Structural and economical performance of reinforced concrete frames with Dual?Phase and TempCore® steel rebars in uncorroded and corroded conditions

In the last decades, need to develop new enhanced typologies of steel reinforcement bars with improved ductility and durability performance in presence aggressive environmental conditions progressively increased due negative consequences that corrosion showed on structural capacity reinforced concrete (RC) buildings. Within recently concluded NEWREBAR research project, a reinforcing grade Dual-Phase (DP) microstructure selected low-carbon content chemical composition (kept range actual European production) was developed, produced, tested even accelerated induced corrosion. To understand impact adoption DP rebars RC structures, case study buildings were designed, modeled, analyzed using compared traditional TempCore® rebars. present work, results techno-economic analysis performed both through evaluation expected annual loss (EAL) index is presented for residential five-storeys case-study building, assessing benefit introduced by adopting proposed
