Active control of civil structures: Theoretical and experimental study
Cable-supported structures and particularly long-span suspension or cable-stayed bridges are among the most important engineering structures of the second half of this century. Improvements in materials led to the construction of progressively longer, structurally more efficient and slender bridges. But consequently, structures are more and more flexible and more sensitive to wind as well as to "live-load" induced vibrations. This justifies the development of appropriate active damping devices. After a brief presentation of the strategy for damping cable structures with active tendons, this paper gives an overview of large-scale experiments performed in the frame of the Brite-Euram project ACE. Finally, the paper reports on the outputs of the outgoing EC funded project CaSCo dedicated to semi-active control of civil structures.
