| Research Abstract |
In this research project, the following results are achieved. (1) New precision model reduction method is proposed for optimal placement of vibration control devices, i.e. hysteresis damper or viscoelastic damper. (2) New physical parameter identification method is proposed which can identify stiffness or damping performance of vibration control structure based on response records. (3) Optimal damper placement method for vibration control structure with nonlinear damper is proposed using reduced model. Robustness evaluation of vibration control structure can be performed based on the optimal design.
