IL CONTROLLO STRUTTURALE DELLE VIBRAZIONI NELL'INGEGNERIA CIVILE

Structural control is becoming more and more important for civil structures, particularly for mitigating vibrations due to natural phenomena as well as due to human action. This note examines in its first part structural control strategies (active, semi-active, passive) applicable to civil structures, pointing out the differences with other fields of engineering, recalling the principles on which are based, the peculiarities and advantages. Particularly, semi-active strategies have been proved advantageous. For this reason, in its second part, the note presents a review of the principal families of devices with relation to their applicability in the field of control of civil structures and to their suitability of being used inside semi-active control schemes.
