fire protection of epoxy anchor

fire protection of epoxy anchor

fire protection of epoxy anchor

(OP)
I am using a MC18 bracket attached to existing column face with epoxy anchors. the bracket supports major girder beam of the floor above. the bracket will be painted with intumesent fire resistive paint to provide 2 hours of fire proofing. the question is this.
does fire proofing the bracket also fireproofs the epoxy anchors?

thank you for your thoughts.

RE: fire protection of epoxy anchor

HILTI Product Technical Guide shows 50% reduction for adhesive (epoxy) anchors for temperature of 220 deg F. On another hand, expansion anchors do not have this reduction. I would think that expansion anchors require the same fire protection as other steel.

I would call HILTI (1-800-879-8000 in US or 1-800-363-4458 in Canada) and ask them. They should know.
