Experiments performed on a ten-member fail-safe structural model subjected to variable amplitude, randomized, load sequences confirm predictions of fatigue life and reliability based on a probabilistic approach to linear damage accumulation and failure. The statistical variation in ultimate strength of 2024-T4 aluminum combined with an exponentially distributed Markovian, bending load sequence and with a constant amplitude S-N relation for single specimens is utilized in the analysis. Experimental results on the statistical distribution of bending strength, on constant amplitude flat bending fatigue tests with single specimens and with fail-safe structures, and on variable amplitude flat bending tests with fail-safe structures are reported.
