ANÁLISE COMPARATIVA DOS EFEITOS COM/SEM INTERAÇÃO SOLO ESTRUTURA COM FUNDAÇÃO PROFUN

Abstract

This objective of this work is to show through numerical comparisons the importance of considering the structure - soil interaction in the global analysis of the structures. The structural model used is a multifamily building, with reinforced concrete structure, on deep foundations. For the analysis considering the interaction of the soil-structure system is calculated with two soil profiles, one preponderant clay and the other sandy. The analysis methodology consists of an interactive process in which, initially, the superstructure reactions are determined, considering the indescribable supports, that is, without the soil-structure interaction and then, using the SISE'S module of the TQS program, it is calculated considering the bearings as stiffness springs. With this, we try to show that the integrated analysis of the structure and the soil allows a better estimation of the effects on the structural elements with the most real behavior of the interdependence of the efforts between the structure and the soil.
