Flexural Fatigue Strength of Plain Concrete
ACI Materials Journal, 1993 This paper presents a new expression to describe the flexural fatigue strength of plain concrete. It incorporates the effects of stress ratio and stress level into the faitgue equation and allows a statistical description of fatigue life in terms of both stress level and stress ratio. A concept of equivalent fatigue life is introduced in the derivation
