Abstract

A new bridge restrainer system with rubber-rolled pin is proposed for the great earthquake. First, the static and high-speed loading tests are performed for the bridge restrainer system with and without rubber, respectively. Second, it is found that the rubber-rolled pin can absorb the large strain energy by cutting the fiber involved in the rubber and , as such, it has the large ultimate displacement until failure. Therefore, it is confirmed that this new bridge restrainer with rubber-rolled pin will be useful for the great earthquake. 1 Introduction As one of the failure modes in the highway and railway bridges in Kobe earthquake, January 1995, the failures associated with the bridge restrainers were seen in many pla
