In
RISA-3D,
moving
load
results
are
generated
by
simulating
a
load
that
moves
across
a
structure
in
defined
increments.
These
loads
are
often
used
for
designing
bridges,
cranes,
or
other
structures
where
dynamic
loads
shift
across
the
structure
over
time.
Moving
loads
are
complex
because
they
involve
numerous
load
steps,
each
with
its
own
set
of
internal
forces
and
deflections.
Due
to
the
large
number
of
iterations,
RISA-3D
envelopes
moving
load
results,
meaning
only
the
maximum
and
minimum
values
for
each
member
or
section
are
shown.
This
helps
simplify
the
output
and
avoids
an
overwhelming
volume
of
data.
However,
to
view
individual
load
steps
for
detailed
analysis,
a
different
approach
must
be
used.
Viewing
and
Creating
Moving
Load
Steps
in
Load
Combinations
To
review
moving
load
results
such
as
deflections
and
force
diagrams
step
by
step
in
RISA-3D,
you
need
to
generate
load
combinations
that
reflect
individual
moving
load
steps.
Here’s
how
you
can
view
and
create
these
steps:
Identify
the
Desired
Moving
Load
Step:
First,
you
must
determine
which
moving
load
step
you
want
to
investigate
in
detail.
This
can
be
done
by
reviewing
the
envelope
results
and
noting
the
governing
load
combination
and
step
number
in
the
"LC"…
