Fire Protection and Steel Beams
I am reviewing a renovation and change of occupancy for a small 2 storey mixed use building. It is wood frame construction with the second floor supported on steel I beams. The original construction had no fire separations or fire resistance ratings, the new construction will require the floor and suite separations to have 45 minute fire resistance ratings.
The code I am using (BCBC) has several options for fire protection of individual steel beams, and the proposed method is portland cement-sand on metal lathe that fastened to metal channels held in position by metal wire.
I am unfamiliar with the constructability of this method, has anybody else used this or dealt with this? Would this be a sprayed application or troweled on?
Any feedback would be appreciated. Thanks!
