Assessment of performance and optimal strategies for inspection and maintenance of concrete structures using reliability based expert systems

A new expert system has been developed which can assist the inspector during the inspection on the site of the bridge and will supply information on the causes of observed defects, appropriate diagnosis methods and related defects.
A second expert system has also been developed which is used as a decision tool for the inspection after the inspection is completed and after testing in the laboratories has taken place.
A number of FORTRAN modules, MISDAT, BETAEQ, RELIAB and INSPEC has been developed and implemented on basis of existing software. These modules are used in the expert systems, but can also be used independently (eg to estimate the reliability of any structure).
New stochastic models for corrosion, inspection, maintenance and repair are used in the expert systems, but are also of great interest in other connections.
New experimental results on corrosion, repair materials, strength of damaged structural elements and long time behaviour of concrete structural elements have been found.
