Per
the
ACI,
you
can
add
a
Shear
Cap
to
your
column
to
increase
the
shear
strength
of
the
slab.
In
RISAFloor
ES
two-way
slabs,
adding
a
shear
cap
will
thicken
the
plates
around
the
column
automatically.
The
Shear
Cap
will
affect
the
Punching
Shear
and
the
One-Way
shear
calculations.
As
you
draw
the
columns
in
RISAFloorES,
there
is
an
option
to
include
a
Shear
Cap.
The
thickness
is
measured
from
below
the
bottom
of
the
slab.
The
Depth
and
Width
are
based
on
the
column
definition
and
local
axis.
It
is
common
to
model
without
Shear
Caps
and
only
add
Shear
Caps
as
they
are
needed.
You
can
add
Shear
Caps
to
the
columns
at
any
time
from
the
Windows
menu-
Modify
–
Columns.
This
allows
you
to
create
a
Shear
Cap
on
an
existing
model
and
shift
the
Shear
Cap
eccentrically.
You
can
also
modify
the
Shear
Cap
in
information
is
stored
in
the
Columns
spreadsheet.
The
eccentricity
is
defined
based
on
the
column
local
axis.
The
picture
below
shows
a
Shear
Cap
that
is
shifted
eccentrically
by
12
inches
in
the
ey
and
ez
directions.
