Dear all,

I am analyzing a piping system connected to an equipment with large amount of settlement. Would you pls clarify that the following load cases considering the fact that settlement causes secondary stress are valid?

L1/W+P SUS (STRESS CHECK)
L2/W+P+T+D OPE
L3/L2-L1 EXP (STRESS CHECK)

THANK YOU
