As a result, more and more elevated highways, usually long piers, have been erected in urban platforms to ease urban traffic pressures. However, the high traffic volume of such highway bridges can cause significant vibration. To study the effects of vibration caused by bridge traffic, this study monitored the acceleration due to moving vehicles of an isolated bridge for 24 hours. The fast Fourier transform method and the system implementation method are then used to analyse the acceleration measurements and thus to calibrate the system parameters of the bridge and the building. Besides, the displacement from the deck to the pier and the deck acceleration were measured to investigate how vehicle transport affects the structural performance of the deck and pier. The results can be used as a reference for improving vibration problems caused by bridge traffic in the future. ? 2020 IOP Publishing Ltd.
