Steel corrosion is the main occasion for durability degradation of concrete structures. For existing corrosion-expansion models of reinforcement, effects of stirrups were not considered, thus, they cannot entirely reflect the actual corrosion and expansion states. Based on uniform corrosion hypothesis and current models, a corrosion-expansion model for steel in concrete members is presented, which considered the effects of stirrups. Verification result of the model by test data indicates its full significance in structural inspection and life evaluation fields.
