| Research Abstract |
In this study, at first, deterioration prediction method based on statistical simulation for flexural load bearing capacity of RC members under chloride attack was developed. Secondly, non-destructive evaluation method for mechanical performance for RC members with corroded rebars was improved. Finally, sequential update methods by using both deterioration prediction method and non-destructive evaluation method were developed. As a result, it was revealed that these methods developed in this study could evaluate mechanical performance and estimate deterioration of RC members exposed to marine environment quantitatively with high accuracy.
