Implementation of an Active Damping System to Reduce Harmonic Vibrations in a 3...

Moutinho, C.; Cunha, A.; Caetano, E.

This paper describes the work for a real implementation of an active damping system to reduce harmonic vibrations in a plane frame physical model with 3 degrees-of-freedom. For this purpose, it is suggested the use of an active mass damper commanded by a derivate controller which has the effect of increasing the modal damping coefficients in correspondence with a specific gain value. This control gain, as well ...


Vandal Loads and Induced Vibrations on a Footbridge

Caetano, E.; Cunha, A.; Moutinho, C.

The paper describes a study to characterise intentional human dynamic loads (vandal loads) and induced effects on a footbridge. The study comprehends the development of a numerical model to characterise the dynamic behaviour of the footbridge, which is experimentally validated and used to numerically simulate the response induced by groups of pedestrians synchronised at critical bridge frequencies. The vandal l...
