An engineering assessment of probabilistic structural reliability analyses

Abstract The application of probabilistic structural reliability analyses to complex structural components and/or systems involves a multitude of engineering problems or decisions, many of which are outside the experience of conventional engineering analysts. The purpose of this paper is to provide some practical perspective on such applications so that the methodology can be more effectively utilized as input to design decisions. Specifically, the discussion covers the most important considerations in applying structural reliability methodology, the limitations and implied development needs of structural reliability analysis state of the art, and some practical guidance on the level of detail in applying the methods to engineering problems. Specific examples are presented.
