Abstract: An analysis which combines heat and mass transport with the calculation of thermal stresses due to non-uniform temperature distribution is presented for a concrete wall exposed to different fire scenarios. The mathematical formulation of simultaneous heat an mass transfer is based on the averaging procedure over a representative elementary volume of the porous medium, and in the thermal stresses calculation, linear elastic strains are assumed. The results indicate that thermal stresses higher than those resulting from vapour trapped within the material may develop in concrete walls exposed to fire elevated temperatures.
