Abstract / Description of output

Indirect Structural Health Monitoring (iSHM) for bridges typically utilises motorised vehicles. This project explores the feasibility of using bicycles as exciters and sensor carriers for identifying bridge modal parameters. Using field-gathered data, the visibility of bridge characteristics in the moving sensor data is demonstrated using data gathered simultaneously from the moving bicycle and the subject bridge. A com- parison is made to bridge dynamic properties estimated from other load- ing types. The possible pollution of recorded signals due to human-bicycle interaction dynamics is considered. The concept of exploiting pedalling harmonics to enhance the response amplitude of specific bridge modes of interest is introduced.
