In this research an experimental study was carried out to decrease the damage caused by the collision of bridges as earthquake load was added. For the experiment, we designed a model of successive bridge composed of a reinforced concrete bridge top and I section steel. As for damper, we ourselves designed and produced a MR damper of 30 KN. The result proved that the MR damper of our own design was effective to prevent the successive bridge model from colliding.
