DESCRIPTION:

     The MEMBER DIMENSIONS command in Volume 4 (Reinforced Concrete) will
calculate incorrect values for IZ and SZ for CROSS shaped members with a
value given for H2 (See Figure 2.5 -1, Volume 4).  AX, AY, AZ, IX, IY and
SY are calculated correctly.  Other shapes (RECTANGLE, TEE, RL, LL and
CIRCLE) are not affected by this problem.

     There is no workaround, and IZ and SZ for CROSS shapes should be
calculated using another method, such as by hand, The new values may be
input into GTSTRUDL using CHANGES mode:

     CHANGES

      MEMBER PROPERTIES
          list1 IZ V1 SZ v2
          list2 IZ v1 SZ v2
     ADDITIONS

       where list is a list of CROSS shaped members,
          v1 is the new IZ value, and
          v2 is the new SZ value

To verify the change:

     PRINT MEMBER PROPERTIES MEMBERS list1 list2

command
