Thanks for the ping. Let me look at this for a while.
Two corrections, one a mistake in labelling, another a mistake in identification of east truss members, neither of which affect the conclusions drawn in the discussion.
One, a typo in Image 4, the member designated “Top Chord Tension Member U8-L7” should instead be labelled “Top Chord Tension Member U8-U7.”
Two, in images 3 and 4, the member labelled “Southeast Pier 6 Kingpost” is probably, on deeper reflection, the U8-L9 Tension Diagonal. Visual inspection indicates this is a flanged H-beam member, not a built up box beam as the kingpost would be.
The kingpost is minimally visible in Image 4, very close in location to the member mis-identified as the kingpost, but very difficult to see as it rests directly behind the U8-L7 tension diagonal when viewed from this angle.
In Image 4, the visible sliver of the SE kingpost is seen immediately below the terms “sway brace” in “U8 Floor Truss Top Chord or Sway Brace Horizontal (?)”.
The lower sections of the SE kingpost identified in Images 6 and 7 are labelled correctly.
Sorry for any confusion this may have caused.
