August 9, 2003 morning,[link widoczny dla zalogowanych], the National Stadium project valid partners signing observance, the Chinese CITIC Group as the representative of the Commonwealth, the National Stadium project finally became corporate partners bidding the obtaining bidder. The consortium members include the Beijing Urban Construction Group Co., Ltd., the United States Golden State Holding Group Corporation and the State of An Yueqiang CITIC Group Limited. Winning consortium and the project company jointly built Beijing Guozigongsi, the project corporation will receive the 2008 Olympics National Stadium after the 30-year right to operate. Guozigongsi 30 years do not partake in dividends, commerce regained well after the breath of the stadium. Information provided by Beijing Olympic Organizing Committee, as of now, the Beijing 2008 Olympic Games chief stadium and narrated facilities project lawful tender has been successfully concluded, legal tender to complete the project work such as the National Stadium, 6 projects with a total investment of 20.5 billion, of which 85% of the 17.4 billion yuan of asset via the project legal tender, the use of mall mechanisms to complete the financing.
"Bird's Nest" shape structure is prevailed by a huge steel door with a total of 24 truss columns, truss 20 has been completed the entire col and two columns under the col loading. National Stadium Roof saddle-shaped, long axis of 332.3 meters and 296.4 meters short axis, the maximum altitude of 68.5 meters, the minimum height of 42.8 meters. Maintaining the "nest" without changing the architectural neatness, the new design of the structure and layout, structure cross-section manner, material utilization and other issues for a more actual correction and optimization. The incipient design of the roof can be opened in the cancellation of the roof opening to distend, and through optimization of steel greatly reduces the volume of steel. Long span roof truss columns assisting the 24 on the column spacing is 37.96 meters. Around the navel of the main truss roof opening radial layout, with 22 specimens of direct or near through the main truss. To avoid overly complicated knot, a small hack approximate the main truss in the inner ring. Extensive use of steel plates welded attach by a box-shaped component, cross-layout of the main truss and the roof and the elevation of the secondary structure together to form a "nest" of special architectural style. Some of the main grandstand with a walls of strengthened concrete frame structure system, with large span steel structure entirely disengaged
Speaking of Q460 iron, most people may not comprehend. "Nest" devise strange novel, yet this period it's steel structures, there are numerous peerless Q460: Q460 namely a cheap alloy tall strength steel, it is the compel strength of 460 MPa ambition happen when the plastic distortion, The strength of steel than the mean great, so the making is quite laborious. This is the first time in the establishing framework steel Q460 descriptions; and the use of the plate thickness of 110 mm, was formerly distinctive in the citizen standards, Q460 highest thickness of merely 100 mm. Before the steel generally from Luxembourg, Korea, Japan imports. In order apt "nest" to cater "fit" of the Q460, beginning from September 2004, special steel vegetation of Henan Wuyang researchers began their scientific and technological research extra than six months, before and behind 3 trial has finally been successful. Now, as the "Bird's Nest" as the Q460 steel has begun hunk production. 2008, 400 tons of neutral innovation, mastermind property rights of servant Q460 steel, will support up the "nest" of steel frame reinforcement.
In increase, the interior roof of the main truss structure, lifting and installation elevation outlooks in full sway. "Nest" of steel secondhand in steel up to 11 cm thick, had never produced in the country. In appending,[link widoczny dla zalogowanych], in the "Bird's Nest" at the top of the grid structure will be affixed with the outer surface wafer of translucent layer. With this membrane, the stadium is not direct incoming light, but by radiate reflection, the light softer, resulting in the radiate light tin too solve the problem inside the livelihood of the lawn, but were for the seats and shelter for feature. More Creative design is namely the "Bird's Nest" stadium outdoor the whole slightly hoisted terrain, the terrain will be a lot of ancillary facilities to the emulating This avoids the expense of the excavation below the mammoth investment, and uplift the edge of sloping land in the outdoor plaza slowly descended, along to latent site built into the warm-up for 2000 open-air seats, the alphabetical integration with the surrounding surroundings, and once another retention the investment.
Many peruse the "nest" design prototype of people have described: it is a tree-like steel with a capacity of 10 million people in the stadium woven into a lukewarm nest! Nurture and enthusiasm for the life of the "nest", sustenance of people hope for the hereafter. Chairman of the Vetting Committee, the Chinese Academy of Engineering remarked Guan Zhao Ye,[link widoczny dla zalogowanych], this building without whichever more processing, always the resulting image for of its function, architectural form and structural details of natural unity. Architectural Review Committee and many other industry experts deem that the "nest" for the 2008 Olympic Games will not only establish a unique and historic landmarks, but also the history of architecture in the globe will also have ground-breaking significance for the 21st Century building development and the globe witnessed history.
To design and build the "nest" is not cozy, let the "nest" in the coming days even more difficult is full of animation and vitality. According to reports, the "nest" design at the beginning and deepening of the design process, has been pervaded with the thrifty Olympics and the notion of sustainable evolution, to encounter the use function under the premise of the Olympic Games, give full attention to the permanent facilities and temporary facilities in balance. In accordance with the requirements of the "nest" a total of 100,000 seats, of which 80,000 are lasting, and the other twenty thousand temporary addition during the Olympic Games.
