One further tidbit. After reading the suggested load case method for expansion ranges, I noticed that the preferred method according to the Caesar manual, as well as moderators here to do, as for in this case, L1-L2 (Algebraic)..so for my Caesar model above, I added this load case for LOAD CASE 8 = L1-L2. It turns out, my original LOAD CASE 7 = L5+L6 gives numbers much more closely resembling the results from Example 1 out of Appendix S of 31.3, Table S301.7, than this new LOAD CASE 8 = L1-L2.

So, what is the correct method to use? It appears that adding expansion cases (abs) like in my LOAD CASE 7 is more in line with ASME 31.3 no? I have attached my new Caesar model.
