This research proposes a new bridge restrainer system with fiber reinforced rubber-rolled pin and examines the effect of it for the shock absorber device. First, static and impact loading tests were performed in order to examine the mitigating effect in the elastic range. Second high speed loading test was performed to compare the energy absorbing capacity of rubber-rolled pin system with steel pin system. Finally, numerical simulations of static behavior and dynamic response of rubber-rolled pin were carried out in the elastic range. The following results were obtained from this study :1) Rubber-rolled pin could decrease about 1/4 the responding strain of restrainer plate compared with the case of steel pin system.2) The ultimate limit displacement and energy absorbing capacity of rubber-roiled pin were about 20% larger than those of steel pin system.3) A simple hyper-elastic model is applicable to the fiber reinforced rubber and it can simulate well not only static behavior but also dynamic response in the weight dropping test.

本研究提出一种新型的纤维橡胶滚销式桥梁限位系统，并探讨其对桥梁之减震效果。首先，进行静态和冲击载荷测试，以检查在弹性范围内的缓解效果。进行了第二次高速加载试验，比较了橡胶销轴系统和钢销轴系统的吸能能力。最后，在弹性范围内对橡胶滚轧销的静态行为和动态响应进行了数值模拟。研究结果表明：与钢钉系统相比，橡胶销可使约束板的响应应变降低约1/4;橡胶销的极限位移和能量吸收能力比钢钉系统提高约20%;纤维增强橡胶具有简单的超弹性模型，不仅能很好地模拟静力性能，而且能很好地模拟落锤试验中的动力响应。
