ESTUDO DAS FUNDA ES DE UM CASO DE OBRA EM ESTACA RAíZ ENVOLVENDO A INTERA O SOLO X ESTRUTURA

This paper presents the analysis of a case history contemplating settlement monitoring sincethe beginning of construction. The building is founded on root piles on a sandy deposit. The analysisincludes relevant aspects concerning the structure modeling and the soil behavior. A comparison is madebetween the common design procedure in which the structure rests on fixed supports with a much realapproach considering the supports susceptible to settle. The last approach allows relevant aspects of soilstructure interaction to be accounted for, including the effect of load redistribution, tendency to settlementsequalization and a more realistic behavior of the foundation performance. Settlement monitoring also allowsthe adjustment of soil compressibility modulus and a direct comparison between predicted and real behavior
