Fireproofing tube steel.
Fireproofing tube steel.
(OP)
I have a condition were an exterior girder abuts a stairwell. As a result I have an lu of 15ft. I would like to use a HSS section to minimize the width and keep the section in the plane of the wall studs. However, the Architect does not know of any approved UL ratings for this assembly. This does not make sense to me because the fireproofing requirements are based upon the ration of weight to heated perimeter, and a tubes ratio will significantly greater then a WF hence better fire resistance. Has anyone had this issue? How was it addressed?
Thanks
Thanks

Other than that, I'm aware of intumescent coatings that I've used for mezzanine areas.

If the architect does not want to thicken the wall to incorporate a thickened fire protected column, would use of intumescent fire protection coatings work?

In general the column UL tests are more restrictive than a beam test would be and are therefore applicable (and conservative) to the occasional HSS beam.
