Influence of specific weight and wall friction coefficient on normal pressures in silos using the Finite Element Method

The objective of this work was to develop models using the Finite Element Method (FEM) assess maximum normal pressures in static condition silos different wall friction coefficient and specific weight stored product compared obtained by Eurocode 1, part 4. geometries were developed based on dimensions experimental station at Universidad de Leon (Spain). material properties Jenike shear cell tests used generate MEF. 3D generated varying (0.2, 0.4, 0.6) (6; 7.5 9 kN / m3). It verified that FEM follow theory silos: increase due decrease coefficient. Moreover, pressure occurs hopper silo transition. (FEM models) with 4 allowed validate developed, presenting trends similar values those found demonstrated influence significantly interferes slender silos.
