Özet

In this study, finite element analysis approach was used to investigate the displacements and bending stresses exerted by shelled corn on a wall configuration made of folded steel plates. Silo walls panels with trapezoidal corrugations were considered. Entire bin geometry was created with finite element approach; loads calculated by using Jansen’s equations for pressures in deep bins were applied over the bin geometry. Resultant displacements and bending stresses were evaluated by using the plots generated by finite element analysis software. The highest bending stresses occurred at the corner of each wall panel with greater bending stresses occurring around the tie bars. The highest displacements were observed at mid-points of wall span. 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.
