X-bracing connection bolted vs welded
X-bracing connection bolted vs welded
(OP)
I am curious what the general preference is in connecting x-bracing (tension only) members to gusset plates. The general question is bolted vs. welded. I tend to think that bolts are generally easier/faster to install than welds, and therefore cheaper. If bolts are used, then can they be snug tight with standard holes, or would erection tolerances dictate that they have to be oversize holes and pretensioned bolts (would I have to go so far as calling for slip-critical with faying surface preparation)?

Shop weld and field bolt is good advice.

If you use bolted, keep in mind that braces are often fabricated intentionally short by a small amount. I think 1/16" is common. Somebody pointed out a mistake(?) that I made once by showing oversized holes to help with fitup. The supposed mistake was that the oversized holes negated the intention of the short brace fabrication. Not sure either way, but it's worth mentioning because some of the others typed about oversized and slotted holes.
