MORENO HERRERA, Joel Alberto; VARELA-RIVERA, Jorge; VISAIRO MENDEZ, Rebeca  e  CASTRO-BORGES, Pedro. Flexural behavior of reinforced concrete beams with electrochemical parameters associated with high level of corrosion. Rev. ALCONPAT [online]. 2022, vol.12, n.3, pp.422-432.  Epub 08-Abr-2024.

In this work the change in the flexural behavior of reinforced concrete beams was evaluated. Beams without corrosion and beams with electrochemical parameters associated with high level of corrosion were considered. The electrochemical parameters considered were the corrosion rate, the electrical resistivity, and the concentration of chlorides. Beams were subjected to vertical incremental loads until failure. Cracking pattern, yielding load, maximum load, yielding stiffness, and displacement ductility of beams are presented. Based on the analysis of these structural parameters it is concluded that the flexural behavior of beams with and without corrosion was similar.

Palavras-chave : reinforced concrete beams; corrosion; sustained loads; structural behavior; electrochemical behavior.
