21' code has 2x SYP and 2x and 4x Hemlock beams and joists. Why no 4x SYP beams? Sure, it IS NOT the same as a double 2x... but it still exists. I'm surprised the code has 4x hemlock but not 4x SYP when SYP is super common for PT and thus could be used as a 4x6 joist or 4x6 beam (I know out west hemlock is common).
I have two current situations that would benefit from prescriptive engineering for 4x SYP beams/joists.
