I thought I?ve seen fireproofing weighing anywhere from 15 pcf up to 40 pcf (Grace FP Products). Assuming a W18x35, surface area (minus top of top flange) = 4.34 sf/ft (AISC Manual). For each inch of FP, weight of FP = 5.5 plf to 14.5 plf. Depending on how much FP, average weight is probably at most in the 2 to 3 psf range and I generally lump that into the ?Miscellaneous? load. Special situations might require a closer look.

practically zero. If the spray on fire protection is more than two or three pounds per linear foot on a 24" beam I would be surprised. Typically spray on is accounted for in the miscellaneous loading. If the spray on is a factor in the beam design, you are cutting things way too close. :-)

Anybody got a good rule of thumb uniform dead load for sprayed on fireproofing of steel beams?
