| Outline of Final Research Achievements |
Three types of structures, steel structures, reinforced concrete structures, and wooden structures were considered for various studies on damper installations and performance assessment. Loading tests on these frame subassemblies duplicated the realistic behavior. Also detailed analytical models were constructed to reproduce the behavior of these structures and parametric study was performed in order to understand the nonlinear behavior of these structures. In order to understand the ultimate performance of dampers, tests of four types of real scale dampers, steel damper, visco-elastic damper, viscous damper, oil damper were conducted, and their behaviors were reproduced by analytical models. Using the observation records obtained during the Great East Japan Earthquake, the real effectiveness of the damped buildings were examined. All of these knowledge has been implemented in the passive control design guideline manuals.
