Abstract
This paper analysed seismic reducing capacity of MR damper, a very new damper, with the relative small power and the response rate is very quickly. Structural model was used in this study was three-storey steel frame under the four actual earthquakes. El Centro, Hachinohe, Kobe, Northidge and the Artificial Earthquake: A quakeEarth. Seismic reducing effect of structure was calculated relying on five algorithms: Clipped-Optimal with full state feedback of displacements and velocities, HZ/LOG with acceleration feedback in assosiation; Proposed Fuzzy Control; Gain-Scheduled Fuzzy Control and Self-Tuning Fuzzy Control with Simulink tool of Matlab. Through this studied result, MR damper with Self Tuning Fuzzy Control Algorithm has brought very good seismic reducing effect as that structure was influenced by earthquake.
