Indicators for inspection and maintenance planning of concrete structures

摘要

Based on an idea introduced by Benjamin and Cornell(1970. Probability, statistics and decision for civil engineers. New York: McGaw Hill)and previous works by the authors it is demonstrated how condition indicators may be formulated for the general purpose of quality control and for assessment and inspection planning in particular. The formulation facilitates quality control based on sampling of indirect informa- tion about the condition of the considered components. This allows for a Bayesian formulation of the indicators whereby the experience and expertise of the inspection personnel may be fully utilized and con- sistently updated as frequentistic information is collected.
