Control of bridges using magnetorheological fluid (MRF) dampers and a fiber-reinforced composite-material column
Supplemental energy-dissipating systems for bride structures have been proposed to mitigate harmful effects of earthquakes. Controllable damping devices are among these systems. They can potentially provide immediate vibration control for structures subjected to destructive seismic motions. In response to these demanding needs, a theoretical and experimental study is performed to evaluate the response of a scaled-model bridge using magneto-rheological fluid (MRF) dampers. The scaled- model bridge is analyzed for its dynamic response to various inputs when MRF dampers are utilized to control the structure. In addition, a graphite/epoxy-concrete column is used in the scaled bridge structure, and its interaction with MRF damper is studied. Procedures and results for the theoretical and experimental testing of the MRF dampers and the scaled-model bridge are presented. MRF dampers proved to significantly improve the response of the structure.
