Paper Abstract
The objective of this study is to develop a numerical model of a stay cable interacted with deck, and to examine the
vibration suppression technique of the stayed cable subject to external loading. First, a numerical model based on the
finite difference method and the finite element method has been developed to simulate the effects of the bending
stiffness and its sag-extensibility characteristics of the cable. Accurate vibration mode shapes and modal frequency of
the interaction between stay cable and deck are examined. For the vibration control of cable, a MR-damper is used as
control device. This damper can be achieved either through the passive control strategy or the semi-active control
strategy employing decentralized sliding mode control (DSMC) and maximum energy dissipation (MED) on the staycable.
To verify this study, a scaled-down cable structure is designed and constructed in NCREE, Taiwan. A small
shaker is designed and mounted onto the cable to generate the sinusoid excitation with different amplitudes and
frequencies. Dynamic characteristics of the cable-deck system are identified and the system model is developed for
control purpose. The DSMC algorithm using MR damper was studied to reduce the cable vibration under different
excitation frequencies.
