| Abstract: | The concrete carbonation, steel bar corrosion and concrete cover cracking are the main factors deteriorating the reinforced concrete structure. Based on finite element simulation and experimental study of corroded reinforced concrete flexural members, an analysis approach and calculation models for flexural and shear strength of corroded reinforced concrete flexural member are proposed. The varying character and rule of flexural and shear strength for corroded reinforced concrete flexural member are given by an example, |
