| Research Abstract |
The objectives of this research program are ; to investigate performance limitations of various passive control systems considering the restraints posed by the control devices as well as frames, and ; to proposed the unified design methodology to evaluate/design the systems based on simplified response prediction method. In order to fulfill the objectives, careful dynamic experiments on the devices and systems were conducted, and the results utilized to create both detailed and simplified device analysis models, which were used to formulate and evaluate the unified design methodology. The study items are summarized below:
Deformation-Dependent Type : Formulation and validation of equivalent linearization technique, Tests of low-cycle fatigue characteristics of steel shear panel dampers, Tests and analyses of friction dampers, Evaluation of response reduction rule, Performance evaluation and design methods for single- and multi-story buildings having deformation-dependent type devices.
