Supporting steel silos on discrete, eccentric brackets offers an attractive alternative to using traditional ring beam supports in terms of both cost and simplicity of construction. A range of silos of typical geometries are analysed and the structural behaviour presented. Collapse modes are found to include buckling, plastic collapse and combined mechanisms. The results of a finite element parametric study that considers the effects of bracket width, bracket height and geometric imperfections are then presented. It is found that the strength of bracket-supported silos, is strongly but non-linearly dependent on bracket width. Increasing the bracket height also increaes the silo strength. Bracket-supported silos are found to be generally imperfection insensitive. However, a weld imperfection placed above the bracket can result is significantly increased strength.
