Abstract: Models of structural reliability are called upon to provide not only initial estimates of safety, but also revised estimates reflecting new information on the structure as it becomes available. The types of performance information vary widely in quantity and quality, including age, the results of load testing, nondestructive measurements, information on past loads and service environments, and even subjective assessments of the state of damage or serviceability of the structure. In this paper an overview is taken of reliability re-assessment and model revision, and the example of load testing is used to illustrate design-point estimates of revised reliability.
