ABSTRACT
Cylindrical shells made of steel corrugated sheets with vertical stiffeners (often referred to as columns) are relatively common in use as storage structures for grain in agricultural industry. Thin corrugated sheets have horizontal folding, and their resistance in the vertical direction is relatively small and usually omitted in design. In such cases it is assumed usually that the entire vertical loading in cylindrical shell is carried out by vertical stiffeners which are fastened to corrugated sheets by bolts. Said vertical load is mostly produced by material friction to the walls of a silo but also from the weight of roof structure and other loads i.e., loads from transporting equipment or other appliances placed on the silo roof as well.
