RISA-3D,
New,
Steel
In
RISA-3D
when
drawing
members
you
must
start
with
initial
sizes.
After
loading
and
load
combinations
are
completed
the
model
is
solved
and
then
member
design
must
be
done,
making
sure
that
members
pass
for
both
strength
and
serviceability
considerations.
For
both
strength
and
serviceability
considerations,
RISA-3D
has
the
ability
to
provide
Suggested
Design
results
to
help
optimize
member
design.
To
access
the
suggested
design,
first
make
sure
that
results
are
available
and
then
click
on
the
Suggested
Design
button
found
on
the
Results
tab.
These
suggested
shapes
are
either
based
on
Section
Sets
if
used,
or
on
individual
members.
For
Section
Sets
the
program
will
find
the
worst
case
member
code
check
within
each
Section
Set.
Based
on
that
member
the
program
will
provide
a
suggestion
of
a
shape
that
will
work
that
is
either
bigger
or
smaller
depending
on
whether
the
code
check
is
failing
or
passing
by
a
large
margin.
For
individual
members,
the
suggestion
is
made
based
just
on
that
member.
If
a
member
or
Section
Set
does
not
show
up
in
the
list
that
tells
you
that
either
the
current
section
is
optimal
or
a
section
cannot
be
found
to
meet
strength
criteria.
If
you…
