Abstract
This paper deals with a simple formula approximating maximum lateral response of pedestrian bridges caused by synchronized walking by pedestrians. Numerical simulations were carried out for the pedestrian bridge model with the lateral frequencyof 0.6-1.0 Hz in order to grasp the lateral response characteristics of pedestrian bridges. In addition, several pedestrian bridges suffered pedestrian-induced sways were used to verify the validity of the proposed formula. It was ascertained that the evaluation value based on the proposed method developed in this paper could be fairly in good agreement with the measured value when pedestrians walked in step with the bridge's resonant frequency.
