N2 - This study involves vibration performance in footbridges by introducing a precise human body model. This model is adequately adjusted for considering the interaction between bridge and pedestrians on the footbridge. Dynamic FE program is developed to apply this model. The results from this program are compared to the responses computed by time-domain force model and experimental data. From this comparison study, it can be concluded that the dynamic responses from the analysis using human body model are larger than that of time-domain model, because of human-structure interaction. Finally, vibration serviceability of footbridge is estimated under crowd-induced excitation. The results showed that the human-structure interaction force and the inertial forces of human masses somehow affected the responses whole bridge.
