Rebar
Figure 17.10–1 Rebar location in a beam section.
Data lines to define isoparametric rebar in three-dimensional shell elements:
First line:
1. Element number or name of the element set that contains these rebar.
2. Cross-sectional area of each rebar.
3. Spacing of the rebar in the plane of the shell. The default is 1.0.
4. Position of the rebar in the shell section thickness dir ection. This value is given as the distance
of the rebar from the middle surface of the shell, positive in the direction of the positive normal
to the shell. This value is modified if the NODAL THICKN ESS param eter is included with
the
*
SHELL SECTION option of the underlying shell element.
5. Edge number to which the rebar are parallel in the element’s local (isoparametric) coordinate
system. See Figure 17.10–2.
Repeat this data line as often as necessary. Each line defines a layer of rebar.
Data lines to define isoparametric rebar in three-dimensional membrane elements:
First line:
1. Element number or name of the element set that contains these rebar.
2. Cross-sectional area of each rebar.
3. Spacing of the rebar in the plane of the membrane. The default is 1.0.
4. Edge number to which the rebar are parallel in the element’s local (isoparametric) coordinate
system. See Figure 17.10–2.
Repeat this data line as often as necessary. Each line defines a layer of rebar.
