Enter a Section under Name.

2

Import a material.

3

From any column of the added row, click on three-dots icon (blue star) to open Section Editor panel.

4

You can open the tab which includes Polygon, Template, Rebar and Tendon by clicking (blue star) icon at the left top side of the screen.

5

To define a polygon shape, click to at (blue star) Shapes tab, then click the coordinates of an arbitrary shape.

(blue star) Follow the below steps to utilize a Template.

1

Click (blue star) .

2

If you don’t have a 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

3

Edit dimensions of the shape to create the section. Click to Import.

4

After you import the section, it will show up on the analytical view.

Rebar Definition

(blue star) Follow the below steps to add rebars to your section.

1

Click (blue star) at the Shapes tab.

2

If you don’t have a Rebar definition in your project, you will get a popup to import one. Just click OK and continue.

3

Select your asset from OpenBrIM Database for rebar profile and click Import.

4

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.

9

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.

Tendon Definition

(blue star) Follow the below steps to add tendon to your section.

1

Click (blue star) at the Shapes tab.

2
Expand
titleQuick Tip

After you import the material for the tendon and add the tendon to your section, you can rearrange the coordinates of the tendon.

Also, you can use a parametric relationship as input for Y1=d/2-10 (d = depth of the section). The position of the rebar depends on the section depth.

Tip

Tendon definitions are completed. Remember this training example doesn’t require any tendon definition.

Section Editor Features

(blue star) Follow the below step to open the features tab of the section.

1

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.
