FATIGUE LIFE OF PLAIN CONCRETE UNDER STRESS REVERSAL. FRACTURE OF CONCRETE AND ROCK: RECENT DEVELOPMENTS. PAPERS PRESENTED AT THE INTERNATIONAL CONFERENCE, UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, SEPTEMBER 20-22, 1989
In this paper, the effect of stress reversal on the fatigue life of plain concrete is studied through flexural fatigue tests on plain concrete beams. In the light of new experimental data, the fatigue equation containing loading frequency effects previously proposed by the first author is discussed, and a new fatigue equation including stress reversal effects is proposed. The conclusions from the work are that (1) the stress ratio significantly effects the fatigue properties of concrete; (2) stress reversal causes the fatigue life of concrete to decrease, and this effect can be expressed in the fatigue equation; and (3) a new fatigue equation containing the effect of stress reversal on the fatigue properties of concrete is proposed. It agrees well with test results of other researchers, and is suitable for many loading states other than bending. For the covering abstract of the conference see IRRD 829348.
