Discharge buckling assessment of slender silos considering different forms of Eurocode patch load

Thin -walled silos are one of the major storage structures in most of industrial and agricultural sectors. Due to small wall thickness of steel silos, they are susceptible to buckling failure. Discharge process of ensiled materials typically result in some sources of asymmetry in the pressures imposed on silos walls. EN 1991-4 cover this issue by introducing patch load concept as an additional load that should be considered in discharge design of silos. This study investigates the buckling capacity of an example slender silo by taking into account two different forms of patch load proposed in the Eurocode
