This study investigated the theoretical lateral design pressures, vertical frictional forces and bending stresses exerted by shelled corn on a wall configuration made of folded steel plates. Silo walls panels with trapezoidal corrugations were considered. Lateral design pressures and vertical frictional forces were calculated by using Janssen’s equations for pressures in deep bins and bending stresses exerted by ensiled corn were calculated by using principle of engineering mechanics. Inclined sections of corrugations with 135º from the horizontal plane had the highest lateral design pressures and vertical frictional forces. Corrugations with tie bars had significantly lower bending stresses than the corrugations without tie bars. Using the results of this theoretical work, further studies can be performed for a complete silo model with a roof structure and a hopper bottom and wind forces and the shear stresses can be added to the model. This may give a better interpretation of the theoretical results on real models.
