Abstract
This paper proposes a new bridge restrainer system with fiber reinforced rubber-rolled pin and examines the efficiency of it for the shock absorber device by the experimental approach. First, static and impact loading tests were performed in order to examine the mitigating effect in elastic range. Second, high speed loading test was performed to compare the energy absorbing capacity of rubber-rolled pin system with steel pin system. It was confirmed that the rubber-rolled pin could decrease about 1/4 the responding strain of bridge restrainer plate compared with the case of steel pin system. In addition, it was also found that the ultimate limit displacement and energy absorbing capacity of rubber-rolled pin were larger than those of the steel pin system.
