Diseño y análisis mediante simulación de un silo de fondo cónico de 100 m³ de capacidad para la industria alimenticia, en plancha lisa de acero estructural ASTM-A572 GR50

Abstract

The increasing trending in food storage, due to the growing population and the unfavorable climatic factor in some areas, produces an engineering issue in the structural area, trying to reach the most stable system and with material optimization, the focus of this research extends to the design of a conical hopper silo using standards such as: EN 1991-4:2006, ASME BPVC section VII, API 650 and a subsequent validation through ANSYS software where pressures between 39.09 and 66.76 kPa can be appreciated for the vertical wall and the hopper, respectively, which results in the selection of 5mm sheet plate in ASTM A572 Gr50 with a minimum safety factor of 8.34, which means an extreme conservatism by the aforementioned standards, coming from the generality of the methodsthat cover the design of silos and tanks , otherwise, the braced support structure is worked with the matrix method of stiffness and slenderness selection, which allows the selection of profiles with a FS of 1.46, guaranteeing a functional and economically optimal model.
