EnglishMarble façade panels tend to exhibit bowing deflections even after a short time of exposure to environmental actions. In particular, under cyclic thermal action irreversible deformations accumulate due to a progressive decohesion of the calcite grains. In the present paper, a theoretical model, combining continuous mechanics principle and fracture mechanics tools, is presented to calculate the maximum bowing of the slab and its fatigue life under a given temperature time history. The model is applied to the case study of the court building of Pescara (Italy) to estimate the bowing deflection in the marble slabs due to thermal actions.
