*REBAR
Optional parameters:
GEOMETRY
This parameter is not meaningful for rebar in beams, axisymmetric shells, or axisymmetric
membranes, or for single rebar in continuum e lements.
Set GEOMETRY=ISOPARAMETRIC(default) to indicate that the layer of rebar is parallelto
a direction of the element local (isoparametric) coordinate system.
Set GEOMETRY=SKEWto indicate that the rebar layer is in a skew direction with respect to
the element faces.
ISODIRECTION
Set this parameter equal to the isoparametric direction from which the rebar angleoutput will be
measured. The default is 1.
ORIENTATION
This parameter is meaningful only for skew rebar in shell and membrane elements. Set this
parameter equal to the name of an orientation definition that defines the angular orienta tion of
the rebar. This parameter is not permitted with axisymmetric shell and axisymmetric m embrane
elements.
SINGLE
This parameter is meaningful only for continuum elem ents. Include this parameter if a single rebar
isbeing defined by each data line. Ifthis parameter is omitted, each line defines a layer of uniformly
spaced rebar in the element isoparametric space.
Data lines to define rebar in beam elements:
First line:
1. Elementnumber or name of the element set that contains these rebar.
2. Cross-sectionalarea of the rebar.
3. Distance (see Figure 17.10–1).
4. Distance .
Repeat this data line as often as necessary. Each line defines a single rebar.
