CCTV headquarters American "time" magazine named the 2007 ten worldwonders,which ranked CCTV headquarters.
Introduction
CCTV headquarters (CCTV Headquarters) is located in the east of BeijingCBD,the designer:REM Koolhaas (Holland).When completed the ladder structure,it will become the most aggressive design buildings in the world.It is American "times" magazine (December 24,2007 ahead of publication) as one of the ten wonders of the 2007 world.In 2007 ten major architectural wonders,Beijing will have three (the other two as Beijing Dangdaimoguocheng and Beijing Olympic Stadium).But because of the building other expensive (about 5000000000 yuan),too strange,safety anddanger to traffic and controversial.
In section B of this project will be the first step in 2007 completed by the end of the year,early 2008 delivery,this also will serve as the Beijing Olympic Broadcasting Center and CCTV program production and broadcastingcenter.The A section will be completed by the end of 2008,2009 delivery,this section mainly Television Cultural Center,management center.
[editor this paragraph] design and review
5 years ago,when the Dutchman Rem Koolhaas and German ole Scheerenannounced their plans of CCTV new headquarters building,people can hardly believe building can do.
Technically,there is a big difficulty in the building.Architectural appearanceis just like a distorted square doughnut; two vertical tower inclined angle,great; between the turret is connected by horizontal structure,the overallform a closed ring.
Such a convolution type structure is not ready to follow construction standards in the construction industry.
Koolhaas and Scheeren thinks,this kind of structure is a challenge to thetraditional concept of building industry.People usually think thatskyscrapers should Touch the Sky directed at the sky.
Now,the construction of the building will soon enter key:a few weeks later,the workers will start on the transverse structure construction.This part of the technical requirements of sounds like something from a science fiction novel:the two towers connected in midair,must be in the sun before construction,because the expansion steel structure sun will make different parts of the tower,which is not conducive to control the construction quality.
About 10000 new buildings are under construction in Beijing,the CCTV building is probably the most can display an ambition,people on theconstruction industry called Beijing foreign architects "Oriental gold rush","experimental field",often can use it as a typical representative of.Scheeren says the possibility,this structure could be built in other parts of the world is very small,because the building code in other places will not allow such things.And China is willing to try,this creates a very special atmosphere for architectural design.
To host the Olympic Games successfully,China government hopes to letBeijing this ancient city,into a modern metropolis.In all of the new building,the new CCTV building design cost $800000000,to the public the strongvisual impact.After completion,it will become the symbol of this China,CCTV only national TV at the same time,it is second in size only to AmericaThe Pentagon the world's second largest office building.
The project will start from the end of this month the CCTV building main body,wherein the cross structure suspension will eventually in February next year before completion.When served as a design competition CCTV building the Hongkong architect Yan Xunqi said,at first he holds quite a reserved attitude towards the "extremely crazy design",but later,he felt this design can represent "a spirit,this spirit is Chinese show out things in the new time:do not fear of authority,dare to try,be fearless,a high level of confidence".
The connection part of tower structure from the bridge building techniques,different is,if the part as "bridge",it will be a surprisingly large,cumbersomebridge.Some parts of this bridge is a full 11 storeys high,the bridge also includes a protruding 75 meters in front of the cantilever,without anysupport.
According to the Convention,after the design stage,constructionsupervision and often borne by local architect.But in order to make the design better implemented,the 36 year old secretary in 2004 has made an unusual decision:to move to Beijing to supervise the construction.
Beijing construction industry and can be used for a building of this design,there is no ready-made specification,Beijing City Hall organization of 13 structural engineers have set up a special team.In the design competitiontwo years later,the new CCTV headquarters to start construction.Next,the expert group to do a 3 storey high replica of the study.It is placed in asimulated earthquake hydraulic platform,installed hundreds of sensors,used for the displacement monitoring "tower" on more than 1 steel beams,and measured under which parts under different conditions of maximum pressure.
CCTV outside the building by large windows and rhombic steel meshtogether,as the main building structure,the steel mesh is exposed to theoutside the building,not like most buildings that inside.Scheeren says,such pressure can pass down the system,and find the best path into the ground.Look from the exterior,the building has a steel net structure(including corner pressure parts) are intensive,they are part of the overalldesign idea.
In addition,outside the building will use a special glass,whose surface isfired to gray enamel,can effectively shade from the sun
