Re: Evaluation of salvaged Steel Joists

An undamaged, unmodified, properly bridged 18H8 is capable of safely
supporting a uniform load that causes a moment of 540 in-k, and an end
shear of 5400#.  So depending on your spacing 100 psf is no problem.
You make me nervous with your mention of being cut with a torch.  Even
slight modifications can significantly affect the strength.  Be careful,
and remember your own statement that the SJI is "guessing".
