Resumo: The objective of this work was to develop models using the Finite Element Method to evaluate the maximum normal pressures in the static condition in silos, varying the specific weight and the friction coefficient of the stored product and later comparison with Eurocode 1, part 4. The models of silos were based on the geometry of the experimental station at the Universidad de Leon (Spain). The material properties were obtained by Jenike shear cell tests and compared with Eurocode pressures. 3D models were generated varying the friction coefficient (0.2, 0.4 and 0.6) and the specific weight (6; 7.5 and 9 kN / m3). It was found that the models correspond to what is expected in view of the theories: normal pressures increase due to the increase in specific weight and decrease due to the increase in the friction coefficient. It was found that the maximum normal pressure occurs at the hopper silo transition. The comparison with Eurocode 1, part 4 made it possible to validate the models developed, presenting values ??close to and lower than those found by the MEF. The influence of the friction coefficient and specific weight (within the range of the main Brazilian agricultural products: corn, soybeans, wheat, rice and feed) significantly interferes with the pressures in slender silos.

The influence of the friction coefficient and specific weight (within the range of the main Brazilian agricultural products: corn, soybeans, wheat, rice and feed) significantly interferes with the pressures in slender silos.The objective of this work was to develop models using the Finite Element Method (FEM) to assess the maximum normal pressures in the static condition in silos using different wall friction coefficient and specific weight of the stored product compared to the pressures obtained by the Eurocode 1, part 4. The geometries of the silos models were developed based on the dimensions of the experimental station at the Universidad de Leon (Spain). The material properties were obtained by Jenike shear cell tests and were used to generate the models by the MEF. 3D models were generated varying the friction coefficient (0.2, 0.4, and 0.6) and the specific weight (6; 7.5 and 9 kN / m3). It was verified that the models by FEM follow the theory of pressures in silos: normal pressures increase due to the increase in specific weight and decrease due to the increase in the friction coefficient. Moreover, the maximum normal pressure occurs at the hopper silo transition. The experimental pressures (FEM models) compared with Eurocode 1, part 4 allowed to validate the models developed, presenting trends of similar values to those found by the MEF. The experimental models demonstrated that the influence of the wall friction coefficient and specific weight significantly interferes with the pressures in slender silos.Universidade Federal de Viçosa - UFV2021-08-31info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufv.br/reveng/article/view/1233610.13083/reveng.v29i1.12336Engineering in Agriculture; Vol. 29 No. Contínua (2021); 192-203Revista Engenharia na Agricultura - REVENG; v. 29 n.
