On the fatigue assessment of plain and short fibre/particle reinforced concretes

By reanalysing more than 1500 data taken from the literature, a unifying design curve is proposed
to estimate fatigue damage in un-notched plain and short-fibre/particle reinforced concretes subjected to cyclic
loading. The considered experimental results were generated by testing both plain and short-fibre/particle
reinforced concretes cyclically loaded either in tension, in tension/compression, in compression, or in bending.
From a design point of view, the most important feature characterising the proposed standardised methodology
is that the mean stress effect is directly accounted for through the maximum stress in the cycle under either
tension/compression or bending, and the absolute value of the minimum stress under compression (the above
design stresses being normalised through the corresponding static strength). The above strategy resulted in a
great simplification of the problem, allowing all the considered experimental results to fall within a narrow
scatter band.
