Bolting through HSS's
Bolting through HSS's
(OP)
Does anyone know if AISC has any specific rules about using a through bolt in a HSS member? I've seen it done in aluminum tubes and you can actually crush the tube if you tighten the bolts too much.

Yes, that is what we do. The sleeve is there to allow the bolts to be tightened. For large shear loads, it is sometimes necessary to add a doubler plate on the face of the HSS to distribute the force, but then the two members are not flush.

The sleeve idea seems like it would be really labor intensive. Do you do this because you can't weld in the field or have you actually found it to be cheaper than welding?

We have specified the same sleeves in new york state.
We do this partially for strength and partially for durability as water can get inside the tubes when there is no sleeve.
The only problem is that it is difficult to allow tolerance in this connection.

CWIs don't need that kind of talk. we've got mouths to feed. Welders do good work. only 1 out every 10 field welds i fail is for bad quality. The other 9 aren't there to judge.
