title = "Modelling inspection and fatigue retrofitting by post-weld treatment in bridge management systems",
abstract = "Bridge management systems (BMSs) are routinely used to model the deterioration of bridge components due to manifest processes, such as deck surface wear and corrosion. Fatigue deterioration and retrofitting are generally not modelled in BMSs, however, primarily due to the difficulties associated with detecting fatigue damage at its early stages. In this paper, a simple Markov chain fatigue model, similar to those commonly used in BMSs to model other deterioration processes, is described and evaluated by comparison with a previously validated probabilistic mechanistic (strain-based fracture mechanics) model. Several alternative fatigue management strategies employing various combinations of weld inspection (magnetic particle inspection) and retrofitting by post-weld treatment (needle peening) are analyzed. Based on the results of these analyses, conclusions are drawn regarding the suitability of the Markov chain model for making life-cycle cost comparisons of fatigue management strategies employing inspection and post-weld treatment.",
