STRUCTURAL HEALTH MONITORING OF SUPERTALL STRUCTURES:AN ENGINEERING PARADIGM AND TECHNOLOGY SHOWCASE
The Canton Tower (CT) is a supertall structure with a total height of 610m. During its construction, a sophisticated long-term structural health monitoring (SHM) system consisting of more than 600 sensors of sixteen types has been designed and implemented by The Hong Kong Polytechnic University for real-time monitoring of the structure at both in-construction and in-service stages. It provides a unique engineering paradigm for monitoring and assessing high-rise structures using sensory technology, and a test-bed for SHM benchmark study of supertall structures with use of real-world monitoring data. The present paper describes the design, implementation, operation, and management of this lifecycle SHM system, and the integration of the SHM system with the vibration control system and the renewable energy technology deployed on the CT. Monitoring data of the CT during a number of typhoons and earthquakes (including the recent devastating Japan Earthquake) are presented and an SHM benchmark problem with the instrumented CT being a host structure is outlined.
