The impulsive loading influence on dynamic response parameters of the viaduct type structure

Résumé

Bridges and viaducts are vital structures ensuring ways of communication, so they must be protected from dynamic loads from traffic or seismic activity. For this reason are embedded in their structure dynamic isolation systems for damping and isolating the shocks and vibration to which they are subjected. For a correct choice, from the dynamic point of view of viscoelastic type systems and to estimate their optimal lifetime is required thorough knowledge of the dynamic loads to which they are subjected. In this paper will be analyzed from the experimental point of view, the disturbing signals stemming a heavy vehicle from passing at different speeds over an obstacle positioned transversely to the travel position.
