Análise de interação solo-estrutura em edifício de concreto armado: estudo de caso

Abstract

By considering the properties of the soil where the structure will be built and how it reacts to it, the soil-structure interaction becomes necessary for any project. The use of this artífice allows projects to be closer to reality, making it possible to carry out a more refined analysis and a more optimized sizing. This work uses the TQS software for modeling and analysis of na 8-story building in reinforced concrete, analyzing the behavior of global stability, maximum displacements, efforts of bending moments in beams and columns and support reaction when considering the soil interaction structure. It was verified that the global stability has an increase in its efforts when considering the soil-structure interaction, confirming the numerous studies in the area and, as a consequence, the maximum displacements tend to have the same behavior. For the beams, it was observed that the central spans were the most requested and the external spans the least influenced by the soil-structure interaction. In the case of study, the requesting efforts on the pillars concentrate their greatest efforts on the base of the pillars, for the directions of 0o and 90o, being more expressive in intermediate pillars. In the analysis of the support reactions, it was noticed that the efforts tend to be smaller in the center of the building when considering the soil-structure interaction and greater as it moves towards the end.
