Study of the Deformation Capacity of Corroded Passive Rebars

The steel used as passive reinforcements in reinforced concrete structures must have certain resistance requirements and also meet minimum ductility condi-tions. The ductility requirements have increased significantly since the 1980s as a result of the increasing use of analysis procedures for reinf...
