2.1.3 DnV-RP-C201 Panel Code Check

Column 35 of the OPTIONS line can be used for selecting code checks for stiffened or un-stiffened panels. Enter “A” for API BULL 2V or “D” for DnV-RP-C201. Currently only DnV-RP-C201 code of practice is implemented.
The DnV-RP-C201 plate panel code could be used in accordance to either the LRFD or WSD standards by specifying the appropriate code check options in column 25-26 of OPTIONS line.

Plate panels will be checked in accordance to WSD standard if the following options are selected in columns 25-26 of the OPTIONS line,
“UC” – For WSD AISC 9th / API RP 2A 21st edition;

“4A” – For WSD AISC 14th / API RP 2A 21st edition.

“AA” – For WSD AISC 13th / API RP 2A 21st edition.


Plate panels will be checked in accordance to LRFD standard if the following options are selected in columns 25-26 of the OPTIONS line:
“4L” – For LRFD AISC 14th / API RP 2A – LRFD 1st edition;
“AL” – For LRFD AISC 13th / API RP 2A – LRFD 1st edition;
“LR” – For LRFD AISC 1st edition / API RP 2A – LRFD 1st edition;
“L2” – For LRFD AISC 2nd edition / API RP 2A – LRFD 1st edition;
“L3” – For LRFD AISC 3rd edition / API RP 2A – LRFD 1st edition;
“EC” – For Eurocode 3 (LRFD) with NORSOK 2004 N-004;
“NS” – For NORSOK 2004 N-004 (LRFD) with NS3472;
“DC” – For 1994 Danish Code (LRFD)
“D1” – For 1984 Danish Code (LRFD)
“BS” – For 1990 BS5950 Code (LRFD)
“CA” – For 1994/2001 Canadian (LRFD) Code Check

The PCODE input line for DnV-RP-C201 code of practice may be used to input user defined parameters. Currently all the options in this line are only applicable to DnV-RP-C201 code of practice.  The PSTIF input line can be used designate a stiffener to be checked as a plate girder in addition to the torsional and column buckling lengths and also the stiffener yield stress value.
The PGRUP line can be used to define particular plate groups belonging to a panel by entering 'P' in column 6.
Note: All plates forming a panel should have the same unique plate group label.
