The Canton Tower (formerly named Guangzhou New TV Tower) located in the city of Guangzhou, China is a super-tall structure with a total height of 610 m. To ensure safety and serviceability of this landmark structure during construction and operation, a sophisticated long-term structural health monitoring (SHM) system consisting of over 700 sensors of 16 types has been designed and implemented for real-time monitoring of the structure at both in-construction and in-service stages. It provides an excellent opportunity to on-line monitor dynamic responses of super-tall structures during earthquakes and look into seismic performance of super-tall structures with the monitored data. Since 2008, the SHM system deployed on the Canton Tower has successfully monitored seismic responses of the structure during over ten earthquakes, including the Wenchuan Earthquake and Japan Earthquake. This paper presents the monitoring data of the instrumented Canton Tower during typical earthquakes, and outlines how to identify modal properties using the measured seismic response data and how to assess post-earthquake structural condition using the monitoring data acquired before, during and after an earthquake.
