Evaluation of Bridge Safety and Remaining Lifeby Fred Moses, Case Western Reserve Univ, United States,
Abstract: In developed countries, the emphasis on the infrastructure is changing from new construction to the safe maintenance of existing structures. Highway bridges represent an excellent example where a proper balance between safety and economy is necessary to make rational decisions concerning allocation of costs for inspection, repair, maintenance, rehabilitation and eventually replacement. The paper describes two recent projects to implement reliability methods in codes for evaluating safe strength of existing bridges and also assessing the remaining safe life (fatigue).
