In this paper, the influence of the mechanical properties of masonry in the structural behavior of old masonry dams in Mexico is evaluated. Mexico has an important number of masonry dams, which were constructed from seventeenth century to nineteenth century and continue to operate until now. Two different typologies of typical dams in Mexico were analyzed. The first typology corresponds to a dam with inclined faces (upstream and downstream) and the second one corresponds to a dam with a vertical face upstream and an inclined face downstream. The selected dams were analyzed by traditional methods, where the resultant of all forces acting on the dam must lie in the third middle of the base and the hypothesis of no tension material is assumed. Sometimes, this approach is too conservative and mostly does not reflect the real structural behavior of the dam. Thus, 2D models of both dams by means of a semi–discrete approach were performed. Considering the non-linear behavior a parametric study was made in order to identify the mechanical properties that have more influence on the structural behavior. Parametric analyses show that the tensile strength of the masonry is the property of greater influence on the structural behavior.
