Análise da interação solo-estrutura em edifícios de concreto armado com fundações profundas

Abstract

This paper consists in analyzing and compare the variations in the efforts caused by structural elements, horizontal displacements and efforts in foundation of a building designed upon a nom-movable structures and other where is the consideration of interaction soil-structure. The foundations of both models are deep models of the type helix continues. Studies realized on a wide bibliographic review evolve the subject and the área, allowing the obtainment of parameters and variables in the project. The analyze of soil structure interaction (SSI) was developed by the structural analyzes software based in the method of finite elements (SAP2000v12). Between the used tools for data obtainment, was used the numerical examples the computational system SSIS (Soil Structure Interaction System) – developed by TQS informatics, of which discretized the foundation to be analyzed in each meter generating a modelo of “springs” that will be introduced in the software of finite elements SAP2000v12. The results described in this paper show that must be taken in consideration the effect of soil deformability, even in a simplified way, replacing the hypotheses of the edification upon non-movable supports in the structural projects. The consideration of interaction soil structure in the edification of multiplex floors reproduces a bigger realism in the construction of it.
