Dear Sir
I have some doubts regarding seismic load cases build in Caesar.

Please have a look at following combination method.In one of our projects these load cases are being used. I want to confirm their correctness.
L3 W+P2+T2
L6 W+P1
L19 W+T2+P2+U1
L20 W+T2+P2-U1
L21 W+T2+P2+U2
L22 W+T2+P2-U2
L23 W+T2+P2+U3
L24 W+T2+P2-U3
L25 L19-L3 (+U1)
L26 L20-L3 (-U1)
L27 L21-L3 (+U2)
L28 L22-L3 (-U2)
L29 L23-L3 (+U3)
L30 L24-L3 (-U3)
L31 L25+L27 (+U1+U2) (X ACCLN combined with vert. acceln.)
L32 L25+L28 (+U1-U2) (X ACCLN combined with vert. acceln.)
L33 L26+L27 (-U1+U2) (X ACCLN combined with vert. acceln.)
L34 L26+L28 (-U1-U2) (X ACCLN combined with vert. acceln.)
L35 L29+L27 (+U3+U2) (Z ACCLN combined with vert. acceln.)
L36 L29+L28 (+U3-U2) (Z ACCLN combined with vert. acceln.)
L37 L30+L27 (-U3+U2) (Z ACCLN combined with vert. acceln.)
L38 L30+L28 (-U3-U2) (Z ACCLN combined with vert. acceln.)
NOTE L31 TO L38 are SRSS
L44 L7+L31
L45
L7+L32
L46 L6+L33 (ABS) SUS+SRSS ACCELN
L47 L6+L34 (ABS) SUS+SRSS ACCELN
L48 L6+L35 (ABS) SUS+SRSS ACCELN
L49 L6+L36 (ABS) SUS+SRSS ACCELN
L50 L6+L37 (ABS) SUS+SRSS ACCELN
L51 L6+L38 (ABS) SUS+SRSS ACCELN
Please note that I have taken here only seismic related cases and other cases like hydro, expansion are not considered here.
My queries here are
1)are these load cases and combination methods are correct?

2)Here x dir(Hor) acceleration is combined with Y directional acceln and z dir (HOR) acceleration is also combined with vertical acceleration by SRSS combination method.
DO WE NEED TO BUILD A CASE WHERE X, Y Z DIRECTIONAL ARE COMBINED TOGETHER FOR STRESS AS WELL AS LOADS CHECK?

If yes, can anyone guide me please how to build these cases and their combination methods?

Best Regards,
