ABSTRACT
A finite element stress analysis model is presented that has been developed for numerical prediction of stress states in a reinforced concrete structural element exposed to rapid heating. Using a computational methodology presented to analyze stress states associated with coupled hydro-thermal behavior of concrete exposed to severe fire conditions, multidimensional finite element models that characterize structural response of reinforced concrete columns exposed to radiant heating conditions are developed. Effects of steel reinforcements on coupled heat and moisture transport phenomena are also considered.
