Seismic,
RISA-3D,
New
RISA-3D
has
two
ways
of
automatically
generating
seismic-related
Basic
Load
Categories
(BLCs)
which
can
be
later
referenced
in
the
Load
Combinations
(LCs):
1.
Creating
seismic
BLCs
(ELX,
ELZ,
etc)
from
the
Seismic
Load
Generator
2.
Creating
seismic
BLCs
(SX,
SZ,
etc)
from
Response
Spectra
Analysis
In
addition
to
the
automatic
generated
seismic
loads,
users
can
always
draw
any
loads
and
add
them
to
seismic
load
consideration.
How
to
generate
seismic
loads
from
the
seismic
load
generators
are
further
discussed
here:

Once
the
seismic-related
Basic
Load
Categories
(BLCs)
are
created,
they
can
be
used
in
analysis
by
referencing
them
in
the
Load
Combinations
(LCs).
RISA-3D
also
has
Load
Combination
(LC)
Generators
that
will
generator
seismic-related
combinations
based
on
selected
codes.
How
to
use
the
LC
generator
is
further
discussed

The
seismic
load
categories
(ELX,
ELZ,
etc.)
generated
from
the
Seismic
Load
Generator
can
also
be
viewed
visually
from
the
load
display.
The
seismic
load
categories
(SX,
SZ,
etc.)
generated
from
Response
Spectra
Analysis
cannot
be
viewed
visually,
but
users
can
check
the
total
base
reactions
from
the
joint
reaction
spreadsheet
as
a
reflection
for
the
applied
