Abstract

It has been increasingly recognized that the field monitoring data from structural health monitorina (SHM) svstems deployed on lona-span bridges and high-rise buildings are very helpful to verify design assumptions and parameters, alarm abnormal loading and response, assess structural integrity after disasters and structural serviceability during extreme events, issue early warninas on structural damage/deterioration, and instruct the design of similar structures in future. Taking the instrumented Tsing Ma (suspension) Bridge with a main span of 1,377 m and the instrumented Canton Tower of 600 m high as engineering paradigms, this paper demonstrates how the SHM data benefit structural condition assessment A systematic framework for condition assessment of instrumented bridges making use of long-term monitoring data of strain is first introduced and demonstrated using the monitoring data obtained from the Tsing Ma Bridge. Then the monitoring data acguired from the Canton Tower durina over ten near-field and far-field earthguakes are presented to show how to identify the modal properties on-line by utilizing the measured seismic response data and how to assess post-earthquake structural condition of high-rise buildings with the use of monitoring data.
