Cracking behavior due to rebar corrosion for concrete specimen with single rebar was evaluated analytically. The evaluation was performed by comparing with results of the electric corrosion test. Three-dimensional RigidBody-Spring-Method (RBSM) with three phase material corrosion expansion model was applied to simulate internal cracking patterns and surface crack width propagation. The effect of rebar local corrosion and penetration of corrosion products into cracks during the corrosion process were investigated and cracking behavior due to rebar corrosion was evaluated quantitatively.
