Has anyone had this problem before?
I'm using CAESAR II 2014, 7.00.01.1600, (Build 141003).
I first built a model with 1 temperature and 1 pressure and then ran the model with the default load cases.
L1: W+T1+P1 OPE
L2: W+P1 SUS
L3: L1-L2 EXP
The system passed, but I noticed some supports were lifting off. I went back to the model, and without changing anything else, I went to the Load Case Editor. I added two cases to account for the Hot Sustained case and now my load cases look like this:
L1: W+T1+P1 OPE
L2: W+P1 SUS
L3: T1 OPE
L4: L1-L2 EXP
L5: L1-L3 SUS
For some reason, the EXP case (L4 now) is now failing. The calculated stresses are about 30% higher than before. What would cause this stress to change?
As far as I can see, nothing in cases 1, 2 or 4 should have changed from the first run, correct?
Any help is appreciated.
