Abstract: Reuse of recycled steel fibres recovered from tire recycling is a sustainable solution to contribute to the reduction of the waste disposal burden. In addition, commercially availablesteel fibres are widely used in the construction industry, especially mixed with concrete to enhance flexural strength, toughness, ductility and cracking resistance. Various researchers have found that there is an opportunity to replace commercially available steel fibres with recycled steel fibres from tire waste. However, there are few studies on the behavior of reinforced concrete beams with recycled fibres. Therefore, laboratory experiments have been carried out to study the behavior of reinforced concrete beams cast with recycled fibres and commercially available fibres, which comprise a fibre content of 0%, 0.5% and 1% by volume. The results indicate that the load versus the displacement behavior of the reinforced concrete beams with recycled fibres is similar to that for commercial fibres. Moreover, a numerical analysis was performed, using finite element tool, ATENA, to study the behavior
of recycled fibre reinforced concrete, and to compare the performance with commercial steel fibre reinforced concrete. ATENA simulates real structural behavior, such as cracking, crushing and reinforcement yielding, by using non-linear finite element analysis. Moreover, the load-displacement diagrams computed in ATENA were compared to the experimental load-displacement diagrams.
