Abstract
The Guangzhou New TV Tower (GNTVT) with a total height of 610 m is the landmark of the Guangzhou city in China and the tallest TV tower in the world. It comprises a 454 m high main tower and a 156 m high antenna mast. The main tower is a tube-in-tube structure consisting of a steel lattice outer structure and a reinforced concrete inner structure. The antenna mast is a steel structure founded on the top of the main tower. To ensure the safety during construction and the operational performance during typhoons and earthquakes of this challenging structure, a sophisticated long-term structural health monitoring system consisting of about 800 sensors has been implemented for on-line monitoring at both construction and service stages. In the meanwhile, a hybrid mass damper control system is installed on the main tower and two tuned mass dampers are suspended on the antenna mast for suppressing wind-induced vibration of GNTVT. This paper outlines the structural health monitoring system and the vibration control system for GNTVT and their integration.
