VIBRATION CONTROL SYSTEM OF A NINE-STORY BUILDING STRUCTURE THAT RECEIVES SEISMIC LOAD WITH SEMI-ACTIVE TUNED MASS DAMPER SYSTEM
Earthquake vibrations that can cause damage to building structures have prompted the development of Semi-Active Tuned Mass Damper (SATMD) vibration control technology. SATMD consists of mass, stiffness, and a damper in the form of a magnetorheological (MR) damper. The MR damper contains magnetorheol...

| Summary: | Earthquake vibrations that can cause damage to building structures have prompted the development of Semi-Active Tuned Mass Damper (SATMD) vibration control technology. SATMD consists of mass, stiffness, and a damper in the form of a magnetorheological (MR) damper. The MR damper contains magnetorheological fluid that can change its phase from liquid to semi-solid within milliseconds by applying a specific magnetic field. The impact of using SATMD is investigated by applying it to a nine-story building subjected to the seismic vibrations of Kobe (1995), Borah Peak (1983), and Kern (1952) earthquakes, which are spectrally matched. The structure is evaluated in two-dimensional form and analyzed linearly. The response of the multi-degree-of-freedom structure is obtained through numerical analysis. The structural responses without SATMD and with SATMD are compared in terms of RMS deformation, maximum deformation, and inter-story drift. The responses of the structure with SATMD placed at different locations are also compared. These comparisons are presented in terms of effectiveness. |
