REBAR
4. Orientation of rebar in degrees. See Figure 17.10–3.
5. Fractional distance from the edge given below, f (ratio of the distance between the edge and
the rebar to the distance across the elem ent).
6. Edge number from which the rebar are defined. See Figure 17.10–4 or Figure 17.10–7.
7. Isoparametric direction (for three-dimensional elements only).
8. For axisymmetric elements only, the radial position at which the spacing of the rebar is
measured. If this entry is nonzero, the rebar spacing is assumed to vary linearly with radial
position. If this entry is zero or blank, the rebar spacing does not vary with position.
Repeat this data line as often as necessar y. Each line defines a layer of rebar.
Data lines to define a layer of uniformly spaced rebar in continuum elements (SINGLE parameter
omitted) when the layer is parallel to only one isoparametric direction in the element’s local
(isoparametric) coordinate system (GEOMETRY=SKEW):
First line:
1. Element num ber or name of the element set that contains these rebar.
2. Cross-sectional area of each rebar.
3. Spacing of rebar. The default is 1.0.
4. Orientation of rebar in degrees. See Figure 17.10–3.
5. For axisymmetric elements only, give the radial position at which the spacing of the rebar is
measured. If this entry is nonzero, the rebar spacing is assumed to vary linearly with radial
position. If this entry is zero or blank, the rebar spacing does not vary with position.
6. Isoparametric direction (for three-dimensional elements only).
Second line:
1. Fractional distance along e dge 1, (see Figure 17.1 0–5).
2. Fractional distance along edge 2,
.
3. Fractional distance along edge 3,
.
4. Fractional distance along edge 4,
.
Only the two values corresponding to the two edges that the rebar intersects can be nonzero.
Repeat the first and second data lines as often as necessary. Each pair of lines defines a layer of rebar.
Data lines to define a single rebar in continuum elements (SINGLE parameter included):
First line:
1. Element number or nam e of the element set that contains the rebar.
2. Cross-sectional area of the rebar.
3. Fractional distance,
, locating the rebar’s position in the element (se e Figure 17.10–6).
4. Fractional distance,
, locating the rebar’s position in the element.
