It has been oriented towards the search of simple methods that allow in practical  way, to estimate the maximum load that can be supported by masonry walls subjected to the  combined action of compressive vertical and horizontal shear loads.     the first phase of this research was dedicated to the collection and analysis of the state of the  art related to the study of the mechanical-resistant behavior of masonry walls, in either  experimental or analytical level. This literature review was continued throughout the whole  process of the research. In subsequent stages, results of selected experimental campaigns on  masonry walls were used to calibrate and\/or validate the performed numerical studies.     subsequently, a numeric micro-model was selected to be used as a tool to verify and\/or adjust  the initial proposals of simple models. These simple models are based on the struts and ties  method which uses the struts to represent the compressive stress fields and the ties for tension  zones, both of them forming a resistant mechanism. The objective was to predict satisfactorily,  by means of the numeric micro-model, the ultimate loads and mechanisms of fracture observed  in the experimental campaigns on masonry walls reported in the literature.     the available data from experimental campaigns, helped to validate the numerical micro- models that were used in the two cases of vertical load studied, uniform and partial or  concentrated loads. Then a parametric study was conducted in order to determine the influence  of several variables and geometrical properties on the structural behavior of masonry walls. The  results of this study allowed us to evaluate  the ability of simple models to represent the  influence of the analyzed factors on the response of the wall.     in the case of uniform vertical load was evident, in general, that simple models presented a  satisfactory performance in predicting the ultimate response of the evaluated walls. The case of  partial or concentrated vertical load required  the modification of the original simple models  proposals in order to include other factors that  influence the response of the wall according to  the numerical results. This modification was done  by contrasting different stress distributions  stresses obtained numerically with the proposed resistant mechanism of the simple models.     the final result of this research consists on the proposal of a simplified method for the analysis  of simple walls in masonry under biaxial states  (compressive and shear) of solicitations on its  plane.     finally, the conclusions drawn from the current research are summarized and recommendations  for future works are given.<\/p>\n<p>&nbsp;<\/p>\n<h3>Datos acad\u00e9micos de la tesis doctoral \u00ab<strong>Modelos
