Avaliação solo estrutura no comportamento de um edifício de alvenaria estrutural - Estudo de caso

Abstract

This work is an analysis of the consideration of the soil-structure interaction (ISE) on the elements of masonry structures. For this study, two models were used, one with theoretical support and the other considering a soil-structure interaction. In both models, a direct radier-type foundation was considered, changing only the support of the structure. In most structural calculation offices, theoretical support, labels or bezels are used to facilitate the analysis of the structure. However, these models can provide results incompatible with reality, as they do not take into account the deformity of the soil, on which the building will be built. Thus, for an analysis that approaches reality, software was developed that takes into account soil deformation. In this work, a numerical modeling of a structural masonry building with 15 (fifteen) floors was carried out, in which it considered the vertical and horizontal actions acting on the building. Use SAP 2000 software that uses the Finite Element Method. For the recognition and characterization of the local soil, a real survey report (percussion survey - SPT) from the state of Maranhão in the region of Rosario was used. With the geotechnical profile of the site, it was possible to recognize the soil layers that compose it and the characteristics of each one of them. The results generated demonstrate the importance of considering soil deformation even though the simplest way to replace theoretical supports. For a more adequate structural analysis, it is recommended that a soil structural analysis be evaluated.
