Give this a try first...
The temperature field can accept other data than temperature. If you type in a number that is less than 0.5 (by default), CAESAR II will interpret the data as strain (inches/inch or mm/mm) rather than temperature.
I believe, currently, your CAESAR II model will show a strain of 0.001414 for the operating temperature. If you replace those temperatures (121C or 250F) with 0.001348 you should be able to match the Appendix S values.
I just updated the strains. The previous values (0.001224 & 0.001168, respectively) were based on an ambient temperature of 70F and this model has an ambient temperature of 40F.
