Prove dinamiche su strutture controllate con dispositivi magnetoreologici (MR)

In this paper a shaking table experimentation is presented, which refers to a coupled adjacent structures configuration, that may be used in civil and industrial applications. The physical model is a 1:5 scaled coupled structures. The first structure is a 4-story model, while the second structure is a 2-story model. The introduction of the magnetorheological (MR) device between the adjacent structures is shown to be able a viable method to protect the structures from seismic excitation. The MR damper is applied as passive and semiactive device. The results confirm good performance of the passive and semiactive control system in reducing the response of both structures. Finally a mathematical model of the structures and the device has also been identified and validate.
