Abstract in Portuguese
Neste trabalho estuda-se a interação solo-estrutura de grupo de edifícios com fundações superficiais, em maciço de solos de argila mole. O comportamento ao longo do tempo da argila mole é analisado com o modelo reológico de Kelvin. Os parâmetros do modelo são determinados através do ajuste entre as curvas recalque – tempo do modelo e as curvas medidas em três prédios, construídos simultaneamente, na cidade de Santos/SP - Brasil. O estudo da interação solo–estrutura entre os edifícios do grupo e o maciço de solos utilizou a metodologia de CHAMECKI (1956), onde a superestrutura é modelada como pórtico espacial elástico linear e, o solo é modelado como meio elástico estratificado conforme AOKI e LOPES (1975). Estudos paramétricos demonstram a influência da rigidez da estrutura, do efeito de grupo entre as fundações superficiais, do processo construtivo e das construções vizinhas, na configuração final dos recalques

Abstract in English
This work presents a methodology for the soil-estructure interaction analysis of a group of buildings on shallow foundations in soft clay soils. The long term behavior of clay is modeled by Kelvin’s rheological model. Model parameters is evaluated by back-analysis of measured settlement – time curves. The soil–estructure interaction is based on CHAMECKI (1956) model, where the superstructure is modeled is a spatial elastic linear frame and, the soil is modeled is an elastic linear stratified half space according to AOKI & LOPES (1975). Parametric studies shows the influence of the superstructure stiffness, the interaction among buildings foundations, and the effect construction steps in the final settlements configuration
