In this work will be analyzed the values obtained for the stresses in the base of the walls of masonry of the first pavement of a building in structural masonry and resting in strip foundation, considering the resulting effects of the interaction among the integral parts of the structural system and the soil in which it rests. It will be made a brief study on the several soil models for the evaluation of the soilstructureinteraction aiming to choose the most appropriate to simulate the behavior of a construction. After the choice of the model for the representation of the soil, it will be made the modeling and the analysis of the construction through a commercial program based on the finite elements method. So that can evaluate the influence of the soil-structure interaction in the distribution of stresses, the foundation soil will be represented by different models of calculation, varying of a model where the soil is considered plenty stiff until a soil little stiff. Also the influenceof loading process of the structure will be evaluated in the redistribution of stresses, being analyzed the results for the hypothesis of instantaneous loading, of two in two floors and of four in four floors.
