SIMPLE SEMI-ACTIVE CONTROL FOR BASE-ISOLATED BUILDING BY MR DAMPER

Abstract

Building structures subject to disturbances such as earthquakes and winds are required to insure safety and amenity. Semi-active control has the potential to solve this problem. A shaking table test has been performed on a three-story base-isolated structure using simple control system with MR damper. Its effectiveness is examined by comparing the experiment results with those for passive control. The authors compared the experiment result with the response analysis result. Conclusions are listed. (1) The simple control system of this paper is operating well. (2) The experiment result of semi-active control shows the safety and amenity effectiveness superior to the experiment result of passive control. (3) The response analysis result agree with the experiment result.
