Book excerpt: NEWREBAR research project aims to develop a new typology of steel reinforcing bars provided by enhanced properties in terms of ductility and durability towards aggressive environmental conditions. The need of such kind of steels depends by the fact that the decrease of ductility both under monotonic and cyclic loading conditions was assessed for most of actual reinforcing steels (e.g. TempCore ) exposed to corrosion phenomena. During the project, two final reinforcing steel products were developed and industrially produced, called respectively DPF and DPD in relation to the specific chemical composition selected for their realization, almost aligned with what actually on market and therefore not related to production costs' increase. Results of experimental tests and correlations highlighted the improvement in terms of durability performance of Dual-Phase steel reinforcing grades concerning ductility (Agt mainly) respect to traditional TempCore grades, with higher residual values of deformation capacity and, therefore, benefit to the overall structural performance. With the aim of fully understanding the influence of Dual-Phase steel bars to RC constructions, several case study buildings were designed according the capacity design approach: numerical nonlinear models were elaborated to assess the buildings' behaviour through pushover or incremental dynamic analyses in which the nonlinear behaviour of elements was modelled using a lumped plasticity approach, where the moment/ rotation behaviour of hinges was calibrated basing on the results of experimental tests performed on full-scale prototypes. Basing on the results of both mechanical characterization of DP grades and numerical analyses' results, recommendations for the adoption of DP grades in RC constructions were elaborated, as well as indications for introduction in current European standards.
