Paper Abstract

A smart bridge model was proposed for active control on strength and vibration by changing material properties of shape memory alloy embedded in the bridge structure using TiNi/acrylic composite. A systemic experimental study was carried out to investigate the self-strengthening effect by shape recovery of pre-strained TiNi wires as well as vibration control by stiffness changing with direct electric heating method. The deflection and vibration responses are measured by electric strain gages affixed on the bridge floor on which the model train goes through. From these results, we know the smart bridge model of composite material beam has not only been able to reduce the vibration response, but also change the frequency of the structure. The damping and vibration control for the bridge model is confirmed by the measurement.
