Abstract
Vibration serviceability assessment of footbridges requires a reliable probabilistic model for multi-pedestrian loading and a suitable approach to take into account human-structure interaction. In the present paper, the human-induced dynamic response of footbridges is analysed using a mode superimposition approach. The power spectral density functions of the modal loads are defined according to an equivalent spectral model, and suitable equivalent dynamic properties of each mode are estimated for the human-structure coupled system. The validation against the Eeklo Footbridge benchmark dataset confirms the reliability of the proposed approach.
