Paper Title:
Monitoring Dynamic Characteristics for a Supertall Structure under Different Loading Events
  Abstract

The Guangzhou New TV Tower (GNTVT), completed its construction in May 2009 in Guangzhou China, is a super tall tube-in-tube structure with a total height of 600m. A complicated structural health monitoring (SHM) system consisting of over 700 sensors has been implemented to the GNTVT for both in-construction and in-service real-time monitoring. This implemented SHM system has monitored the structural responses of the GNTVT after having completed its construction under different loading events (the typhoon, the earthquake and normal wind loading conditions). Firstly, the time history and PSD of the acceleration response under different loading events have been compared. Secondly, the modal properties (modal frequencies, mode shapes, and damping ratios) of the structure under different loading events have been identified. The results of this paper supply some references for better understanding the dynamic characteristics of supertall under different loadings.
