Abstract
A reliability and maintainability analysis of structural system based on the Monte Carlo simulation technique is presented. Cyclic load acts on the structural system which is constructed by some sub-systems. Pre-existing cracks in a sub-system grow up under cyclic loading, and failure of sub-system occurs when the length of crack reaches the critical length. The structural system is subjected to periodic non-destructive inspection. If a crack is detected during the inspection, repair or replacement of the relevant member renews the structural strength. Some models for the analysis are given and analyzed, and also effectiveness of peiodic inspection is numerically recognized.
