Effects of loading frequency and stress reversal on fatigue life of plain concrete

Abstract

The effects of loading frequency and stress reversal on the fatigue properties of concrete were investigated by conducting flexural fatigue tests on plain concrete beams. A new fatigue equation based on the classical Aas-Jakobsen S—N equation is proposed which contains the above effects. This equation agrees well with previous experimental results and proves to be suitable for some other loading states other than bending.
