| Abstract: | This paper carries out accelerated corrosion tests for reinforcing steels embedded in concrete by electrochemical method.Reinforced concrete members with bending and compression loads are experimented and analyzed for its seismic characteristics.Through experiments,the influences of reinforcement corrosion on the initial stiffness,ductility,descent of bearing capacity and energy dissipation of the members are discussed.The influences of reinforcement corrosion on the shear capacity are analyzed theoretically,and calculating formula for the shear strength is proposed.Calculating results by the proposed formulas have good agreement with the experiment results. |
