ABSTRACT
This paper reviews the current research status of active/semiactive vibration control of cable-supported bridges and explores some implementation issues. Although active control of cable-stayed bridges has been proposed at the end of the seventies, control of long-span bridge structures has not been studied to the extent that tall buildings have. Studies of applying active control to cable-supported bridges have been revived in the last decade, mainly focusing on active tendon control and decentralized control techniques in terms of simple structural models. Research of active/semiactive seismic response control in terms of detailed bridge models and using various control devices has only recently been considered by the ASCE Task Committee on Structural Control Benchmarks. Some control-design issues such as control oriented modeling and control device adoption for cable-supported bridges are also addressed in this paper.
