Probability‐Based Design Criteria for Nuclear Plant Structures

This paper summarizes the results of a research program conducted during 1980–1985 to develop probability‐based analysis and design procedures for structures in nuclear plants. Limit states of concrete containments and shear walls are formulated. Probabilistic models for static and dynamic loads and structural resistance variables are established. Reliability analysis methods are established for estimating limit state probabilities for nuclear plant structures subjected to combinations of static and dynamic loads. Practical probability‐based design criteria are developed for concrete containments and shear walls in a load and resistance factor design format. The load and resistance factors are illustrated for several limit states and target limit state probabilities.
