This study focuses on dynamic behaviors of simply supported beams, especially, vertical displacements. Based on moving load model, the displacement is estimated by response superposition. The displacements tend to increase as load velocity increases except under resonance velocity and show very large values under resonance velocity. Therefore, we should investigate the resonance between train and structure.
