Fire Rating UL v other
Fire Rating UL v other
(OP)
I was recently told by an architect that if you are using a fire rated assembly other than UL rated assmeblies you need to de-rate the load capacity by 20%. I am in the US, and have not heard of this before. I found references to some things in Canada, but that is it. Anyone heard of this before?

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

There are some load reductions in joist capacities for UL ratings with spray on fireproofing but the loads are listed in various UL assemblies. Could this be what he is referring to? Get a reference from him......
