When the strong earthquake occurs and a bridge suffers the longitudinal impact, a superstructure and abutments of a bridge will collide. There is a spatial gap between superstructure and wall of abutment and this gap may effect to accelerate collision speed between them. Then, in this paper, effect of shock-absorbing device to softening the collision is investigated in the cases of simple and continuous girder bridges. And the effect of stiffness of shock-absorbing device, laying-gap length and back-fill ground of a abutment to soften the collision response, is analyzed. Moreover, influence by laying-gap length and an abutments of back-fill ground when colliding was examined.
