The
latest
releases
of
RISAFloor
and
RISA-3D
include
the
following
updates
to
wood
design
per
the
Canadian
codes:
Wood
Wall
Design
RISA-3D
v16
and
RISAFloor
v12
now
offer
design
of
wood
walls
per
the
Canadian
wood
design
codes
(CSA
O86-09
and
CSA
O86-14).
The
design
methodology
is
very
much
like
the
Segmented
method
used
by
the
NDS
design
codes.
Design
requires
chords
on
each
side
of
each
full
height
panel.
Design
assumes
that
the
areas
above
and
below
openings
have
zero
stiffness.
Only
full
height
piers
are
considered
to
resist
loading.
Additionally,
the
design
of
individual
panel
elements
is
as
follows:
The
sheathing
panel
is
assumed
to
resist
the
in
plane
shear
The
chords
are
assumed
to
resist
the
overturning
moment
The
studs
are
assumed
to
resist
the
axial
load
The
hold
downs
are
designed
for
the
governing
tension
chord
force
at
the
base
elevation
of
the
wall
Deflections,
including
the
effects
if
hold-down
elongation,
are
calculated
per
the
code
based
equation
