Abstract

The actions and assumptions for structural analysis of reinforced concrete grouped silos (called also silo batteries) are not precisely specified in technical references and relevant standards of design. The internal forces appearing in the cross-sections of cylindrical silo battery walls due to silo pressure may be evaluated by superposition of symmetrical actions and free patch load representing accidental asymmetries of pressure. The paper deals with the numerical analysis of sectional forces and moments in R C cylindrical silo battery subjected to silo pressure and patch load, taking into account a silo bin model that includes the interaction between the wall structure and stored particulate solid.
