Fatigue Reliability: Development of Criteria for Design

Committee on Fatigue and Fracture Reliability of the Committee on Structural Safety and Reliability of the Structural Division, ASCE

Document Type: Journal Paper


This is the fourth in a series of four articles prepared by the ASCE Committee on Fatigue and Fracture Reliability. This paper summarizes how criteria for assuring integrity against fatigue and fracture may be developed using principles of engineering reliability analysis as a basis. The probabilistic treatment allows specification-writing groups to consider explicitly uncertainties that affect fatigue performance and fracture susceptibility when setting practical criteria for design. However, this treatment need not lead to more complex provisions at the design level. Several illustrations of these concepts are given.
