“…Based on observation results obtained by Kato and Uomoto (2005), the author assumed corrosion is initiated when the chloride concentration on the surface of reinforced steel reaches a critical value, which is a uniformly distributed random variable in the range of 1.0-1.2 kg/m 3 . This work accounted for uncertainties in deterioration analysis that are related to the apparent diffusion coefficient, concrete cover and surface chloride concentration caused by environmental or construction conditions (Table 2) (AIJ, 2004;Kato & Uomoto, 2005;Takahashi, Sakai, Seki, & Matsushima, 2005). If the surveyed data exist, they can be used to conclude the statistics of deterioration parameters instead of Table 2.…”

“…This stage is followed by the deterioration stage, during which deterioration progresses and the structural capacity of members is degraded significantly. Based on a previously developed deterioration model (JCI, 2004), the author assumed the rate of corrosion in these two stages is identical, and this rate (expressed as percentage weight loss per year) is treated as a lognormal random variable with a mean value of V corr , which can be derived using Equation (18), and a coefficient of variation of 0.5 (Kato & Uomoto, 2005;Takahashi et al, 2005) (Table 2).…”

“…In the deterioration stage, the deterioration process progresses and the structural capacity of the members is degraded significantly. Based on a previously developed model (JCI 2004), the rate of corrosion in these three stages is assumed to be identical, and this rate (expressed in terms of percentage weight loss) is treated as a lognormal random variable with a mean, V corr , which can be estimated using Equation 3, and a coefficient of variation of 50% (Takahashi et al 2005):…”

“…In the probabilistic analysis, the carbonation coefficient and concrete cover are treated as lognormal random variables with coefficients of variation of 45% (Kawanishi et al 2006) and 20% (Kato et al 2005), respectively. sion in these two stages is assumed to be the same, and this rate is treated as a lognormal random variable with a mean equal to 0.06%/year (percentage weight loss) (Tottori et al 2004) and a coefficient of variation of 50% (Takahashi et al 2005).…”

“…(3) proposed in past research (Ozaki et al 2005). Based on previous research (Tottori et al 2004) and (Takahashi et al 2005), the rate of corrosion at this stage is equal to the rate of corrosion of steel without any concrete cover and is treated as a lognormal random variable with a mean equal to 0.14%/year (percentage weight loss) and coefficient of variation of 50%.…”
