When completed in 2010, the GNTVT will be the world's tallest TV tower with a total height of 610 m. It consists of a main tower (454 m) and an antennary mast (156 m). The GNTVT will be operated in 2010 to broadcast the 16th Asian Games, which will be held in Guangzhou from November 12 to 27, 2010. It will used for office space and for entertainment, catering, tour, and mainly the transmission of television and radio programs.

As illustrated in Figure 1, this structure comprises a reinforced concrete interior tube and a steel external tube. There are some floors and four levels of connection girders linking the interior tube with the external tube. The external tube (see Figure 2) consists of 24 concrete-filled-tube (CFT) columns uniformly spaced in an oval configuration and inclined in the vertical direction. The dimensions of the oval decrease from 60 m × 80 m at the ground to the minimum of 20.65 m × 27.5 m at the height of 280 m before increasing to 40.5 m × 54 m at the top of the tube (454 m). The interior tube (see Figure 3) is also an oval with constant dimensions of 14 m × 17 m, while the centroid differs from that of the external oval. This hyperbolic shape makes the structure interesting and attractive from an aesthetics perspective, it also makes it mechanically complex. A sophisticated long-term structural health monitoring (SHM) system consisting of more than 700 sensors of 16 different types has been designed and is being implemented to monitor the GNTVT during both construction and service stages.
