Modelling the dynamic force of bridge crossings

Abstract

Viscoelastic elements of Kelvin-Feugt type are supposed to be used for modelling dynamic influences from the transport side and dynamic behaviour of separate elements and the whole structure as a whole. Periodic monitoring of bridge crossings using the considered approaches will make it possible to detect the presence of defects in the span itself, associated with the formation of cracks, spalling, because in the presence of such defects the estimated frequencies change.
