GPRF No.: 99.07

DESCRIPTION:

The COMPUTE FATIGUE commands of the offshore module will abort if any member designated in the FATIGUE MEMBER command is also designated as both a chord and a brace in the CHORDS FOR FATIGUE command. If this situation exists, the best work-around is to break the fatigue analysis into separate jobs, where the members that function as both braces and chords are treated as chords only in one job and braces only in another. In the following example, the series of FATIGUE MEMBER and CHORDS FOR FATIGUE commands designate member 11213 as a brace member for fatigue -analysis by the FATIGUE MEMBER DATA command, while the subsequent CHORDS FOR FATIGUE command designates this member as both a brace and a chord.

FATIGUE MEMBER DATA
     11213 PIPE EQUAL SCF VARIABLE EQUATIONS SMEDLEY T MINIMUM SCF 1.5
     11215 PIPE EQUAL SCF VARIABLE EQUATIONS KUANG Y MINIMUM SCF 1.5
     11410 PIPE EQUAL SCF VARIABLE EQUATIONS KUANG Y MINIMUM SCF 1.5

CHORDS FOR FATIGUE
CHORD 11213 JOINT 11115
     BRACE 11410 GEO 'Y'
     BRACE 11215 GEO 'Y'
CHORD 11033 JOINT 11015
     BRACE 11213 GEO 'T'
CHORD 11034 JOINT 11015
     BRACE 11213 GEO 'T'
CHORD 11211 JOINT 11115
     BRACE 11215 GEO 'Y'
     BRACE 11410 GEO 'Y'
END OF CHORD DATA

---

These commands can be broken apart in separate jobs so that member 11213 functions only as a brace for the fatigue analysis in one job and only as a chord for the fatigue analysis in another:

Rev. 2.2

1. First job -- member 11213 treated only as a chord

FATIGUE MEMBER DATA
     11215 PIPE EQUAL SCF VARIABLE EQUATIONS KUANG Y MINIMUM SCF 1.5
     11410 PIPE EQUAL SCF VARIABLE EQUATIONS KUANG Y MINIMUM SCF 1.5

CHORDS FOR FATIGUE
CHORD 11213 JOINT 11115
     BRACE 11410 GEO 'Y'
     BRACE 11215 GEO 'Y'
END OF CHORD DATA

2. Second job - member 11213 treated only as a brace

FATIGUE MEMBER DATA
     11213 PIPE EQUAL SCF VARIABLE EQUATIONS SMEDLEY T MINIMUM SCF 1.5

CHORDS FOR FATIGUE
CHORD 11033 JOINT 11015
     BRACE 11213 GEO 'T'
CHORD 11034 JOINT 11015
     BRACE 11213 GEO 'T'
END OF CHORD DATA
