Loads,
RISAFloor,
New
RISAFloor
v11
allows
users
to
add
parapets
while
allowing
the
program
to
calculate
the
wind
loads
per
the
ASCE
7
parapet
wind
loading
requirements.
How
to
add
a
parapet
to
your
model?
The
Floors
spreadsheet
has
a
parapet
height
per
floor
which
is
the
default
for
the
entire
floor
level.
You
can
then
go
into
the
Columns
and
Wall
Panels
spreadsheets
to
customize
the
height
of
your
parapets
around
the
edges
of
your
roof.
For
columns,
the
program
will
go
around
the
edge
of
your
roof
and
find
the
column
parapet
height
at
each
location.
The
smaller
of
the
two
values
between
the
two
columns
is
the
parapet
height.
Once
this
is
complete
you
can
solve
your
model
and
use
the
Director
to
go
to
RISA-3D,
where
you
view
the
Wind
Load
Generation
dialog.
From
here
you
can
see
the
defined
geometry
and
the
wind
load
at
each
parapet.
This
load
is
then
lumped
in
with
the
regular
roof
wind
load
to
give
a
total
wind
force
in
each
direction…
