ABSTRACT
The aim of this study is to model the damage mechanisms of concrete and to investigate the behavior of concrete specimens when they are simultaneously subjected to a constant compressive load and to high temperature. To show the structural effect of such loading, numerical simulations of the experimental tests carried out by Holst [1] have been performed.
