Ring Beam Stiffness Criterion for Column-Supported Metal Silos
This internationally co-authored paper presents the first generic, algebraic, rigorous, verified criterion to determine the required ring stiffness of discretely supported cylindrical metal silos.
Column supports apply local loads to a shell, producing stress concentrations and potential buckling failures. A ring beam cannot easily redistribute these forces because beams are far more flexible than membrane action in shells. A subsequent paper by these authors identified the ideal height of a secondary ring and solved the problem for lower rings (DoI:10.1061/(ASCE)EM.1943-7889.0000688). These landmark works resolve this long-standing silo design problem (thomas.ummenhofer@kit.edu, Jin-Guang Teng cejgteng@polyu.edu.hk). Rotter chairs the Standards Committee EN1993-4-1.
