Abstract:The work described in this paper is part of a research investigation into the fatigue life of prestressed concrete flexural members where crushing of the concrete compression block precedes the fracture of the tension steel reinforcement. The results of constant load cycle tests conducted on plain concrete specimens to study the effect of compressive stress gradient on fatigue life are presented and discussed. Application of the results of the study for estimating beam fatigue life as limited by fatigue failure of the concrete in compression is briefly discussed. An approximate design I check against the possibility of concrete failure in beams subjected to repeated flexural loads is formulated for a specified fatigue life N = 2,000,OOO cycles and probability "design limit" P < 0.00001.
