DESCRIPTION:

                              STEEL DESIGN



          The MAXIMUM AXIAL FORCES option of the SELECT command may abort

     for a member with an axial force exactly equal to 0.0 for all active

     load conditions.



          The MAXIMUM AXIAL FORCES option of the CHECK command for a

     member with an axial force exactly equal to 0.0 for all active load

     conditions may result in the following warning message.  The code

     check will not be performed.



**** WARNING_STTPLC --   RESULTS NOT AVAILABLE FOR MEMBER 9 LOADING

                         CODE CHECK NOT PERFORMED FOR THIS LOADING.



     Note that the loading name is missing in the above warning message.



          The MAXIMUM AXIAL FORCES option of the SELECT or CHECK command

     is applicable to the transmission tower codes (TOWER, and TOWER2

     only.



          Example:

               PARAMETERS

                    'CODE'    'TOWER2'   ALL

          LOAD LIST 1 TO 10

          SELECT MEMBERS 5 MAXIMUM AXIAL FORCE DESIGN ONLY

     or

          CHECK MEMBERS 9 MAXIMUM AXIAL FORCE CHECK ONLY



          The maximum axial force for members 5 and 9 for the loads 1 to

          10 is equal to 0.0.



     Workaround:

          Do not use the MAXIMUM AXIAL FORCE option of the SELECT or

          CHECK command for the members which have 0.0 axial force for

          all active load conditions.

                                              DATE: January 11, 1996

DESCRIPTION:



     The LIST MAXIMUM STRESS command will produce incorrect results for

     the maximum or minimum normal stress under the following conditions:

     1.   The cross section of the member was specified using TABLE

          properties and the cross section is supported by the POSITION

          option of the LIST SECTION STRESS command.

     2.   The sign of the normal stress is the same (either all positive

          or all negative) for all sections along the member, for all

          loadings, and for all positions that are applicable to the

          member's cross section using the POSITION option of the LIST

          SECTION STRESS command.

     If the above conditions are true and the normal stress is always

     positive, a zero (0.0) will be output for the minimum normal stress

     instead of a positive number which is less that the maximum normal

     stress.

     If the above conditions are true and the normal stress is always

     negative, a zero (0.0) will be output for the maximum normal stress

     instead of a negative number which is less in magnitude than the

     minimum normal stress.



     Under most conditions this error should not govern a design since

     for the case of the normal stress always being positive, a correct

     value for the maximum normal stress will be output.  Likewise, for

     the case of the normal stress always being negative, a correct value

     for the minimum normal stress which is larger in magnitude will be

     output.



     Workaround:

     Do not use TABLE properties to specify the MEMBER PROPERTIES of the

     cross section.  Print out the properties using the PRINT MEMBER

     PROPERTIES command and then specify the properties using MEMBER

     PROPERTIES PRISMATIC.

                                              DATE: January 11, 1996

DESCRIPTION:



     The LIST MAXIMUM STRESS command will output the incorrect loading

     name for the loading which produces the minimum normal stress if the

     first active loading causes the normal stress in the member.  The

     value of the minimum normal stress will be correct except as noted

     in a previous GPRF No. 96.04.



     Workaround:



     The only known workaround is to change the order in which the

     loadings are created so the minimum normal stress is not caused by

     the first active loading when the LIST MAXIMUM STRESS command is

     given.  For most models, this is not practical.
