Equations of motion have been proposed to predict the horizontal girder response of footbridges induced by pedestrians. The equations take into consideration the ratio of the pedestrians' horizontal force to their weight, the pedestrian density, the proportion of synchronized pedestrians, and the pedestrians' response to large-amplitude vibrations. The equations are then applied to two cable-supported bridges that have suffered from horizontal vibration. The predicted horizontal girder response agreed well with the measured girder response of these bridges, which verifies the validity of the prediction method.
