Rebar
Figure 17.10–1 Rebar location in a beam section.
Data lines to define isoparametric rebar in three-dimensionalshell elements:
First line:
1. Elementnumber or name of the element set that contains these rebar.
2. Cross-sectionalarea of each rebar.
3. Spacing of the rebar in the plane of the shell. The default is 1.0.
4. Positionof the rebar in the shell secti ont hickness direction. This value is given as the distanc e
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 THICKNESS parameter is included with
the *SHELL SECTION option of the underlying shell element.
5. Edgenumber 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 ofrebar.
Data lines to define isoparametric rebar inthree-dimensional membrane elements:
First line:
1. Elementnumber or name of the element set that contains these rebar.
2. Cross-sectionalarea of each rebar.
3. Spacingof the rebar in the plane of the membrane. Thedefault is 1.0.
4. Edgenumber 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 ofrebar.
