Abstract: A shell silo is supported with its bottom stage clear of the ground by means of support legs which are secured to flanges integral with the longitudinal edges of shell sections. The legs are secured in this way to at least the bottom stage and, where there are three or more stages or rings, also to the third stage, the sections of alternate stages being aligned with one another. The legs may be formed of a hollow cross-section member having a projecting strip or flange through which the connection to the flange of the shell section is made, and a separated backing strip may also be provided.
