Connections to Fireproofed Beam
Connections to Fireproofed Beam
(OP)
W21 beams supporting concrete slab. Architect/client would like to provide an angle ledger off of the web of the W21 to support 3x wood joists that are aesthetic only, i.e. it will look like an industrial steel and timber type ceiling but the wood is not actually structural. Do the angles connected the web of the steel require fireproofing over their entire area? If so is there any way to make such a connection, wood (obviously not fireproofed) to steel that does need to be fireproofed? Is there some standoff distance/length that fireproofing needs to be extended along connected members?

How are they getting the fire rating on the W21? The spray on foam? You could just foam the angle as well and then remove the foam off of the bearing surface for the wood connection. Not sure if that would fly with the AHJ.

I did answer that last night. It is hard to do this without (at least) looking at sketches.
