RISA-3D,
RISAFloor,
New,
Steel,
AISC
Engineers
choose
RISA-3D
and
RISAFloor
for
the
design
of
all
types
of
steel
structures.
As
a
result,
we
are
constantly
improving
the
software
and
its
acceptance
of
various
types
of
design
elements
and
materials.
The
latest
improvement
includes
back-to-back
hot
rolled
steel
channels
which
are
now
available
in
both
RISA-3D
Version
20
and
RISAFloor
Version
16.
These
member
types
are
becoming
more
popular
in
industrial
and
warehouse
structures.
These
new
shapes
are
now
available
for
design
utilizing
the
following
American
and
Canadian
codes:
AISC
360-16
(15th
Edition)
AISC
360-10
(14th
Edition)
CSA
S16-14
The
label
of
each
shape
uses
the
following
nomenclature:
2C(depth)
x
(weight)
x
(space)
The
last
value,
which
represents
the
space
between
the
channels,
is
in
an
eighths
of
an
inch
for
the
AISC
database
and
in
millimeters
for
the
Canadian
database.
For
instance
an
AISC
shape
2C15x33.9x6
would
be
two
back
to
back
C15x33.9
shapes
with
a
space
of
3/4"
(6/8)
between
them.
The
analysis
and
design
of
back
to
back
channels
are
very
similar
to
single
channels
however
the
program
will
take
into
consideration
how
the
channels
are
connected
to
each
other.
You
can
specify
whether
the
channels
are
connected
using
a
bolted
or
welded…
