After the Great Hanshin-Awaji Earthquake, vibration control technologies for structures have been in great attention and the application and R&D for such technologies have been carried out researchers. Storey-installation type damper, such as elasto-plastic dampers and oil dampers, currently used in structures to mitigate their excessive earthquake responses. However, it is pointed out that the former has an weak point in reducing small amplitude of vibration such as traffic vibration and weak wind vibrations, and the latter needs an maintenance mainly for the oil leak. In this study, it aims at the research and development of the plastic flow damper which is the simple construction, the large damping capacity and maintenance free. In this paper, the dynamic load test results of the damper that was designed for 800kN loads are described.
