Paper Title:
MRF Absorber Damping Control for Building Structural Vibration Response by Means of Genetic Optimum Algorithm
  Abstract

A similar structure model has proposed for three-storey building structure based on similarity theory, thus differential equations are established for the 4-DOF vibration system. According to the vibration characteristics of resultant structures, the mass, stiffness and damping coefficient are obtained by using genetic optimum algorithm, and then an MRF absorber has been designed and fabricated based on the optimized absorber parameters obtained. Furthermore, a set of semi-active vibration control testing system for building structures is designed and a pilot study on the damping effect of the MRF absorber has been performed. By adjusting the shock absorber damping force, inertia force and movement frequency synchronously against the external excitation force, the installed MRF absorber could significantly reduce the vibration amplitude of the considered building structure, clearly evidencing the damping effect of the MRF absorber.
