In lifetime estimation, the FEM analysis method is proposed for predicting corrosion
failure time of concrete structures exposed to sea-water. This study shows that the
corrosion rate of rebar in artificial pore solution can be transferred to the corrosion
rate of rebar in concrete using the relationship between pore volume and concrete volume
by Jennings model. And this study considered the pitting corrosion effects of
reinforcement bar on corrosion failure analysis, rebar size to cover depth and
nonlinear crack analysis. These analysis results have good accordance with the
experimental results of Williamsons work. This methodology can be applied to lifetime
prediction procedure ofreinforced concrete structures and also gives more reasonable
results of concrete cover failure time estimation of reinforced concrete structures
exposed to sea-water.
