Weep holes for tubular structures
Weep holes for tubular structures
(OP)
Ok, I give up. Where in D1.1 does it say tubular structures need weep holes? I can't find anything on it from AISC, either. Any AASHTO comments on it?

From SCOSS; "Although the structural elements are manufactured as 'sealed units', continuous welding does not necessarily produce a complete seal and water may accumulate inside where the units are exposed to the weather".

The accumulated water apsix mentioned will bulge the tubes when it freezes.

Even if your welders are perfect, someone will later drill an attachment hole for some minor component on a horizontal top surface and there's your water ingress point.
If you're in a climate that EVER freezes, drill the holes!

Holes are never at the bottom and are often burnt rather than drilled.
As a non-structural engineer, if I were building my own house from hollow sections, I would drill and tap vent holes and use a threaded plastic plug. I would use the holes for inspection and for pressure testing if I was worried about water ingress. I would use the hole for introduction of a vapour phase inhibitor and for the location of a humidity indicator.
