"The higher SL, the lower your Sa value"
"Yes, that is correct. However, the EXPansion allowable will then be computed as: Sa = f(1.25Sc + 0.25Sh). This equation always produces a lower allowable than the one sited above (unless of course Sl > Sh, which means your SUStained case failed)".

Mr,Richard you said that CAESAR II is use the higher SL value so the Sa value will be lower in expansion case, so why CAESAR II use the Sa= f(1.25Sc + 0.25Sh) - SL as a default ?? Isn't it will be a higher value of Sa compare to Sa= f(1.25Sc + 0.25Sh) when liberal stress value check is off ?? please correct me if i'm wrong.
