The last few decades new trends in the design of pedestrian bridges have resulted lighter and more slender structures. This leads to a reduction natural frequencies increased flexibility, thus greater possibility for structures become exposed excessive vibrations caused by pedestrians. lager amplitudes occur if pace frequency excitation load approaches one footbridge. vibration high proportions...

Due to the high strength-to-weight ratio of fibre reinforced polymers (FRPs), human-induced vibration problematic remains as a subject be fully comprehended in order extend use composites Bridge Engineering. Thus, this paper studies an ultra-lightweight FRP footbridge, which presents excessive vertical vibrations when fourth harmonic walking pedestrian is synchronised with structure’s fundament...
