Análise da geometria ótima para o dimensionamento de sapatas

Abstract

In the field of civil construction, it is extremely important that the structure of residences and buildings are stable, guaranteeing comfort and safety to people. In order to guarantee this, it is necessary that the building is securely fixed to the ground, through elements known as foundations. Among them, there is a type called rigid footing, widely used in soils with high resistance in their first layers. Given its wide use, this research calculate its sizing and budget relativizing its geometry, which can be square, homothetic (proportional to the column) or with equidistant edges (same distance between the face of the column and the footing), evaluating hypotheses with centered and momentum esforces, comparing the theoretical, semi-empirical and empirical methods to obtain the admissible soil tension to determinate that the square geometry presented a lower cost according to the adopted parameters.
