In this paper is reported more generally some recent research on the load induced thermal strain (LITS), that causes a significant relaxation and redistribution of thermal stresses of concrete beyond the uniaxial compression regime. More specifically, the deformations induced by virgin heating of concrete beams subjected to sustained bending are considered. All experiments were carried out as 3-point bending with plain concrete beams placed in a furnace up to 600°C with different heating rates and stress levels [I]. To achieve this goal, it was important to study in de
