Validação de programas computacionais para cálculo de tensões de contato em sapatas isoladas

Abstract

The footing foundation solution is one of the most widely used philosophies in Brazil, and therefore, knowledge on this topic is fundamental for the good practice of engineering. This work aims to assess the accuracy of computational programs compared to the manual calculation of stress at the base of footings (contact stress). It can serve, in the future, as a reference for the design of shallow foundations using the programs and methods to be explored throughout the work. The methodology is based on research from recognized bibliographic sources in the field of foundations, with renowned authors in civil engineering, in addition to presenting practical content with an operational view. The result obtained will also serve for comparisons with

similar research, reinforcing or diverging from debated theories. It is a challenge for the engineer to choose which calculation method to use to obtain the stress at the base of the designed footing, as they often use computational programs. Therefore, this research aims to validate two of the most used programs in Minas Gerais: one from the company Mudados and the other developed by Dílio and Élvio, the latter being the advisor of this work.
