Abstract

This paper is concerned with a new practical identification algorithm for all physical model parameters of a multi-story structure installed with an MR damper between a ground level and first floor. By using not only acceleration measurements of ground and all stories but also the MR damper force, the proposed method can directly give damping and stiffness parameters as well as mass parameters of all floors. Optimal weighting on each mode information is also proposed to improve the physical parameter estimation errors. Validity of the proposed algorithm is investigated in numerical simulation with application to structure health monitoring, and experimental study dealing with vibration isolation of a simple structure with an MR damper installed.
