Analytical dependencies for its determination are established. The method of experimental studies of steel fibre-reinforced concrete prisms under low-cycle compression is presented. Experimental studies of steel fibre reinforced concrete fatigue under low-cycle compression have been carried out. It is established that the relative low-cycle compression fatigue for steel fibre-reinforced concrete can be taken at 0.75. © 2024 The Authors. Published by ELSEVIER B.V.

Introduction Modern buildings and structures are constructed from a variety of materials (Kroviakov et al. (2020); Sobczak Piastka et al. (2020); Yasniy et al. (2022); Homon et al. (2023)). During operation, materials, elements and structures of buildings and structures must be durable and reliable and meet the requirements of regulatory documents (Kos et VII International Conference “In -service Damage of Materials: Diagnostics and Prediction ” (DMDP 2023) Experimental and theoretical studies of fatigue of steel fibre reinforced concrete under low-cycle compression Serhii Drobyshynets a , Yevgenij Babych b , Pavlo Sunak a , Iryna Zadorozhnikova a , Inna Parfentyeva a , Volodymyr Pakharenko b , Sviatoslav Homon b* a Lutsk National Technical University, Lvivska 75, 43018 Lutsk, Ukraine b National University of Water and Environmental Engineering, Soborna 11, 33000 Rivne, Ukraine
