RISAFloor,
Diaphragms,
New
RISAFloor
is
the
RISA
Building
System’s
floor
design
software
which
allows
users
to
design
with
composite
decks,
elevated
concrete
slabs
and
more.
When
paired
with
RISA-3D,
the
two
create
a
complete
solution
for
the
analysis
and
design
of
multi-story
structures,
including
two
buildings
on
the
same
podium.
Equivalent
Lateral
Force/Static
Force
Procedure
After
the
definition
of
slab
edges
and
the
application
of
diaphragms
in
RISAFloor,
RISA-3D
is
used
to
determine
the
different
lateral
forces
that
need
to
be
attributed
to
each
individual
diaphragm
that
exists
at
each
elevation.
These
story
forces
can
then
be
displayed
graphically
(as
shown
below)
per
diaphragm
at
each
elevation.
Dynamic
Analysis
If
your
building
requires
a
dynamic
analysis,
mode
shapes
can
be
calculated
and
displayed
in
the
same
fashion
as
they
are
for
a
single
structure.
Similarly,
building
frequencies
and
mass
participation’s
are
just
as
simple
to
retrieve
by
simply
choosing
“frequencies”
or
“mode
shapes”
from
the
Results
Toolbar
or
the
Results
menu
drop-down.
Intermixing
Diaphragm
Types
RISA
also
allows
users
to
analyze
with
different
diaphragm
types
(flexible,
semi-rigid,
rigid)
at
the
same
elevation
of
your
separate
buildings.
Using
RISAFloor
paired
with
RISA-3D,
engineers
can
analyze
and
design
complex
structures
with
this
configuration.
