Abstract
Damping devices, which are properly designed and installed, are effective in reducing the working stress, force, and displacement etc. of bridge structures during an earthquake. In application of damping devices, it is necessary to realize the basic characteristics of each device in terms of velocity dependence before selecting a device, adequate modeling for dynamic response analysis and so on. Then presented in this paper are the characteristics of the cylinder-type damper, which is one of damping devices for bridge structures, and an application example to an existing arch bridge.
