Abstract

本論文では, 兵庫県南部地震で多くの被災例を残した既存の落橋防止連結板装置を改良する簡易な手段として, 連結ピンの周囲に高強度の積層繊維ゴムを巻いた緩衝ピンを提案した. ゴム緩衝ピンの効果を定性的かつ定量的に評価するため, 使用時レベルと終局時レベルの2段階に分け, それぞれに対する静的挙動および衝撃緩衝特性の検討を実験的に行い, 従来の鋼製ピンとの比較を行った. その結果, 使用時レベルでは荷重分散効果と衝撃緩衝特性に優れており, 終局時レベルでは最大耐力の低下が見られるが, 限界吸収エネルギーは増大することが認められた.

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.
