Abstract EN
This paper investigates numerically the active tendon control of a cable-stayed bridge in a construction phase.
A linear Finite Element model of small scale mock-up of the bridge is first presented.
Active damping is added to the structure by using pairs of collocated force actuator-displacement sensors located on each active cable and decentralized first order positive position feedback (PPF) or direct velocity feedback (DVF).
A comparison between these two compensators showed that each one has good performance for some modes and performs inadequately with the other modes.
A decentralized parallel PPF-DVF is proposed to get the better of the two compensators.
The proposed strategy is then compared to the one using decentralized integral force feedback (IFF) and showed better performance.
The Finite Element model of the bridge is coupled with a nonlinear cable taking into account sag effect, general support movements, and quadratic and cubic nonlinear couplings between in-plane and out-of-plane motions.
Finally, the proposed strategy is used to control both deck and cable vibrations induced by parametric excitation.
Both cable and deck vibrations are attractively damped.
