I'm confused as someone define cases just as follows.
these cases are for branch isolated from main pipe,
1 WW+HP HYD
2 W+D1+T1+P1 OPE design temp
3 W+D2+T2+P1 OPE ope temp
4 W+D3+T3+P1 OPE mini temp
5 W+P1 SUS
6 W+D2+T2+P1+WIN1 OPE
7 W+D2+T2+P1+WIN2 OPE
8 W+D2+T2+P1+U1 OPE
9 W+D2+T2+P1-U1 OPE
10 W+D2+T2+P1+U2 OPE
11 W+D2+T2+P1-U2 OPE
where D1，D2，D3 are displacements in main pipe of corresponding cases,(that is design,ope and mini temp), are these cases upward right?
should I add diplacement of sus case of main pipe to case 5?
just as following:
5 W+P1+D4 SUS (where D4 is displacement of sus case in main pipe)


another question: Is there any differece when the stress type of case 6 to 11 is OCC.
give me some advice, thanks!
