RESIDUAL FATIGUE-STRENGTH AND STIFFNESS OF ORDINARY CONCRETE UNDER BENDING

On the basis of the fatigue equation that had been previously proposed by the authors, a new formula for predicting the residual fatigue str ength of ordinary concrete was deduced. This formula was further verif ied and modified by the flexural tests on the concrete beam specimens and compared with other previous test data. Also, some residual fatigu e stiffness properties of concrete such as Young's modulus, Poisson's ratio and shear modulus were investigated using non-destructive testin g techniques. There was a good correlation between the stiffness prope rties and the residual fatigue strength. Copyright (C) 1997 Elsevier S cience Ltd.
