Abstract
In this paper, frequency response analysis of a tuned liquid column damper using magnetic fluid (MF-TLCD) based on a linearized method was presented. An MF-TLCD alters the natural frequency of the magnetic fluid column that forms the resident liquid inside the MF-TLCD by applying a magnetic field. The interaction equations of motion under a harmonic type of loading for SDOF damped structure and liquid surface motion in a MFTLCD were expressed. The damping term induced by liquid flows and the magnetic force term were linearized to derive analytical solutions. The analytical results were compared with experimental results.
