Abstract

The Guangzhou New Television Tower (GNTVT), currently being constructed in Guangzhou, China, is a supertall structure with a height of 610 m. This tube-in-tube structure comprises a reinforced concrete inner tube and a steel outer tube adopting concrete-filled-tube columns. A long-term structural health monitoring (SHM) system consisting of over 600 sensors has been designed and is being implemented by The Hong Kong Polytechnic University to GNTVT. This monitoring system is one of few SHM practices that integrate in-construction monitoring and in-service monitoring. It is also designed to perform a special function of verifying the effectiveness of vibration control devices to be installed on the tower. By taking this monitoring system as a paradigm, a SHM benchmark problem for high-rise structures which uses real-world data acquired from a full-scale structure is being developed. This paper describes the design and implementation of the SHM system for GNTVT and preliminary analysis results of the monitoring data from this system.
