I'm planning on building some very tall (and medium tall) columns to hold platforms. Having poured over the literature for several weeks, I've still not found information on built-up columns (i.e., mechanically laminated two-bys) that include a variation on the theme of "hog-troughing," a term I've seen on this site from time to time. Does anyone out there know of any literature on built-up columns that include the attachment of members to the built-up studs laterally, that is, as if one were building a sort of modified "I-beam." I have no structural standards to point to, but it seems to me that adding studs to the edges of a built-up column would give that column greater resistance to buckling along the weak axis. Is this just my imagination? I would love to hear the voices of experience wax eloquent on this theme before I commit!
