In order to investigate the expansive behaviour and cracking due to corrosion of reinforcement, the joint element which represents a corroded part was formulated, and the elasto-plastic finite element method with its element which was expanded by introducing the volumetric strain was carried out on a section of RC beams damaged by corrosion.
The analytical results show that the relation between weight-losses of steel bar and coefficients of expansion for cracking is obtained, and that the pressure value and the coefficient of expansion for cracking on a concrete surface is about 100kgf/cm2 and 2.0-2.2 respectively.
