A practical method of manufacturing, assembling, and constructing a single silo or building or a cluster of polygonal storage silos using a column comprising horizontally-arrayed structural column panels. A structure built with these columns can be constructed using a cost-effective and relatively safe method of lifting. In addition, three or more of these structural columns can be connected together with wall panels or beams to fashion a polygonal compartment or multiple polygonal compartments, to serve as structural support for heavy loads, as a process tower for supporting equipment, a multi-story building for human occupancy (such as an apartment complex), or as bulk storage silo(s). The column can join standard and customized beams and wall panels. Columns can be attached to wall panels of round structures, to serve as stiffeners, or to the sides of polygonal structures, to serve as side-wall supports.
