CE 541/ME 583 - Reliability of Engineering Systems

This course describes how to determine the probability individual components (e.g., beams, columns or connections) will fail and the probability that a system of these components (e.g., a structural frame) will fail. In a philosophical sense, it helps one realize that engineers can't guarantee a given outcome, rather we are providing reasonable odds that the outcome will be as desired. It also helps an engineer view things from a systems perspective, e.g., whether or not redundancy improves the reliability of the system -- it doesn't always -- and how reliable each component must be to improve the reliability of the system. These concepts form the basis of performance-based design.

All the current LRFD structural and geotechnical design codes are derived from reliability concepts. The course describes how these codes are derived.
