Fire Rating
Fire Rating
(OP)
For a steel framed building that uses braced bays as lateral system, is it fair to assume that the braces are not part of primary structural system from fire-rating perspective. My argument is based on the assumption that during a fire event, the building can rely on the restraint in beam-beam and beam-column connections for it's lateral stability even if the braces had been compromised. Is that a reasonable argument? Appreciate your input. Thanks.

Have you actually checked your system and connections to prove that it holds up under the load it would see during fire without the braces?
