Keywords: crest values, resource evaluation, work of external forces aiming at sample destruction, S-N curve, random loading

The study proposes a method for evaluating the endurance life of structure elements. The method is based on constancy of total work of external forces destructing the sample, and independency of this work on the crest value. We built the structure element durability line, which involves using all crest values of the effective spectrum when evaluating the work of external forces. We evaluated the resource, applying the method proposed and using the working structure.
