Introduction of Changzhou Modern Media Center Construction Project?

With the progress of science and technology, there are more and more high-rise buildings in cities. However, taller super-high-rise buildings are rare, and then the detailed information about global super-high-rise buildings brought by Zhong Da Consulting is given.

Wenzhou World Trade Center Building is located in plots 8 and 9 of Jiefang South Road, Wenzhou City, bordering Jiefang South Road in the east, Maanchi Road in the south and Business Plaza in the northwest, with 68 floors above ground, 4 floors underground and 72 floors underground. The above-ground height is 333 meters, with an area of 3 1 000 square meters, the above-ground construction area exceeds 654,380+0,800 square meters, the underground construction area exceeds 70,000 square meters, and the total construction area exceeds 250,000 square meters. The scale of the building is equivalent to fifteen Wuma Streets. It is a comprehensive business office building integrating business, office, sightseeing, entertainment, catering and conference functions.

Structure of Wenzhou World Trade Center Building

subsurface structure

Due to the limitation of building height, the basement adopts a flat floor system, and other floors are beam-slab structures.

Above ground structure

The main structure of Wenzhou World Trade Center Building adopts tube-in-tube structure composed of reinforced concrete outer frame tube and core tube. For the tube-in-tube structure, due to the requirements of the use function, there is inevitably a structural conversion problem. According to the architectural design and the requirements of the owner, the structural transfer floor starts from the 10 floor. Because the structure belongs to high-rise transfer story, the traditional beam transfer story cannot be adopted, so the column transfer story is relatively direct and uniform, and all structural transfers are completed at 15 floor.

Due to the requirements of buildings and equipment, the height of coupling beams in the core tube of the main building is strictly controlled. In order to ensure the "strong shear and weak bending" characteristics of coupling beams under horizontal load, some coupling beams of some floors adopt rigid concrete beams. According to the stress requirement, the steel beam in the rigid concrete beam should be anchored in the concrete wall at both ends, but the horizontally anchored steel beam intersects with the vertical reinforcement of the embedded column in the wall, which is difficult to solve in construction. Therefore, after the rigid steel beam enters the edge of the concealed column for nearly 20mm, the reinforcement is creatively replaced by equal strength, which solves the anchoring construction problem of the rigid steel beam in the concealed column well.

The structure of Wenzhou World Trade Center Plaza basically adopts reinforced concrete frame structure, and the seismic grade of the structure is Grade II. Because the two districts need to cross a municipal road, a street crossing corridor is set up, and the beam span here is nearly 24m. Therefore, the post-tensioned bonded concrete prestress technology is adopted, and the prestressing tendon curves are all set according to quadratic parabola, which greatly reduces the beam height, provides a more reasonable clear height of the building and achieves better architectural effect.

Wenzhou World Trade Center Building

roof structure

At the top of Wenzhou World Trade Center Building, there is a 60-meter-high steel structure, which is symmetrical on all sides. The glass segment gradually inclines and retracts, and with the gradual divergence of the metal dividing line, it presents a natural growth and development trend. There is also a lightning rod more than 20 meters high at the top.

The roof steel structure adopts spatial rectangular steel tube truss structure, which supports the required shape of the building outside the concrete skeleton. Steel structure has load-bearing joints on each floor of concrete structure, which are hinged.

The building is divided into two parts: the podium and the tower. The podium is a large department store with 40,000m2 from the negative 1 floor to the seventh floor. The eighth floor is 9 Mi Yue, with a height of 2,500m2, which is used as a press release and exhibition center. The tower 1 floor to the third floor is about 20,000 square meters, which is the world's top boutique shopping mall, and the fourth floor to the fifth floor is about 1.5 million square meters, which is a high-end brand store. The sixth and seventh floors are about 1.0 million square meters, with swimming pool, sauna, gym, cigar bar, entertainment center, Chinese and western restaurants, Japanese and Korean cuisine, etc. Floors 8 to 5 1 are 5A-level pure-word buildings. The 52nd-65th floors are five-star hotels, the top 66th-67th floors are about 2,500 square meters of aerial coffee bars, and the 68th floor is about 2,000 square meters, overlooking the whole city. In addition, the basement of the first floor of the building is equipped with a sunken shopping mall, and the second to fourth floors are motor vehicle parking garages, which can accommodate more than 1000 vehicles at the same time.
