Paper Title:
Nonlinear Finite Element Analysis of Corroded Reinforced Concrete Lock-Walls
  Abstract

Reinforcement and concrete can work together to bear load in reinforced concrete structures, one of the main reasons is the relatively prefect bond between reinforcement and concrete. When steel reinforcement corrodes, the bond strength decreases and leads to the degradation of the reinforced concrete members. This paper built a finite element model by selecting appropriate stress-strain relationship of concrete and reinforcement, bond-slip relationship between concrete and corroded steel bars. The flexural behavior of corroded reinforced concrete lock-walls was analyzed by nonlinear finite element method. The calculated results were compared with the test results to verify the reliability of the finite element model. Finally, the influence of corrosion level of steel reinforcement and concrete strength on the normal section bearing capacity of lock-walls were discussed.
