Fire Rating of Concrete-Filled HSS Column Sections
Fire Rating of Concrete-Filled HSS Column Sections
(OP)
I am designing exposed exterior HSS18.000x0.500 columns to support a roof above an interior atrium space. Since the columns are visually exposed and also exposed to the elements, I am reluctant to recommend intumescent piant for fire protection as it will experience UV degradation over time. I have recommended filling the columns with concrete as an alternate to intumescent piant; then simply painting the columns a weather resistant grade of paint.
Can some one direct me to where/how I can qualify the fire rating of the resultant composite column sections?
Thanks, in advance.

Have you tried searching ACI publications?

How about dropping a cage of rebar in there and making it a concrete column with steel cladding?
