12.8.11 Defining rebar layers

When you create homogeneous shell sections, composite shell sections, membrane sections, or surface sections, you can define one or more layers of reinforcement (rebar) by using the Rebar Layers option. You access the Rebar Layers dialog box from the section editor.

To define rebar layers:

  1. From the Options field of the shell, membrane, or surface section editor, click Rebar Layers.

    The Rebar Layers dialog box appears.

  2. Choose either Constant or Angular rebar spacing. Angular rebar spacing is valid only for rebar in axisymmetric models.

  3. In the table, enter a row of data for each rebar layer.

    Each row should contain the following information:

    • The name of the rebar layer.

    • The name of the material forming the rebar layer. Click in the Material column, then click the arrow that appears to display the list of available materials, and select the material forming the rebar layer.

    • The cross-sectional area per bar.

    • The rebar spacing in the plane of the section. For angular rebar spacing, specify the spacing angle in degrees.

    • The angular orientation of the rebar (in degrees) relative to the 1-direction of the rebar reference orientation or an orientation name. If you specify an orientation name, ABAQUS/CAE assumes a user-defined orientation. You must supply the user subroutine ORIENT that contains the definition of the user-defined orientation for the specified orientation name. For more information, see ORIENT, Section 25.2.14 of the ABAQUS Analysis User's Manual.

    • The position of the rebar in the shell thickness direction measured from the middle surface of the shell, positive in the direction of the positive normal to the shell (not applicable for membrane sections or surface sections).

  4. Click OK to return to the section editor.
