Guangzhou TV and Sightseeing Tower, China

Information Based Architecture (IBA)

The hyperboloid structure is in the form of a twisted and tapering tube. The outer steel-framed structure consists of 24 steel columns with concrete in-fill, a series of 46 oval-shaped rings of different sizes and single-direction diagonals throughout the structure. Over 40,000t of structural steel (including the mast) will be used for the project.

“The position of the core in turn is affected by the desire to have a rotating restaurant at the top of the building. On top of this, any change in the waist size results in a change in density of the structure altering the wind resistance. All these issues affect the amount of structural steel needed to create a stiff structure. This makes this building an example of a complex structure for which intensive studies were done in order to come to an optimised result.”
