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
...
...

Name: Hinge response when yield point changes
Description: Behavior of a concentrated plastic hinge when the loading applied to a nonlinear frame object causes the yield point of the interaction surface to change position.
