The　bond　strength　considering　concrete　strength　and　non-uniformly　corrosion　was　tested　by　twelve　beam-type　specimens,　and　the　corrosion　was　characterized　by　the　3D　scanner.　According　to　the　K-S　test,　the　cross-sectional　area　of　the　corroded　bar　follows　the　lognormal　distribution　at　the　5%　significance　level,　where　its　mean　and　standard　deviation　linearly　correlate　with　the　mass　loss　rate.　The　probabilistic　bond　strength　is　pre-dicted　by　the　Monte-Carlo　method,　incorporating　the　uncertainties　of　the　cross-sectional　area　of　rebars　and　the　concrete　strength.　It　is　indicated　that　the　failure　probability　can　be　decreased　by　decreasing　mass　loss　rate　and　increasing　concrete　strength.
