DYNAMCI LOAD CASE COMBINATION GRE PIPE ACCORDING ISO 14692 - 06/27/18 12:26 AM

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

Those piping codes that require more than one stress check for a load case (for example, offshore codes that evaluate hoop stress and maximum shearing stress or fiberglass codes that evaluate both hoop and axial stress) will not produce a Code-based stress for static and dynamic stress combinations.
