| Abstract: | Based on a large number of test data of corroded reinforced concrete beam, flexural stiffness degradation coefficient about different corrosion methods and corrosion rate are obtained and a theoretical calculation formula of beam flexural stiffness degradation coefficient and rebar corrosion rate is fit. Then the reliability and accuracy of the formula are verified through the new reinforced concrete test beam of accelerated corrosion test. |
