Dear Raja,

Hope this will help you. Assume we only has simple load W, P, T, D, Wind and using CODE ASME B 31.3.

L1 WW+HP (HYD)
L2 W+P+T+D (OPE)
L3 W+P+T+D+Win1 (OPE)
L4 W+P+T+D+Win2 (OPE)
L5 W+P+T+D+Win3 (OPE)
L6 W+P+T+D+Win4 (OPE)
--------------------------
L7 W+P (SUS)
L8 T+D (EXP); just created to generate HOT SUS
L9 L2-L7 (EXP)*
L10 L2-L8 (HOT SUS)*
--------------------------
L11 L2-L3 (OCC)*
L12 L2-L4 (OCC)*
L13 L2-L5 (OCC)*
L14 L2-L6 (OCC)*
L15 L11+L12+L13+L14 (OCC)****
----------------------------
L16 L7+L15 (OCC)***; combined of SUS+Max wind to have OCC

Note:
* Use algebraic combination method under the Load Case Options tab.
** Use SRSS combination method under the Load Case Options tab.
*** Use ABS or Scalar combination method under the Load Case Options tab.
**** Use Maximum combination method under the Load Case Options tab.

Now, you can see we set up L3, L4, L5, and L6
L3 W+P+T+D+Win1 (OPE)
L4 W+P+T+D+Win2 (OPE)
L5 W+P+T+D+Win3 (OPE)
L6 W+P+T+D+Win4 (OPE)

to have L11, L12, L13, and L14:
L11 L2-L3 (OCC)*
L12 L2-L4 (OCC)*
L13 L2-L5 (OCC)*
L14 L2-L6 (OCC)*

in order to have the maximum efect of 4 direction of wind to piping system using ***max combination methode in L15:
L15 L11+L12+L13+L14 (OCC)****
Why? wind assume will not come in 4 direction in the same time. We just take the bad effect from which direction (corretc me if i'm wrong).

In my opinion, the combination you mentioned for SUS are not correct:
W+P1+Win1+H
W+P1+Win2+H
W+P1+Win3+H
W+P1+Win4+H

why? SUS will not include WIN which are occasional.
