RE: Joist girder stabilizer plates in existing building

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Aren't roof joist girder stabilizers there for the same general reason that continuous bottom chord bracing for joists are supplied, for uplift wind pressure loading? Like Harold said, this puts the bottom chord into compression and unlike the top chord that is braced by deck the bottom chord needs to be braced. There would also tend to be rotation and movement at the ends, thus the stabilizer plate.Something intuitively says the plates also help in gravity loading to keep the bottom chords from "kicking out". I am not a joist designer so I stand to be corrected..
