- Abstract
- Available literature concerning reliability considerations for fatigue analysis and design of structures is reviewed and summarized. Emphasis is on relatively simple methods with practical applications. Basic formulation of the structural reliability problem involving repeated load applications is described, and several probability distribution functions for fatigue lives with constant cyclic stress are discussed. Use of a linear cumulative damage theorem in structural fatigue is reviewed, and some random and/or full-scale fatigue tests are discussed. The work of Baldwin and others is reviewed in connection to relating test results of relatively small and simple specimens to the fatigue behavior of full-scale structures. Reliability aspects of nondestructive inspection and testing procedures are explored together with problem of damage assessment of existing structures. The report concludes that current knowedge is concerned primarily with behavior of relatively small and simple specimens subjected to a large number of repeated load applications.
