This article considers calculation method of structural strength coefficient, that ensures the requiredserviceability. The special emphasis is placed on limiting stress evaluation when structures are subject to multi-cycleasymmetric loading. The suggested approach enables to evaluate proof strength more correctly within the designprocess.References
