Abstract
Numerous methodologies can be used in numerical analyses of masonry structures. In the engineering applications which allow current design standards linear elastic material models are used. On the other hand, when it comes to the analysis of morphology of cracking and the failure mechanism that form the basis of scientific studies, the choice of use falls on the advanced material models implemented in masonry micro-, macro- or mezo-models taking into account the fragile properties of masonry based on the Coulomb's ideas. The Drucker-Prager, Hofman, Willam-Warnke, Barcelona and the Menétrey-Willam (M-W-3) models are used, among others. All advanced material models require the introduction of many mechanical parameters, the determination of which may pose many problems. Many authors use their own test methods, so it is not possible to repeat calculations. The paper presents the author's method of validating numerical masonry models using standard research models and procedures. The elastic - brittle material model (SBeta) and the elastic - plastic model of Menétrey – Willam (M-W-3). The basic material parameters of masonry units and interface elements were determined in the tests of specimens of masonry units' elements or wall specimens. The validation was carried out in the ATENA FEM system using a 2D model of the wall axially and diagonally compressed. The cracking of the wall, values of elastic modulus and destructive stresses as well as the course of the load-displacement dependence were compared.
