Resumo: | The assumption of perfect supports (fixed or pinned foundations) for the boundary conditions of reinforced concrete buildings has been used for many years by structural engineers. This fact is mainly attributed to the great difficulties faced in the past, when designers needed to calculate buildings by using manual methods. Nowadays, realistic analysis that takes into account the deformability of the adjacent soil foundation is possible, based on the development of powerful computers and computational software packages. However, many structural engineers still use the same simplified boundary conditions widely used in the past. The main explanation for this problem may be the lack of information and models available in the literature, as well as the lack of interaction between structural engineers and foundation engineers. In this context, the present paper aims to present practical recommendations for applying the soil-structure interaction. Additionally, based on some practical examples, this paper shows that the rigid support hypothesis may lead reinforced concrete columns to significant force distortions. |

Tal fato se deve, principalmente, à grande dificuldade que se tinha no passado em analisar manualmente edifícios sobre apoios flexíveis. Porém, com a chegada dos microcomputadores e com o desenvolvimento de diversos programas computacionais, já se pode usufruir de análises mais realistas, que levam em consideração a deformabilidade do solo adjacente às fundações. No entanto, observa-se que os engenheiros estruturais continuam utilizando o mesmo modelo simplificado do passado, provavelmente pela falta de informações ou talvez pela falta de maior interação com os engenheiros de fundações. Neste contexto, o presente trabalho tem por objetivo apresentar recomendações práticas para a aplicação da interação solo-estrutura. Adicionalmente, demonstra-se que a hipótese de apoios totalmente rígidos pode levar a importantes distorções nos esforços obtidos para os pilares de edifícios em concreto armado pelos exemplos práticos.Universidade Estadual De Maringá2008-10-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/546710.4025/actascitechnol.v30i2.5467Acta Scientiarum.
