Hi,

On the exemple at the bottom (CAESAR 7.00.01.1600 Build 141003)
I perform the following load cases:
L1 WW+HP+H HYD
L2 W+T1+P1+H OPE
L3 W+T2+P1+H OPE
L4 W+T3+P1+H OPE
L5 W+T4+P1+H OPE
L6 W+T5+P1+H OPE
L7 W+P1+H SUS
L8 L2-L7 EXP
L9 L3-L7 EXP
L10 L4-L7 EXP
L11 L5-L1 L7 EXP
L12 L6-L7 EXP
L13 L8,L9,L10,L11,L12 EXP

Options:
L2-L7(EXP) Keep Disp/Force/Stress Algebraic
L3-L7(EXP) Keep Disp/Force/Stress Algebraic
L4-L7(EXP) Keep Disp/Force/Stress Algebraic
L5-L7(EXP) Keep Disp/Force/Stress Algebraic
L6-L7(EXP) Keep Disp/Force/Stress Algebraic
L8,L9,L10,L11,L12(EXP) Keep Disp/Force/Stress Max

The allowable of the MAX of EXP cases (L13) is equal to 1.5Sh instead of 1.25SC+0.25Sh as for the others cases (L8 to L12).
Did I miss something or is there a issue?
