Duwe6 - OK. I think I got the idea from Megyesy "Pressure Vessel Handbook" 12th ed p 100 Saddle for Support of Horizontal Vessels where he says "At the sliding saddle the nuts of the anchor bolts shall be hand-tight and secured by tack welding." The word "shall" led me to think it was code...
In addition to large displacement, consider using "notional loads" in AISC Steel Construction Manual 13th ed Appendix 7 page 16.1=196. They are applied simultaneously in both lateral directions, in addition to the lateral load, and are related to the gravity-type loads. N=0.002* gravity load...
I have anchored the centers of the two support channels, one on each side. I have slightly oversize holes in the center regions to absorb earthquake but allow some thermal growth. Other bolt holes are slotted for thermal growth. But if someone during erection whacks the bolts with a slug...
I (think) I read in ASME VIII div 1 somewhere that to accomodate thermal expansion I can specify finger tight bolts with the nuts staked or tack-welded to the bolt to prevent accidental overtightening. What section is this in? 2007 VIII div 1 nonmandatory appendix S is obviously not the right...
