The non-woven geotextiles are used in the separation of the layers of pavements to avoid the contamination of the materials and the weakening of the structure. In order to study the behavior of different non-woven geotextiles in pavements an equipment has been created made up of a bipartite cylinder of 20 cm in diameter and 37 cm in height, where the materials are deposited in layers, initially the floor of the subgrade, then the geotextile and the gravel that simulates the base. On top of the l...

O presente trabalho lida com A presente trabalho trata do estudo da resistência ao cisalhamento de materiais granulares não coesivos, enfocando no aspecto especificamente o processo de determinação do ângulo de atrito do material. Utilizou-se, como material representativo do comportamento de solos granulares, esferas de vidro, cuja forma dos grãos é padronizada. Foram realizados ensaios de caracterização das esferas de vidro, para três diâmetros nominais (A072, A120 e A170) com distribuição gran...


ELECTRONIC SPREADSHEET FOR THE CALCULATION OF THE LOAD BEARING CAPACITY AND ALLOWABLE STRESS OF THE SOIL FOR ISOLATED FOOTING

  • Bruna Leal Melo de Oliveira

For geotechnical design of shallow foundations it is necessary to know the allowable stress of the soil, obtained indirectly from the load bearing capacity; or directly, applying the semi-empirical methods. An alternative to automate these calculations is the use of spreadsheet, a simple tool, aiming to optimize time and reduce human error. To demonstrate the applicability and effectiveness of this tool, a spreadsheet was developed using the Microsoft Excel software, based on some variables such...
