RISAFloor,
New,
Steel Joists,
Joists
As
a
floor-by-floor
design
software,
RISAFloor
includes
robust
features
for
the
design
of
steel
joists,
including
standard
joists,
long-span
joists
and
composite
joists.
Version
16
of
RISAFloor
now
includes
design
according
to
the
latest
specification
(SJI
45th
Edition)
as
well
as
expanded
LH-series
design
tables.
The
new
45th
Edition
Catalog
provides
a
more
practical
approach
to
better
define
the
actual
use
of
the
products
in
the
catalog.
All
of
these
changes
below
are
aimed
at
making
steel
joists
and
Joist
Girders
safer,
simpler
to
use
and
more
economical.
The
LH-Series
Load
Tables
have
been
expanded
to
incorporate
shorter
spans
with
higher
uniform
design
loads
as
well
as
additional
standard
designations,
particularly
for
floor
systems.
Because
of
these
expanded
LH-Series
Load
Tables,
the
Safe
Load
as
well
as
the
LH
Load/Load
weight
tables
are
no
longer
needed
and
have
been
removed.
LH-Series
Load
Tables
layout
has
been
reformatted
to
match
the
K-Series
Load
Tables.
Tables
outlining
bearing
conditions
and
bridging
information
have
been
updated
to
include
the
new
LH-Series
chord
numbers.
The
Duct
Opening
Accessories
page
has
been
updated.
Added
page
describing
additional
joist
minimum
shear
criteria
for
web
design.
