L’INFLUENCE DE LA NON REGULARITE DES CHAUSSEES SUR L’AMPLIFICATION DYNAMIQUE ET LA DEGRADATION D’UN TABLIER D’UN PONT EN BETON ARME

Abstract

During the evaluation of a deck slab , the application of inappropriate dynamic amplification factors could have significant implication . The dynamic Response of a deck slab only depended on many factors. • With an increase in roughness leading to an increase in dynamic amplification factors. • An overloaded truck produces a lower dynamic amplification factor in a deck slab than an empty truck. • The truck speed influences the dynamic interaction. In this paper, we present model for the bridge and the vehicle as well to stimulate the dynamic response of the bridge.
