Stability behavior of column-supported steel silos with engaged columns

Publisher Summary The chapter discusses the stability behavior of column-supported steel silos with engaged columns. Supporting silo walls directly on engaged columns provides a simple and cost-effective support arrangement for light steel silos. Numerical analyses, including the linear eigenvalue buckling analyses (LEA) and the geometrically nonlinear analyses (GNA), are carried out to investigate the stability behavior of column-supported steel silos with engaged columns. The effects of geometric parameters, including the radius-to-thickness ratio and the width and the length of engagement of the column, on the structural behavior are analyzed in the chapter. It is found that the buckling strength of column-supported silos is mainly dependent on the engagement length of the column, which also affects the buckling deformation mode. To improve the load-carrying capacity of column-supported silos, the column should be engaged into the silo wall as far as the eave.
