Characterization of Bearings Nonlinearities Influences on Viaducts Dynamic Responses

Abstract

In view of viaducts designing and safety exploitation it is necessary to evaluate both theoretically, and instrumentally the dynamic behaviour for impulsive external actions. In this study the dynamic response for a singular bridge section was analyzed. There were considered only two degrees of freedom and the impulsive perturbations derived from the serviceable instrumental tests performed for this kind of construction objective at its commissioning.
