BAYESIAN TECHNIQUE FOR EVALUATION OF MATERIAL STRENGTHS IN EXISTING BRIDGES

The 1990 version of Clause 12 'Existing Bridge Evaluation' of CAN/CSA-56 'Design of Highway Bridges' permits the evaluator to assess the material grade in an existing bridge using a simple Bayesian technique. Bayesian techniques are compatible with familiar decision-making strategies and are usefuul when decisions must be made on the basis of limited information. This paper presents background information for the evaluator who may be unfamiliar with Bayesian techiniques. The basic workings are explained through a simple example. Sources of error in Bayesian techniques are flagged and discussed.
