Abstract
Although introduction of vibration control systems for bridges have advantages in terms of both seismic performance and construction cost, seismic design method of the bridges utilizing dampers is still developing. The purpose of this study is to promote the design method of bridges utilizing dampers. This paper describes the result of shaking table tests of bridge models with friction slip dampers. Followings are found. (1) It was observed the dampers and the pier models exhibiting nonlinear behavior resisted to the earthquake action in cooperation. (2) It is found that the friction slip damper is effective to reduce the response displacement. (3) The contribution of the damper to the each level earthquake is determined. Furthermore, numerical modeling of the damper is developed through the dynamic analysis.
