Abstract

Most bridges in western countries were built according to old codes that foresaw design loads inconsistent with today's traffic demands, so transportation agencies often do not know how to respond to transit applications on their bridges. In this contribution we illustrate how this problem is addressed by the DoT of the Italian Autonomous Province of Trento (APT). The approach of APT is not authorize movement of overweight loads unless it is demonstrated that their effect is less than that of the nominal design load. When this condition is not satisfied, a formal evaluation is carried out in an attempt to assess a higher load rating for the bridge. If, after the reassessment, the rating is still insufficient, the bridge is classified as sub-standard and a formal evaluation of the operational risk is performed to provide the APT with an estimate of the risk of transit of the overweight vehicle.
