Vibration Serviceability of Footbridges and Its Mitigations

Abstract

This article presents the vibration serviceability problems of footbridges and its mitigations. There areseveral newly designed and constructed footbridges over the world known to have vibration problems andsome of them are presented herein, both vertical and horizontal vibration. Then, the mechanisms of vibrationgeneration due to pedestrians are explained. The guidelines for bridge designers are subsequently given inorder to prevent, as well as mitigate the excessive vibration problems. Finally, vibration mitigation measuresare also given.
