Fatigue Limit of Axially Compressed Concrete

Abstract

An attempt to evaluate analytically the fatigue limit of axially loaded concrete depending upon the load parameters, number of load cycles and static short-term strength is presented. The conventional limit of concrete microcracking statical sustained strength of concrete, curvelinear relationship between fatigue limit and load asymmetry coefficient and straight-line relationship between logarithm of number f load cycles and fatigue limit are involved into a consideration. The proposed method is applicable for the range of load cycles number from 10,000 to an indefinite large.
