| dc.description.abstract | Silos are storage structures for solid products, such as in agriculture, soy, corn, beans, among many others, with the purpose of guaranteeing the quality and durability of the products stored for a long period of time. Although they are important structures in the flow of production, in Brazil there is a deficit, which increases every year, as the speed of production growth is greater than the speed of investments and research in storage units. The bases and foundations of silos suffer a very high load variability, since the loading and unloading of grains occurs quickly, this often causes deformations that compromise the safety of the structure. As it is known that some foundation systems are little used despite their benefits, we can observe this in silos. The piled radier is a system of foundations that is little used due to its greater difficulty in calculating, but it brings several benefits for the execution of silos, as it reduces the expected settlements and reduces the cost of foundations, as it optimizes the number of piles necessary to ensure the overall rigidity and stability of the silo. To further improve efficiency and have comparative parameters for new projects, the present work aims to study the interaction between soil-structure for flat-bottomed metallic silos, aiming to optimize the use of piled radiator. The analysis is based on the comparison between computer simulations, the existing structural design and a brief design of the number of piles, using a real SPT report for the correct validation of the results. The comparison between a quick analysis of the amount of piles needed and the structural design shows that the design is within reality, considering the design parameters. | |
