By clicking (blue star) , you can switch the layout of the rebar as Line, or Circular.

5

Let’s stay on Line Layout, and enter rebar layout input data

6

After you click Add, you should click the start and end location points of the section. No need to be exact in locations,they can be edited later.

7

After clicking end location, Edit Linear Rebar Layout window appears.

8

Edit Linear Rebar Layout.

If you don’t have a rebar material already imported (or defined as custom), you can import by clicking (blue star) . If you have, just select it from the Material drop-down.

10

After Apply all the entered data in Edit Linear/Circular Rebar Layout window, you can change the location of the rebar layout at the analytical coordinate system by clicking Points Spreadsheet under (blue star) .

11

Applying the same procedure, you can insert rebars at top and bottom. This time number of rows is set to 1 and rebar layouts placed twice for top and bottom, respectively

Tip

The rebars are completed. This training example doesn’t require any tendon definition; the below steps explain how to add a tendon layout to the section.

Example Custom Section with Custom Material

...

Mechanical properties of the section like Area and Inertia are also customizable with two options:

  1. Section with shape definition: It requires defining section shape via Section Editor or importing from the section database. In that case, section-related properties are automatically calculated.

  2. Section without shape definition: It requires entering section property parameters manually. The Has Geometry (read-only) parameter turns into NO by default in that option.
