Modelling of reinforcement corrosion in concrete
Original language description
Corrosion of reinforcing steel in concrete is one of the most influencing factors causing the degradation of reinforced concrete structures, conducting to concrete cracking and spalling. The detrimental effect of corrosion is due to the fact that a rustproduct has a volume 2 - 6 times larger than the original steel. Consequently, the rust products exert an expansive stress on the surrounding concrete whose tensile strength is usually low. This paper attempts at the application of an analytical and numerical approaches to simulation of concrete cracking due to corrosion of reinforcement. At first, a combination with detailed analysis of two analytical models proposed by Liu & Weyers (1998) and Li et al. (2006) is suggested and presented. Four distinctphases of the corrosion process are identified and a detailed guide through the mathematical development is described. In the next, numerical computations obtained with nonlinear finite element code are presented. The model features the s
