Abstract

Highlights: [•] Models that relate mechanical properties with corrosion degree have been obtained. [•] The variation of yield stress and ultimate strength does not depend on the diameter. [•] Bar resistance reduction is lower than the one caused by section loss. [•] Deformation energy density undergoes higher decreases than yield stress or strength. [Copyright &y& Elsevier]

Abstract

The mechanical and structural behavior of three stainless steel (SS) reinforcing bars (austenitic AISI 304, duplex AISI 2304 and new lean duplex AISI 2001) have been studied and compared with the conventional carbon steel (CS) B500SD. The study was conducted at rebar level, cross-section level and structural member level. The results demonstrate higher ductility performance for hot-rolled SS rebars than for CS, but lower ductility for cold-rolled SS rebars compared to CS. The experimental elastic modulus of SS rebars is lower than that of CS. [ABSTRACT FROM AUTHOR]
