The method is based on simple equilibrium models representing thecombination of compression or tension stress fields mobilized at the ultimate condition. Thepaper presents tentative rules for the construction of the models with some specific proposalsfor walls subjected to different loading conditions. The performance of the proposed modelsis analyzed by comparison with numerical results generated by means of a well-known micromodelingtechnique for the analysis of masonry structures.37º <strong>IAHS</strong> <strong>World</strong> <strong>Congress</strong> On Housing Science 373
