| Outline of Final Research Achievements |
Development of counter measures to address the vulnerability issues of long-period structures subjected to long-period/long-duration ground motion is pursued in this research project. Materials regarding variations of supporting spring stiffness of the tuned viscous mass damper system that are useful for practical design is collected from the construction project at Akasaka icho-me leading to development of a general design theory and an experiment method for the system. Tentative design of a full-scale variable orifice damper and manufacturing of its prototype deformation detector parts are completed.
