I assume your case 5. should have been L2-L1.


Yes you're correct - typo on my part.


Regarding your suggested load cases above:
  • Cases 5, 6, and 8 are your code stress compliance cases
  • Case 4 is not a stress case. This case should only be used for restraint loads, restraint design, and max deflection checks.
  • Case 9 is not a valid combination. You are combining the effects of the occasional load (wind) with the expansion stress range. You don't want to add stresses to a "stress range".
