In order to research into the dynamic response of a steel box-girder continuous beam footbridge excited by a synchronised human stance excitation, a in-situ test and a code comparison were conducted. Sixteen model 891-B accelerometers of vertical, horizontal and lateral directions were instrumented on the bridge and the vibration signals were aqcuired at a sampling frequency of 512 Hz. The acceleration data were transformed into frequency domain to find out the fundamental frequency of the bridge, and the frequency weighted root-mean-square acceleration data were analysed to evaluate the bridge’s vibration serviceability under synchronised human excitation. Further more, the international standard of BSI5400, Bro2004, EN1990, and ISO10137 were applied to the aquired acceleration data to compare their applicability. The results indicate that the dynamic response of the footbridge will not invite uncomfortableness of the pedestrians.

The influence of the higher order modes of vibrations on the dynamic response of a suspension bridge is studied for two cases of loading. The first case is when the bridge is subjected to wind loading on the suspended cables and the bridge deck. The second case is when the bridge is subjected to a moving load on the bridge deck. The dynamic responses of the bridge deck and the suspended cables considering some higher order modes of vibrations are compared with the bridge response when it is modeled by the first dominant modes for each case of loading. It is shown that the influence of the higher order modes when the suspension bridge is subjected to wind loading is more significant than in the case when the bridge is subjected to a moving load. Therefore, it is recommended to investigate the influence of some higher order modes on the dynamic response of the suspension bridges and not always to depend on the response estimated from the first dominant modes of vibration.
