Abstract:
A procedure for design of concrete silo walls subjected to asymmetric flow patterns is presented. Differences between concentric and asymmetric flow for both the mass flow and the funnel flow cases are discussed. A method of computing differential wall pressures resulting from flow channels is presented along with guidelines for selecting design flow channel geometry and creating a practical silo design for asymmetric flow. Design aids (based on finite element modeling) for estimating circumferential moments are included. Two silo design examples are presented; one for grain and one for coal.
