Application of recycled steel fibres in concrete elements subjected to fatigue loading

Properties of concrete elements under fatigue load can be enhanced by adding steel fibres to the concrete mixture. An experimental study of recycled steel fibre reinforced concrete elements subjected to cyclic load is described. Fatigue design models are presented according to the fib Model Code 2010, ACI 215, and JSCE guidance. Design model calculations are compared to the results of experimental analyses. It can be observed that, as a rule, all design models underestimate the experimentally obtained fatigue resistance of concrete elements. The adjustment of the fib Model Code design model is proposed.
