                                        GPRF No.: 96.10



                                        DATE: 12 March, 1996



DESCRIPTION:



Multiple support acceleration TRANSLATION description lines in the

RESPONSE SPECTRUM LOADING command will cause a specified acceleration

response spectrum file to be treated as a displacement response spectrum

file when the loading data are stored.  This will produce incorrect

response spectrum analysis results which may not be obvious.



An example of the problematic RESPONSE SPECTRUM LOADING command input

follows:



          RESPONSE SPECTRUM LOAD 1

          SUPPORT ACCELERATION

            TRANSLATION X 1.0 FILE 'EX-XZ'

            TRANSLATION Z 1.0 FILE 'EX-XZ'

          END



Section 2.4.4.6.2 implies that only one TRANSLATION command line is

allowed and if multiple global directions are desired, then the following

form of the TRANSLATION command shall be used:



          RESPONSE SPECTRUM LOAD 1

          SUPPORT ACCELERATION

            TRANSLATION X 1.0 Z 1.0 FILE 'EX-XZ'

            END



An example of output which illustrates this problem also follows:

DESCRIPTION:



     Use of the USER VARIABLE SCF option of the FATIGUE MEMBER DATA

command causes incorrect fatigue stresses and incorrect fatigue lives to

be computed.  There is no known work-around to this problem.  An example

of this problematic form of the FATIGUE MEMBER DATA command follows:

          FATIGUE MEMBER DATA PIPE EQUAL 45.0 -

            SCF VARIABLE USER START SADDLE AX 6.0 IPB, 1.5 OPB 4.0 -
