What is Guang Zhouta's introduction?
The construction of Guang Zhouta is a milestone for Guangzhou and even China. Before this, many foreign tourists may only know that China has Beijing and Shanghai, but they don't know that there is Guangzhou, and Guang Zhouta is a representative building for those who are not familiar with Guangzhou.
design feature
The whole tower of Guang Zhouta is a hollow steel frame, with 24 steel columns twisted counterclockwise from bottom to top, and the cross section of each member is changing. The columns, beams and supports of steel frame tube are all in a three-dimensional inclined state, and the twisted steel frame tube is thick from top to bottom and thin in the middle, which brings challenges to the processing, manufacturing, installation, construction survey and deformation control of steel structure. The steel frame tube alone has 24 steel columns, 46 groups of ring beams and 1 104 diagonal braces.
Because of the material difference between concrete core tube and steel structure outer frame tube in Guang Zhouta, the settlement of floor beam and outer frame tube is inconsistent. In order to adjust the correctness of the relative position between steel members and the main structure, many nodes control the accuracy of the relative position of steel columns through three-dimensional coordinates.
