You said:
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".
