Testing of reinforced high performance fibre concrete members in tension

Ultra-high performance fibre reinforced concrete (UHPFC) is a high performance construction material, coupling strength, ductility and compacity. Up to the present time, its mechanical properties have been widely studied, but design approaches and structural applications in which it can be efficiently applied are needed. To improve this knowledge, a study on the behaviour of real-scale UHPFC ties with additional ordinary steel bars constitues an important step. The results of a test series presented here indicate that ordinarily reinforced UHPFC members in tension provide an optimal behaviour at the serviceability limit state. At the ultimate limit state, even a large amount of additional ordinary reinforcement cannot avoid a strain localisation and a brittle failure.
