Re: Ordinary Truss Moment Frame

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Quoting "Gerard Madden, SE" <gmse4603(--nospam--at)gmail.com>:

So are they doing this to reduce drift or keep the depth of the truss down?


I'd say it's to reduce drift. It has a deeper (3'+-) section than you'd likely use with a conventional moment frame. That's what I've read about the Special Truss Moment Frames is that they are stiffer than a SMRF so I'd expect the same about an Ordinary Truss Frame. They're laid out same as if he was using typical moment frames; 2-stories, 3-bays, each side of the building. From what I've read and what we've discussed in-house, we're leaning towards allowing this.
