Constant section (PRE-Stress)
If Constant section is enabled when defining the element in the Project manager:
Then the Section database will give the user the possibility to use predefined sections or define custom sections.
Standard Eurocode concrete
This database consists of predefined sections, some for example-purposes, others are cross sections from manufacturers.
Non-standard concrete
The Non-standard database is a user-defined database. It will save and contain all the user defined cross sections created by the user.
By selecting the Non-standard concrete database on the left and one of the supported cross sections on the right it is possible to see the stored cross section, and the program will give an option to [Add] new sections.
Entering values in the measurements input fields, a name for the cross section and then pressing [Add] will calculate the cross sectional parameters.
And by then pressing [OK] it will be stored in the database.
A few more options for the cross section is now available:
[Change] will give the user the option to change the cross section
[Delete] will remove it from the database.
Manage cross sections
There is a special feature for the user-defined cross sections. By right-clicking on the name and selecting "Manage cross sections..." / "Hantera tvärsnitt..." it is possible to add a note, warning or disable a cross section. This can be good if an old cross section has been used in older files, but it should be kept in the list, even if a newer version is available.
There are three advanced settings:
- Show information (information icon + message)
- Show warning (warning icon + message)
- Block the usage of this section
The message is shown above the preview.
For blocked sections the [OK]-button is disabled, making it impossible to add the cross section to the project.

| hw2 | mm | Height of the topmost inclined part of the flange |
F-Section
The F-section (Flange-beam) is defined by the following parameters:
| Parameter | Unit | Description |
|---|---|---|
| H | mm | Height of the element |
| B | mm | Width of the flange (element) |
| d | mm | Width of the web |
| t | mm | Height of the flange |
This section is symmetric so both flanges will have the same height
Fh-section
The Fh-section (Half flange beam) is defined by the following parameters:
| Parameter | Unit | Description |
|---|---|---|
| H | mm | Height of the element |
| B | mm | Width of the flange (element) |
| d | mm | Width of the web |
| t | mm | Height of the flange |
KB-section
The KB-section is defined by the following parameters:
| Parameter | Unit | Description |
|---|---|---|
| H | mm | Height of the element |
| B | mm | Width of the bottom of the element |
| t1 | mm | Height of the left flange |
| t2 | mm | Height of the right flange |
| c1 | mm | Width of the left flange |
| c2 | mm | Width of the right flange |
| k1 | - | Ratio of te slope of the left flange |
| k2 | - | Ratio of te slope of the right flange |
KBE-section
The KBE-section is defined by the following parameters:
| Parameter | Unit | Description |
|---|---|---|
| H | mm | Height of the element |
| d | mm | Width of the web |
| B | mm | Width of the bottom of the element |
| t | mm | Height of the flange |
| k | - | Ratio of te slope of the flange |
D-section
The D-section is a special slab-like element defined by the following parameters:
| Parameter | Unit | Description |
|---|---|---|
| H | mm | Height of the element |
| B | mm | 1.0m width of the total element. (Locked) |
This section can't be designed with stirrups, use Rectangular solid section for those purposes.
Hollowcore / HD-section
One way to define a hollowcore is by enterring parameters, the other is by importing a dwg/dxf-file. The Hollowcore-section is defined by the following parameters:
| Parameter | Unit | Description |
|---|---|---|
| B | mm | Width of the bottommost part of the element |
| b | mm | Width of the bottommost part of the element |
| H | mm | Height of the element |
| h | mm | Height of the cores |
| n | - | Number of cores |
| s | mm | Spacing between the cores |
| c | mm | Distance between the top of the core to the top of the element |
| bt | mm | Width of the top of the cores |
| bb | mm | Width of the bottom of the cores |
| rt | mm | Radius of the top of the cores |
| zrt | mm | Distance from the top to the centerpoint of the radius for the top of the cores |
| rb | mm | Radius of the bottom of the cores |
| zrb | mm | Distance from the bottom to the centerpoint of the radius for the bottom of the cores |

| nb | - | Number of divisions of the curvature of the bottom of the cores |
| nt | - | Number of divisions of the curvature of the top of the cores |
Note: In orderr to have different sizes of the cores the dwg/dxf-import needs to be used since the parameter-input only can handle one size of the cores.
