Demo-application of shape memory alloy devices: the rehabilitation of the S. Giorgio Church bell tower
This paper describes the rehabilitation of the S. Giorgio Church Bell-Tower (Trignano, Municipality of S. Martino in Rio, Reggio Emilia, Italy), completed in September 1999. This masonry building, ser...
Experimental study on fuzzy logic vibration control of a bridge using fail-safe magnetorheological fluid dampers
This study presents a semi-active vibration control of a scaled two-span bridge structure. Magneto-rheological fluid dampers are utilized as the semi-active energy absorbing devices, and a bridge vibr...

Thispaper presents a formulation for the optimal design of MRdampers. MR materials are suspensions of magnetically soft particles ina hydraulic medium. The application of intense magnetic flux tothese materials gives rise to a fibrated microstructure which, whensheared, resists flow with yielding and viscous mechanisms. The yieldstress is controllable by the magnetic field and is completelyand immediately reversible when the field is removed. Controllable MRdampers utilizing MR materials entails a magnetic circuit consisting ofa coil and low-permeability magnetic material to contain and guidesthe magnetic field.
