Active tendon control of suspension bridges: Study on the active cables configuration

In a previous study, thepotential of damping suspensionbridges with active stay cables has been evaluated on a numerical modelof a suspension bridge, and demonstrated experimentally on a laboratory mockup. In this paper, we extend our study to explore two different configurations of the active stay-cables: One classical configuration, corresponding to attaching the active stay-cables between the top of the pylons and the deck(configuration I) and, another configuration, consisting of attaching the stay-cables between the base of the pylonsand the catenary (configuration II). The analysis confirmed thatboth configurations are effective with a slight superiority of the second configuration. The study is conducted numerically and experimentally on a suspensionbridge mock-up, by considering two types of active stay-cables. The experimental results confirmed the numerical predictions, and demonstrated the effectiveness of the second configuration.SCOPUS: ar.j
