I think that there's a whole raft of things that are available that sort of
presume that the installer/user knows what they are doing (which may not be
the case). This is especially true with structural stuff.
Steel I-beams don't come with instruction sheets, nor does structural
pipe. Even some more specialized stuff (screw anchors come to mind)
doesn't seem to have any sort of handy "applications note" (at least not
when I was looking for it). We just told the folks installing the anchors
the loads we needed to deal with, and they selected an appropriate anchor
and installed it. For that scale, it's a pretty specialized operation. I
seem to recall that there was really only one firm in the greater Los
Angeles/Southern California area that did this kind of work (the name began
with a B, I think, in case someone's looking for such things).
I'd hate to have to try and figure out the strength of such a thing from
first principles.
