Soil-structure interaction analysis considering concrete creep and shrinkageInteração solo-estrutura: análise contemplando fluência e retração do concreto a Fluminense Federal University, Civil Engineering Department, , Niterói, RJ, Brazil; b State University of Rio de Janeiro, Structure and Foundation Department, Rio de Janeiro, RJ, Brazil. Abstract ResumoThe paper presents some results from Rosa's [1] research that aimed to verify the effect of creep and shrinkage of the concrete in soil-structure interaction. The construction consists in a 17 storeys building. It is set down on shallow foundation, in the central part of the construction, and steel piles, on the boundary. The structure was submitted to instrumentation during construction, including the monitoring of foundation settlements and columns deformation. It was possible to compare the structural design with a numerical refined structural analysis. Comparisons of the structural and foundation design with and without due consideration of soil-structure interaction are also presented. Finally, the different design assumptions were confronted with instrumentation results, both related to foundation settlements and to columns loading as well. Attention is pointed out on the effect of concrete creep and shrinkage in the soil-structure interaction analysis.Keywords: soil-structure interaction, foundation settlements, instrumentation.O presente artigo apresenta alguns resultados da pesquisa de Rosa [1], que teve por objetivo verificar o efeito da fluência e retração do concreto na interação solo-estrutura. Foi analisada uma edificação com 17 pavimentos mais subsolo, em fundação mista, submetida à instrumentação de campo contemplando o monitoramento de recalques e deformação de alguns pilares, ao longo do processo construtivo. Foi possível comparar o projeto do calculista com uma análise numérica mais refinada. Também se comparou o projeto, sem considerar e considerando a interação solo-estrutura. Finalmente, os diferentes cenários de projeto foram confrontados com os resultados experimentais, tanto em relação aos recalques como aos esforços nos pilares instrumentados. Atenção particular foi dada ao efeito da consideração da fluência e retração do concreto na análise da interação solo-estrutura.Palavras-chave: interação solo-estrutura, recalque, instrumentação.
