This part is to inform about the general purposes of section definitions. Follow the next steps to create different section definitions that OpenBrIM provides.
Section Editor
Follow the below steps to use Section Editor. | ||
|---|---|---|
| 1 | Enter a Section under Name. |  
|
| 2 | Import a material. | |
| 3 | From any column of the added row, click on three-dots icon to open Section Editor panel. |
|
| 4 | You can open the tab which includes Polygon, Template, Rebar and Tendon by clicking icon at the left top side of the screen. |
|
| 5 | To define a polygon shape, click to at Shapes tab, then click the coordinates of an arbitrary shape. | |
| 6 | You can rechange the locations by clicking ‘Points Spreadsheet’ after you assign the shape.
| |
Follow the below steps to utilize a Template. | ||
|---|---|---|
| 1 | Click . |
|
| 2 | If you don’t have a material already imported (or defined as custom), you can import by clicking . 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
Follow the below steps to add rebars to your section. | ||
|---|---|---|
| 1 | Click 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 , 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 . 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 . |
|
| 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 |
|
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
Follow the below steps to add tendon to your section. | ||
|---|---|---|
| 1 | Click at the Shapes tab. |
|
| 2 | 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.
| |
Tendon definitions are completed. Remember this training example doesn’t require any tendon definition.
Section Editor Features
Follow the below step to open the features tab of the section. | ||
|---|---|---|
| 1 | By clicking 3 dot button, you can open the features tab of the section. |
|
Examine the below definitons to understand the section editor features. | |||
|---|---|---|---|
| 1 | Rename Section | Allows to change the name of this section. | |
| 2 | Print Report | Allows to change page size. | |
| 3 | Materials | See the materials assigned in this section, rebar and tendon. | |
| 4 | Rebar Profiles | See the rebar profiles. | |
| 5 | Section Properties | Section properties of the section such as area, inertia, plastic section modulus, etc. |
|
| 6 | Flexure Capacity | Computes flexural capacity of the section. Before moving on with this feature, make sure that you have all the related stress-strain models in the material definitions. |
|
| 7 | Moment Curvature | Computes the moment-curvature diagram of the section. |
|
| 8 | Interaction Diagram | Computes Axial Force-Moment Interaction diagram. |
|
| 9 | Set C.O.G. as Origin | Changes the origin of the section to (0,0) point. | |
Example Custom Section with Custom Material
Mechanical properties of the section like Area and Inertia are also customizable with two options:
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.
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.
