    Abstract

    Magneto-rheological fluid dampers (MR dampers) have recently been designed to control the response of civil engineering and building structures because of their large force capacity and controllable force characteristics. To enable them to control structural responses, the dynamic characteristics of structures need to be clarified. This paper discusses the design of MR dampers with a bypass orifice mechanism and verifies their performance by means of dynamic tests and dynamic analytical models. Their dynamic characteristics are investigated experimentally to compare the performance of two different magneto-rheological fluids. One is developed by the Lord Corporation and the other is newly developed in Japan. The effectiveness and validity of MR dampers with a bypass are discussed on the basis of these results.
