience hall of "Bird's Nest". It can accurately simulate the steel structure and membrane structure of the "Bird's Nest", simulate the natural ventilation when 9 1000 people watch the game at the same time, calculate the temperature and humidity airflow speed that the audience can feel in each area, and mark it with different colors on the drawings. At present, all the ventilation facilities of the "Bird's Nest" are the result of adjusting and optimizing the drawings of foreign designers according to this simulation analysis. Whether the audience sits in the upper stand or the lower stand, ordinary seats or VIP seats, they can enjoy the natural light and wind, and achieve better comfort.
