DESCRIPTION:



Under certain circumstances, TYPE STRUCTURAL WALL design can "freeze"

GTSTRUDL during a PROPORTION command.  A non-terminating iteration is

entered and the user must halt (abort) the execution of GTSTRUDL and all

data is lost.



There is no work-around, but this problem is rare, with one reported

instance.

DESCRIPTION:

When performing an elastic buckling analysis (PERFORM BUCKLING ANALYSIS

command) with more than five active loadings, a value of 0.0 will be output

for the Buckling Multiplier for the loads beyond the first five active

loadings or an abort may occur.



Workaround:

Peform the buckling analysis for only five active loadings in each

execution.  Do not use the Load List command due to GPRF 93.25 still being

open.

DESCRIPTION:



     The scope environment OVERLAY DIAGRAM/ENVELOPE command may abort if

the active loading conditions contain no member loads.  A workaround is to

explicitly specify the number of sections using the SECTION command prior

to entering the scope environment and performing the OVERLAY operation.  An

example of the SECTION command is given as follows:



               SECTION FR DS 0.0 0.05   $ Produces 21 sections.
