Abstract: The Guangzhou Television and Sightseeing Tower (GTST) located in Guangzhou, China, is a supertall structure with a total height of 610 m. One of the outstanding features of GTST is its 156 m high antenna mast founded on the top of the main tower which is a 454 m high tube-in-tube structure. The lower part of the antenna mast is a steel lattice structure and the upper part is a steel box structure. In view of the slenderness of the antenna mast as well as its extreme high erection location, a long-term structural health monitoring (SHM) system is being implemented for the antenna mast to watch its structural condition, especially the stability and whipping effect. This SHM system comprises anemometers, tiltmeters, accelerometers, and fiber optic sensors, totaling nearly 90 sensors in number. In addition, GTST is also designed with a hybrid control system with the intention of mitigating wind-induced vibration of the main tower. As operation of this control system requires the structural conditions as input, a data acquisition system is being implemented by the authors to feed the acceleration, velocity and displacement information to the control system. This paper briefs the SHM system for the antenna mast and the data acquisition system for the hybrid vibration control of the main tower.
