Abstract

Magnetorheological (MR) dampers have emerged as one of the most promising devices to suppress cable vibration in cable-stayed bridges, owing to their attractive features of minute power requirement, controllability, fail-safe operation, rapid response and low environmental sensitivity. While possessing controllable damping capability, the MR dampers are unable to monitor cable vibrations for implementing semi-active closed-loop controls, and are used merely as adjustable passive dampers in an open-loop mode in the current practices. Hence, a novel self-sensing MR damper system with an embedded PZT sensor has been tailor-made for real-time cable vibration control. Its laboratorial fabrication and characterization are to report.
