Abstract

Many bridges were severely damaged by the Hyogo-ken Nanbu Earthquake. Talking this lesson into account, the fundamental design concept was changed so that bridge might be prevented from falling down by the equivalent earthquakes. Many researchers have studied the shock absorber for bridge restrainer system. In this study, the static compress test was performed for the various type of the laminated fiber reinforced rubber, which will be expected to be of use as a shock absorber in bridge restrainer system. The following results are obtained: (1) The optimum shape to be used as a shock absorber is the cubic. (2) An empirical equation for initial yield load of laminated fiber reinforced rubber is proposed for the various cube and cylindrical specimens.
