The purpose of this paper is to study the effects of the restrainer gap and the rubber-type shock absorber on the peak response of the existing long-span girder bridge that has bearings vulnerable to strong earthquake ground motion. The restrainer and the stool with the sliding plate are proposed to be installed as the backup bearing in case of the existing bearing failure. The seismic response analysis considering the existing bearing failure is conducted. The study shows that the restrainer gap enables the peak response displacement of the fixed-side column to decrease because of the seismic isolation effect, and that the shock absorber can reduce the peak response reaction forces of the restrainer.
