RISA-3D,
v18,
New,
Instability,
P-Delta
In
this
video,
you’ll
learn
how
to
investigate
your
RISA-3D
model
for
P-Delta
divergence
errors.
This
type
of
error
is
common
in
general
structural
analysis
software
and
has
two
major
causes:
a
model
that
is
unstable
or
a
model
that
is
too
flexible.
For
this
investigation,
two
separate
steel
frame
models
will
be
used
to
evaluate
a
workflow
to
solve
P-Delta
issues…
