How
...
is
...
a
...
MIVAN
...
system
...
modeled
...
in
...
ETABS?
...
Answer:
...
A
...
...
system
...
is
...
a
...
type
...
of
...
formwork
...
for
...
rapid
...
construction
...
of
...
multi-story
...
buildings.
...
The
...
structures
...
created
...
using
...
MIVAN
...
formwork
...
may
...
have
...
levels
...
without
...
beam
...
systems,
...
instead
...
being
...
composed
...
only
...
of
...
walls
...
and
...
slabs.
...
This
...
type
...
of
...
system
...
may
...
be
...
modeled
...
in
...
...
using
...
...
objects
...
for
...
walls
...
and
...
slabs.
...
Since
...
these
...
area
...
objects
...
entirely
...
resist
...
loading,
...
shells
...
should
...
be
...
adequately
...
...
to
...
capture
...
bending,
...
shearing,
...
torsional,
...
and
...
axial
...
behavior.
...
For
...
most
...
models
...
of
...
this
...
type,
...
...
analysis
...
will
...
be
...
necessary.
...
A
...
key
...
concern
...
when
...
modeling
...
MIVAN
...
systems
...
includes
...
locations
...
where
...
these
...
interconnecting
...
shells
...
transition
...
into
...
transfer
...
girders
...
and
...
supporting
...
columns,
...
which
...
are
...
necessary
...
for
...
levels
...
with
...
uninterrupted
...
areas,
...
such
...
as
...
parking
...
or
...
the
...
ground
...
floor.
...
To
...
achieve
...
proper
...
connectivity
...
to
...
the
...
walls
...
above,
...
it
...
may
...
be
...
effective
...
to
...
model
...
girders
...
and
...
columns
...
using
...
wall
...
objects.
...
Here,
...
wall
...
stresses
...
should
...
be
...
investigated
...
more
...
closely.
...
Principal
...
stresses
...
may
...
be
...
plotted
...
in
...
ETABS
...
to
...
indicate
...
load
...
path.
...
Arching
...
action
...
in
...
deep
...
girders
...
should
...
also
...
be
...
closely
...
observed.
