Abstract

Based on previous work by the authors a Bayesian formulation of condition indicators is developed further whereby in conjunction with a systems modelling of concrete structures the experience and expertise of the inspection personnel may be fully utilized. It is shown how the predicted evolution of the deterioration of the structure may be consistently updated based on inspection results. This facilitates that inspection results may be used in the long term planning of inspection and maintenance of structures. The approach is illustrated on an example considering half-cell measurement inspections of a concrete structure subject to corrosion due to ingress of chlorides
