This main purpose of this study is to measure the vibration induced by the passing train and build model by ETABS. The input data are the acceleration time histories that recorded at the location of measurement. The results of the experiment and numerical analysis will compared with each that make the model be accurated. Finally, the structure modal set with TMDS by ETABS may suppress the vibration of structure. The principle of damping vibration is that tunes TMD into the natural oscillation frequency of structure in order for inner material within TMD to vibrate in an opposite direction to an external force. This process allows vibrational energy to be absorbed by decreasing vibration of structure as a result.
