Projeto de um silo em concreto armado para armazenagem de farelo de soja: estudo de caso das pressões de paredes.

Abstract

Brazil has an extensive agricultural production capacity, with significant improvement in recent years. The agricultural sector has the issue of expanding the storage capacity for food grains and their processing following that development. Concrete silos structures have been used all over the world for proper and safe dimensioning. It is necessary to know the behavior of the pressures that the product exerts on the vertical walls and the walls of the hopper. The assessment of the efforts acting on the structure of a silo caused by grain or bran occurs based on foreign standards. The work presents the calculation of the wall pressures caused by the filling and unloading of soybean meal from a reinforced concrete silo of predefined dimensions (cylindrical silo with flat hopper) and performs the calculation of winds according to the Brazilian standard. A software for Finite Element Method (FEM) calculation was used to calculate the wall efforts, thus being able to carry out and conclude the verification of the reinforcement design of a section of the silo wall, located at its intermediate level.
