CORRELATION EFFECTS ON RELIABILITY ASSESSMENT OF STRUCTURAL SYSTEMS
Abstract eng: Reliability of a structural system is assessed for both noncorrelated and correlated structural components. The existence of correlations among components of structural systems is examined in this paper. Simulation methods are used to model correlations among structural components and to assess the components and system probabilities of failure. Fault tree analysis is used as a method for assessing the reliability of systems. A variance reduction technique is also used to improve the simulation efficiency and accuracy. The results showed that correlation among structural components affected the reliability of structural systems. Correlations also affected the sequence of combined failures of components in the system. The use of variance reduction technique improved the simulation efficiency and accuracy.
