This paper presents a reliable method for assessing structural performance of reinforced concrete structures. A spring network model, which is one of the discrete-type numerical approaches, is used to predict current structural performance of deteriorated reinforced concrete structures due to steel corrosions. The influence of corrosion distribution of steel reinforcing bars on flexural behavior of reinforced concrete beams is studied. The numerical results indicates that the flexural capacity of reinforced concrete beams with steel corrosion depends on the minimum cross sectional area of corroded steel bars, and ductility of beams is strongly influenced by the condition of bond deterioration between concrete and steel bars. |
