This
...
test
...
problem
...
evaluates
...
...
response
...
when
...
the
...
yield
...
point
...
on
...
the
...
interaction
...
surface
...
changes.
...
Since
...
the
...
yield
...
point
...
is
...
defined
...
by
...
coordinates
...
which
...
couple
...
axial
...
and
...
bending
...
behaviors,
...
post-yield
...
changes
...
in
...
loading
...
conditions
...
will
...
also
...
cause
...
the
...
yield
...
point
...
to
...
change.
...
For
...
evaluation,
...
a
...
concentrated
...
hinge
...
is
...
assigned
...
to
...
the
...
fixed
...
end
...
of
...
a
...
cantilever
...
beam.
...
A
...
moment
...
and
...
axial-compressive
...
force
...
are
...
applied
...
to
...
the
...
free
...
end.
...
Hinge
...
response
...
is
...
then
...
reviewed
...
for
...
a
...
series
...
of
...
several
...
load
...
sequences
...
which

are

assigned

to

a

time-history
