p. 90-101Silos are widely used in food industries to store different types of agricultural products.
Loads exerted by the stored material on silo walls are critical in the design of the shell
structure. Eurocode standard represents these loads by means of symmetrical pressure
distributions and unsymmetrical pressure distributions, this latter named patch-load. In this
paper, the structural effects of the patch load are investigated. A 3D FEM model has been
developed to model cylindrical flat bottom silos made of corrugated steel walls. Firstly, silos were modelled only with the effect of the symmetrical pressure distributions. The
structural effects at this stage were compared to those obtained in a second stage, where the patch-load was introduced in the model. The purpose of this research work was to understand the structural effects of the patch-load as described in the Eurocode, as well as validate analytical expressions to determine these effects more easily.Ayuga, F.; Gonzalez-Montellano, C.; Gallego, E.; Fuentes, JM.; Ramirez, A.
