Cílem tohoto příspěvku je ukázat spručněvýsledky asi dvacetiletého výzkumu životnosti betonových konstrukcí, zejména modelování, která byla konána na ústavech Stavební mechaniky a Chemie stavební fakulty VUT v Brně. Byly aplikovány statistické a citlivostní metody spolu s hodnocením úrovně spolehlivosti (pravděpodobnost poruchy). Bylo vytvořeno několik softwarových nástrojů, stěžejní je FReET-D, který zahrnuje v současnosti 32 modelů pro různé druhy degradace betonu či výztuže. Je ukázána aplikace na prognózu karbonatace betonové chladící věže včetně porovnání několika modelů s in-situ měřením.
