Hello,
I have a water hammer calculation (time history) for 48" GRE line according to ISO 14692. I consider the load case combination as follow: static/dynamic combination:
LOADE CASE FACTOR
D1 1
S3(W+T1+P1)(OPE)) 1

THE STRESS RESULT: NO CODE STRESS CHECKED.

Your help will be highly appreciate.
Thank in advance,
Moussa
