Vertical silo pressure analysis with unusual building materials

With the incapacity in the Brazilian storage network, leveraged by the constant increase in national agricultural production, the construction of a silo becomes essential, where some of the problems in its dimensioning are the distribution of pressures of the product stored in the construction material. Thus, the present work aims to determine the pressure exerted by bean cultivars, according to EUROCODE 1. The experiment was conducted at the Laboratory of Rural Constructions and Ambience - LACRA of the Federal University of Campina Grande, in the municipality of Campina Grande- PB, analyzing the different types of beans: carioquinha (Phaseolus vulgaris L.), black (Phaseolus vulgaris L.) and macassar (Vigna unguiculata). We analyzed the physical and flow characteristics of the products, and used two unusual materials for silo sizing, acrylic and wood, determining the pressures exerted by these cultivars in the storage silo, based on Eurocode 1. It was concluded that the products are classified as coarse grains, with free flow, the pressures exerted by the product are consistent with the norms established in the Eurocode 1 standard, considering all the suggested safety factors.
