RISA-3D,
Results,
New,
Wall Panels
In
the
Node
Reaction
spreadsheet,
all
reactions
from
node-based
boundary
conditions
are
reported.
If
you
look
closely
at
some
models,
there
may
be
wall
panel
labels
in
the
Node
Reactions
spreadsheet
as
well.
This
may
cause
users
to
ask
the
question:”what
are
these
reaction
values
for
a
2-dimensional
wall
panel”?
The
answer
is
that
the
Wall
Panel
Reactions
represent
the
total
reactions
(resultant)
for
the
wall
about
located
at
the
center
of
the
wall.
This
location
does
not
change
even
if
the
center
of
the
wall
is
within
an
opening,
or
if
the
edge
of
the
wall
is
restrained
as
well
as
the
base.
The
reason
why
the
program
is
reporting
this
for
the
wall
is
to
provide
the
user
an
overall
idea
of
the
loading
condition
on
each
wall
panel;
such
as
total
axial,
shear,
and
overturning
moment.
In
most
cases,
the
reaction
values
at
this
location
is
representative
of
the
overall
loading
condition.
You
may
also
notice
that
these
reactions
are
calculated
using
force
equilibrium
at
the
bottom
center
of
the
wall,
and
are
not
directly
derived
from
the
finite
element
analysis
(FEA).
In
the
actual
analysis,
depending
on
the
boundary
conditions
the
user
assigned
at
the
wall…
