Bridge Analysis and Evaluation of Effects Under Overload Vehicles (Phase 2)

The use of special purpose highway vehicles, over the legal limit in size and in weight, is increasing as industry grows and large items must be shipped over highways. Overload vehicle crossing of a bridge, even if it is a single crossing, may affect not only the short term behavior of the bridge but also the long term performance and life cycle cost of the bridge. There may be minor cracking or deterioration in the components of the bridge which are not critical in the short term period but can result in special maintenance, rehabilitation or reduced life span in the long term. It may be reasonable for the permit applicant to be responsible for the reduced life of the bridge. The work completed in this project aims to help agencies in evaluating the long term impact of the vehicles on bridges and in assigning the resulting cost to the permit applicants as an extension of the first phase of the project. Long term behavior of concrete decks and steel girder bridges was investigated and a means to assign cost to the overloads was developed. Miner’s damage accumulation rule and life cycle cost analysis of bridges were used to develop the means. Examples of assigning cost per crossing bridges with overloads is provided for practical application of the developed means. The first set of examples were performed for two pilot concrete decks and the second set of examples were performed for two pilot steel girder bridges.
