Abstract

The control of structural vibrations produced by earthquake or wind can be implemented by various methods such as modifying rigidities, damping, or shape, and by providing passive or active counter forces. To date, some methods of structural control based on the use of various active, semi-active, passive and hybrid control schemes have been used successfully and offer great promises. An overview of the experimental activities in structural control performed at the ELSA laboratory is presented. After a short presentation of passive techniques, we illustrate in more detail an innovative way to reduce the vibrations of cable-stayed structures by the application of an active damping strategy. Finally the concept of semi-active control is presented.
