Análise de fundações tracionadas com aplicação da teoria bayesiana

Abstract

The Soil Mechanics area brings with it a range of uncertainties, in particular regarding to foundations. Some uncertainties are due to loading conditions, peculiarities in construction processes, field investigation data and soil variability, among many others that may directly influence the bearing capacity of the foundations. When it comes to foundations under no conventional forces on construction, as is the case of uplift loads, these uncertainties become higher, whereas the dubiety and the adaptability add up to the above mentioned conditions of calculation methods. The present research objective is the presentation of different calculation methods to tensile foundations and the reliability study of these methods with conceptual and scientific analyses. In this process, will be performed by means of the Bayesian Theory, using the updated uplift load test data. Several observations can be made about the available methods to foundations submitted to uplift loads and the corresponding applicability to each type of foundation, like shallow or deep foundations. The continuity of this study can direct to the improvement of calculation methodologies to bearing capacity of different types of tensile foundations and, then, a greater security.
