Abstract: Knowledge representation and reasoning, considered of a major importance for building and practical application of the structural reliabilty assessment expert systems, are the issues tackled in the research described in the paper. The concept developed in the research allows successful introduction and use of standard and/or heuristic engineering knowledge (procedures, code calculations, etc.), of preceding operational experience, of testing results and experimental evidence, etc., into expert systems. The concept has been applied in the prototype expert system for the leak-before-break analysis, where the results of the over 50 large scale MPA-tests have been taken as a basis for knowledge elicitation and verification of the system.
