I am very happy, after years of intense collaboration, that the CCTV building will soon begin to perform its role in the way it is intended. Hal ini dikarenakan mereka harus merancang sebuah rencana struktural untuk membangun dua buah menara dengan sudut kemiringan sekitar 6° dari arah tegak, sehingga setiap menara bangunan membungkuk dan bersandar … The structure of the CCTV Headquarters, and the forces at work within it, is visible on its façade: a web of diagonals that becomes dense in areas of greater stress, looser and more open in areas requiring less support. The structure of the headquarters of CCTV, and the forces acting within the building are visible on the facade: a network of diagonal becomes dense in areas of greater stress, more flexible and more open areas that require less support. Connections must withstand the probable maximum load that was delivered to them from the clamps, with minimal performance and a relatively low degree of stress concentration. The design belongs to the Dutch architect Rem Koolhaas and Ole Scheeren German architect of studio Office for Metropolitan Architecture ( OMA )2002. The structure was a challenge for engineers.

Instead of competing in the race for ultimate height and style through a traditional two-dimensional tower soaring skyward, CCTV’s loop poses a truly three-dimensional experience, culminating in … Its construction is considered a structural challenge, especially because it is in a seismic zone. The building is not a traditional tower, but a loop of six horizontal and vertical sections covering 473,000 m2 of floor space, creating an irregular grid on the building’s facade with an open center. The façade itself becomes a visual manifestation of the building’s structure. This past wednesday, OMA participated in the official construction completion ceremony for the China Central Television (CCTV) Headquarters in Beijing, which will start to be used later this year. An “Open Loop” takes visitors through the building, exposing the daily work of the studies and the history of CCTV, culminating over the cantilever, with spectacular views of the financial district, the Forbidden City and the rest of Beijing. The building was designed to accommodate 10,000 people along with heavy equipment. The building was constructed by joining three volumes created a unique final volume. Connected to the lobby, 12 studies, the largest of 2,000 m2 perform the primary function of the building:create TV. In its upper part were co- joined by a bridge to ‘L’ parallel to the podium.

Rising from a common platform, two towers lean towards each other and eventually merge in a perpendicular, 75- metre cantilever. The facade itself becomes a visual manifestation of the building structure. The CCTV headquarters will be one of the first European skyscrapers to be built in China. This will contain the administration, news, broadcasting, studios and production areas. The 473.000m2 building are divided as follows: 64.200m2 administration 54.900m2 multi – purposes, 65.800m2 new productions, 31.800m2 broadcasting production programs 105.400m2, 30.000m2 staff facilities, parking 61.500m2, 15.000m2 services spaces plus a hotel, a visitor center and a large theater. But what does it actually say about architecture and China today? Diagonal columns grids have the same width exposed, but the depth varies according to the load, while the diagonals are all plate girders 1m x 60 cm, with the only variation in the thickness of the steel. The structure of the CCTV Headquarters, and the forces at work within it, is visible on its façade: a web of diagonals that becomes dense in areas of greater stress, looser and more open in areas requiring less support. Next, the analysis was repeated until the results were combined and all batteries were within allowable capacities.
