This study is focused on two types of shock absorber of a bridge restrainer system: one is fiber reinforced rubber-rolled pin and the other is fiber reinforced rubber-rolled pin with steel pipes at the inner and outer edge of the rubber. First, applicable limit of the shock absorber was defined and 3D FE analysis was conducted to determine equivalent imp act condition under using a drop weight impact machine. Second, single and repeated impact tests were performed to compare the mitigating effect and the damage of a pin. As a result, it was confirmed that the elastic limit and mitigating effect were quantitatively evaluated by comparing of two types.
