Abstract: 
Tension stiffening is still a matter of discussion into the scientific community. The study of this phenomenon is also relevant in structural members where the total reinforcement consists of a proper combination of traditional rebars and fibres. This paper aims at investigating tension stiffening by discussing pure-tension tests on reinforced concrete prisms having different sizes, reinforcement ratios and amount of fibres. The influence of fibres in determining a more distributed crack patterns characterized by narrower and more closely cracks will be discussed. It is worth noticing that the expected smaller crack widths in addition to a low concrete porosity (which strictly depends on the water/cement ratio) is of paramount importance for enhancing structural durability.
