Both basic components, i.e. the stone blocks and mortar joints, are viewed as quasi-brittle materials with inherent strain softening response, which (in dependence on fracture toughness of both components) manifests itself by the localization of inelastic strains mainly into the mortar beds between stones. With reference to their topology it appears useful, at least for computational purposes, to treat these material systems in the framework of multi-scale modeling based on homogenization techniques for the determination of material parameters on the mesoscopic level. The PUC serves as a suitable tool to determine the effective thermo-mechanical properties of the masonry and macroscopic loading paths that become the input data for the modeling on macroscopic level. The first part of this contribution is focused on determination of the fracture energy and the second part deals with evaluation of the effective heat conductivity with consideration of jumps between stone blocks and mortar.
