National Stadium design is generated by the global design tender by the Swiss firm Herzog & de Meuron design, Ove Arup & Partners Corporation and the China Architecture Design and Research Consortium co-designed "Bird's Nest" program. The design of the main gate by a series of radiation-type steel truss rotate around the bowl seating areas is made simple spatial structure of science, architecture and structural integrity and unity of novel design, unique structure, unique to the construction at home and abroad. Their owners unit is limited by the Beijing State-owned Assets Management Company and CITIC Group, jointly established the Commonwealth of the National Stadium limited liability company. Beijing Hotel. National Stadium Co., Ltd. is responsible for project investment and financing, design, construction, operation and management. National Stadium on December 24, 2003 started, 2006 completed and put into trial operation.
"Bird's Nest" is the 2008 Beijing Olympic Games main stadium. By the 2001 Pritzker Architecture Prize Laureate Herzog, & de Meuron and Chinese architect Li Xinggang of cooperation such as the completion of the giant stadium design, patterns of life as birth, "nest", which is more like a cradle of the hands of human right hope for the future. Designers of the National Stadium did not do any extra processing, but frankly the structure exposed, thus naturally formed the appearance of the building.
"Bird's Nest" design concept
National Stadium, Olympic Park is located in the Central Region gentle slope on the complex was designed as a container, Highland ups and downs to ease the appearance of the body feeling in the building and given the dramatic and of powerful physique, the National Stadium, the perfect image of pure, Appearance shall be building the structure, facade and structure to achieve a perfect unity. Structural components of mutual support, develop a network-like architecture, it is like the branches woven nests. The spatial effect of the stadium that is unprecedented originality, yet simple and elegant, it has set for the 2008 Olympic Games, a unique historic landmark. 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.
"Bird's Nest" the basic situation of Stadium shell can be used as filling materials using air-cushion film, so that the requirements of the roof be completely waterproof, sunlight can pass through a transparent roof to meet the growth needs of indoor lawn. Game, the stands can be achieved through changes in a variety of ways to meet the amount of different periods and the requirements of the audience during the Games, 20,000 temporary seats are located in the top of the stadium, and can ensure that everyone can clearly see to the entire track. Import, export and crowd flow through the flow line and design of rational division of the region have been the perfect solution.

"Bird's Nest" form factor
Basic Materials
"Bird's Nest" shape structure, mainly by a huge gantry steel frame with a total of 24 truss columns, has now completed the entire 20 truss column and two columns under the column loading. National Stadium Construction saddle-shaped roof, the long axis of 332.3 meters, the short axis of 296.4 meters, the highest point height of 68.5 meters, and the lowest height of 42.8 meters.
Design changes
Maintaining the "Bird's Nest" under the premise of the same architectural style, the new design of the structure and layout, building cross-section form, material utilization issues such as a more substantial adjustment and optimization. The original design of the roof can be opened in the program be canceled, the roof opening to expand, and through optimization of steel greatly reduces the amount of steel. Large-span roof truss columns supporting the 24 above the column spacing of 37.96 meters. The middle of the main truss roof opening around the radial layout, 22 Pin straight-through or close through the main truss. In order to avoid overly complex node, a small cut near the main truss in the inner ring. Extensive use of steel welded together from steel box-shaped components, cross-layout of the main truss and the roof and facade together with the sub-structure, the formation of a "nest" of special architectural modeling. Some of the main grandstand with a shear wall structure of reinforced concrete frame system, with large-span steel structure completely torn off.
The use of steel Q460
Speaking of Q460 steel, most people probably do not understand. "Bird's Nest" structure design peculiar novel, this time to build its steel Q460, there are many unique: Q460 is a low alloy high strength steel, its force strength reached 460 MPa when the plastic deformation will occur , the strength of steel than the average large, so the production is very difficult. This is the first time in the construction structure steel Q460 specifications; but this time using the plate thickness up to 110 mm, this is previously unseen in the national standards, Q460 maximum thickness of only 100 mm. Long ago, such a general steel from Luxembourg, South Korea, imported from Japan. In order to "Bird's Nest" provide "fit" in Q460, from September 2004 start of special steel plant of Henan Wugang researchers began their scientific and technological research more than six months, three times before and after the trial was finally successful. Now, for the "Bird's Nest" has already begun preparations for mass production of steel Q460. In 2008, 400 tons of independent innovation, intellectual property rights of domestic Q460 steel, will be propped up, "Bird's Nest," a steel-framed reinforced. In the "Bird's Nest," where a share of 4.2 million tons of steel.

Beijing Bird's Nest

Special Structure
In addition, the inner roof lifting and elevation of the main truss sub-structure installation in full swing. "Bird's Nest" the thickness of steel used in steel up to 11 cm, had never before produced in the country. In addition, in the "Bird's Nest" at the top of the outer surface of the grid structure will be affixed a layer of translucent membrane. Using this membrane, the stadium is not a direct incoming light, but through diffuse reflection, so that the light is more soft, thus the formation of diffuse light can be resolved inside the lawn maintenance issues, but also promising seats shelter against the elements of the function. Sliding roof that can open the stadium structure will be small part of it. When it together when the stadium will become an indoor venue. As a container lid, whether the roof is closed or open, it is an essential component of the building. In addition to the structure of specific needs, the structure of the roof can be opened basically a network-like structure fitted with inflatable pads, serves as a waterproof shell. "
"Bird's Nest" - lightning does not hurt
"Bird's Nest" looks bare, there is no protrusion of the lightning rod, to encounter thunder what should I do?
In fact, do not worry, because: "Bird's Nest" and the entire steel-boned is an ideal of the "cage-type lightning network." "Bird's Nest" on the metal components in steel and reinforced concrete, etc., are connected together by welding so that the "Bird's Nest" itself to form a huge network of lightning, thunder and lightning can quickly import the underground.
But the "Bird's Nest" with its steel frame to accept, conduction lightning, will not be a crisis to the inside the audience's safety?
This much you can rest assured that experts have taken into account, and any venue where my wife can touch, has done a special treatment, thunder and lightning would never harm humans.
More Creative design is that the "Bird's Nest" stadium outside the whole topography of slightly elevated, a lot of ancillary facilities will be placed in terrain following, this way, avoid digging under the consumption side of the huge investment, while the uplift of the slope in the outdoor plaza of edge slowly descended, according to potential built into the warm-up venue 2000 open-air seats, the organic integration with the surrounding environment, and again to save the investment.
"Bird's Nest" roof of
Sliding roof that can open the stadium structure will be small part of it. When it together when the stadium will become an indoor venue. As a container lid, whether the roof is closed or open, it is an essential component of the building. In addition to the structure of specific needs, the structure of the roof can be opened basically a network-like structure fitted with inflatable pads, serves as a waterproof shell.
"Bird's Nest" symbolic significance
Many read the "Bird's Nest" design model describes the person: It was a like a stick into a steel net that can accommodate 100,000 people into the stadium in a warm nest weave! Be used to nurture and care of life's "nest", is entrusted with mankind's hope for the future.
Components of the entire stadium structure, support each other to form a grid-like structure, appearance looks like a remote branches woven into the nest, its gray mineral-like steel mesh covered by a transparent membrane material, which contains a red soil bowl stadium bleachers. Here, the Chinese traditional culture Pierced approach, ceramics lines, the brilliant red and warm, and modern most advanced steel structure design blending perfectly together.
Structure of the building through the giant network link, could not one column, the stands is a complete no shelter of the bowl shape, like a huge container, giving the stadium with incredible dramatic and unparalleled power to shock. This uniform and continuous ring will also make the audience get the best vision and drive of their excitement, and inspire athletes to the faster, higher, stronger sprint. Here, people really have been given center.

Nest inside
"Bird's Nest" and save resources at
