ESTUDO COMPARATIVO DE CONSUMO DE MATERIAIS DA FUNDAÇÃO DE UM EDIFÍCIO RESIDENCIAL ANALISANDO TIPOS DE FUNDAÇÕES DISTINTOS: Bloco sobre estaca e Tubulão

Abstract

The following paper presents a case study aiming at comparing the consumption of materials to be used between two types of foundation: pile block and pipe. It will be made from a project of a residential building of 5 floors, prepared by the author himself. In this study, we sought to know the types of foundations under study, as well as their advantages and restrictions, the main materials (concrete and steel) constituting the systems, the actions that act on the structure, as well as the increase and reduction coefficients, combinations the actions and the path they take to reach the foundation elements, as well as the geotechnical data needed for the dimensioning of the elements and the verification of the need for structural elements that help the foundations, such as the crowning blocks. As it was not possible to conduct surveys on the adopted terrain, for classification and verification of stratigraphic soil profiles, survey bulletins were adopted through the SPT test. The proposed methodology demonstrates the appropriate forms and methods for sizing each foundation. After sizing and detailing it became possible to make the comparison, in which spreadsheets were made with the quantity of steel and concrete of each system, thus indicating the differences in consumption. Thus, it can be concluded that both systems would serve similarly to the work
