PT beams warp or twist off posts?
No, I was not advocating the toe nailing method at all (I've always used Simpson BCS post caps and H1 hurricane connectors for the beam-to-joist connections in my decks).
As far as assembled beams twisting, I guess anything is possible, though I've seen more bowing beams (curving in one direction) in my old decks.
What type of soil is under your deck? Is it pitched to direct water away below? I read that if you have a clay-like soil on the surface, it can possibly cause frequent lateral ice heaving.
