Functions of the following dependence “upper level of cyclic load η cyc - number of cycles to failure n cyc ” are obtained. Hyperboli c curves of low-cycle fatigue of fine-grained and coarse-grained concrete are constructed. The limits of short-cycle fatigue of each type of concrete were determined. The analysis of the performance of each type of concrete under the action of low-cycle loads of high levels is carried out. © 2026 The Authors. Published by ELSEVIER B.V.
