How many meters and floors are there in Kunming Wanda Twin Towers?

Kunming Wanda Twin Towers has 67 floors above ground and 3 floors underground, with a height of 307 meters.

The Kunming Twin Towers are located in the Himalayan earthquake zone. The complex stratum structure and the overweight steel structure of the towers themselves have brought severe challenges to the construction. According to the investigation, the depth of the foundation pit of the Twin Towers is16m, and the depth of the pit in the pit is 23m, both exceeding the standard depth of Yunnan Province by 8m.

2015 65438+1October 18 The first 307-meter twin towers in China were capped, making it the tallest building built in Yunnan at present. The investment of Kunming Twin Towers is as high as 3 billion yuan.

Extended data:

The first 307-meter core tube of China Twin Towers, built by Southwest Branch of China Construction Second Bureau, was capped in Kunming, which is the tallest building built in Yunnan at present.

The tallest building is the wanda plaza Twin Towers and the Kunming Pan-Asia Financial Industry Building, which are located in the Western Hills. 2065438+Construction started in September 2003, with an investment of 3 billion yuan. The twin towers are designed with 67 floors above ground and 3 floors underground, with a single-storey height of 4. 1 m. The design and construction of the two towers at the same time, from civil engineering to steel structure and external curtain wall construction, are all carried out by two units at the same time, with the 307-meter core tube capped at 50 1 day.

The foundation pit of the Twin Towers is as deep as 16 meters, of which the pit depth in the pit is 23 meters, which is 8 meters beyond the standard depth in Yunnan Province. The depth of the foundation pit of this project has also set a record for the deepest foundation pit in Yunnan Province.

The engineering structure is a steel structure with steel reinforced concrete core tube and outer frame, and the whole structure is made of seismic reinforcement and C60 high-strength concrete. The steel content of a building is 30,000 tons, and the steel content of each standard floor is about 500 tons, which is four times that of the known all-steel structure buildings in China. It is a rare and difficult steel structure building in similar projects in China.

Earthquakes such as Ludian, Pu 'er and Jinghong occurred frequently in 20 14. During the construction process, the twin towers felt an obvious earthquake, and the swing range at a height of 200 meters could reach 60 to 80 cm.

The twin towers were designed according to the seismic fortification of eight degrees, but they were conservatively raised to eight and a half degrees during construction, and the whole structure was made of seismic steel bars. In the case of continuous earthquakes, China Construction Second Bureau successfully applied the super-high-rise comprehensive construction technology in multi-earthquake areas to deal with earthquake force majeure, which strongly proved the structural safety of the project.
