## Abstract A study is conducted to investigate the effectiveness of attaching to cableβstayed bridges resonant appendages with a relatively small mass and a high damping ratio as a means to reduce their response to earthquake excitations. The study is based on a previously developed formulation th

## Abstract This study examines the efficacy of using seismic isolation to favorably influence the seismic response of cableβstayed bridges subjected to nearβfield earthquake ground motions. In nearβfield earthquake ground motions, large amplitude spectral accelerations can occur at long periods wh
## Abstract The linear quadratic regulator (LQR) control algorithm is at the heart of many modern control design methods. There have been numerous publications dealing with LQR control and earthquake engineering. However, very few papers discuss the hysteretic loops produced by the LQR control forc
This paper considers the active vibration control of cables and cable/structure systems with an active tendon controlling the axial displacement of the cable anchor point. It is demonstrated that a force feedback based on a collocated force sensor measuring the tension in the cable is feasible and t
Ambient and forced vibration tests were carried out on the Beauharnois bridge, a unique, 177-m combined suspension and cable-stayed structure near Montreal, Canada. A rehabilitation program was completed on the bridge during which the deck was completely rebuilt with an orthotropic slab on two steel
