Abstract

This paper presents the human-induced vibration assessment of the Monash University pultruded Glass Fibre Reinforced Polymer (GFRP) laboratory footbridge to investigate the suitability of current vibration serviceability design rules for such structures. This paper reports the results of the experimental modal testing of the footbridge. The experimental results were calibrated with a Finite Element (FE) numerical model. Further, a novel sequence of human walking trials were performed to assess the vibration performance under real loading conditions. Modelling of human-induced vibration response of the footbridge was also carried out. Peak accelerations from measurements and simulations are compared. The results highlight that the current guidelines are not well suited for considering vibration serviceability under human-induced vibration of footbridges.
