Abstract :

In this study, the optimal dimensions of the silo were investigated for barrel-type cylinder, conical outlet, steel construction silo which used in Tombul hazelnut storage in the Giresun province conditions. 10, 11, 12, 13, 14, 15 ve 20 mm wall thickness for 1635 tons storage capacity silo were examined in the study. For this purpose, pressure loads acting on the silo wall surface at filling and discharge conditions (vertical, horizontal, friction traction pressure load) using Eurocode 1 and Australian standards were calculated for different wall thicknesses and this calculated pressure loads by entering in ANSYS finite element software program, stresses which occurring in different directions on the surface of wall was determined. Results the study, it was determined that 10, 11 and 12 mm wall thickness were not reliable in terms of stresses caused vertical pressure load in the filling conditions.The optimum wall thickness will not lead to any structural problem are emerging as the silo which was found to be suitable 13 mm wall thickness when considering storage capacity and the maximum von Mises stresses. This silo using Tombul hazelnut storage with barrel-type cylinder and conical outlet shows the most appropriate features in terms of engineering. At the result of the analysis according to Australian standard (AS 3774) of proposed this type of silo in terms of pressure loads acting on the surface of the silo wall was observed to be reliable.
