METHOD FOR EVALUATION OF THE FORCE IN LONGITUDINAL CABLE SEISMIC RESTRAINERS
|

| 抄録（英）： |
In this paper, the magnitude of the force arising in longitudinal cable restrainers during earthquake is investigated. The study was carried out by numerical simulation on two models; one of a five-span continuous bridge and another of a single span bridge, both on rubber bearings. The cumulative force arising in the restrainers after failure of the bearings was found to grossly exceed the current design guidance value. In absolute terms, the maximum force in the restrainers was in the order of the weight of the upper structure for the continuous bridge, and three times the weight for the single span bridge. A practical method based on energy conservation for computing the force is proposed.
