Abstract	This paper presents a program for consideration of the soil-structure interaction in the spatial analysis of frame structures. The method is based on the assumption of Winkler, which allows discrete adjacent springs to the shallow foundations simulating the influence of the settlements of support in three-dimensional structures. Although the model is in 3D and thus all the six degrees of freedom of each support may suffer displacements due to a settlement, in this paper, the analysis was made considering only the influence of the vertical translation of the support. The work consists in adding the methodology for consideration of flexible supports to the flowcharts presented by Gere and Weaver, Jr. [1], using the stiffness method, which is widely used for the frame structures analysis. Through the integrated analysis, contemplating parameters of infrastructure, superstructure and foundation ground, it was proved that the deformability of the soil has significant influence on the efforts redistribution and the entailment between the soil and the structure that best describes the physical behavior of a building and flexible supports condition.
