Cross-Section Library

Many cross-sections are stored in a database.

Opening the library

The library can be accessed in the 'Name' dialog section using the Library button (see image New Section ).

The library is divided into sections, including various cross-section types. Find the category of the relevant cross-section and click the button with the corresponding symbol.

Standardized cross-sections

For cross-sections of the "Standardized" category, another dialog box opens where you can select the cross-section.

You can do the following for selecting a cross-section:

  • Reduce the selection using the suitable criteria in the "Filter" section on the left.
  • Use the full text search in the "Search" field at the bottom.

If you want to select a different cross-section type, you can return to the overview with the Back button.

Filter

The Filter section offers various selection options. You can filter the cross-sections using certain criteria, thus reducing the selection (see the image Selecting Rectangular Hollow Section).

Tip

Use the Filter button at the bottom of the section to control whether cross-sections of standards that are no longer valid are also displayed.

Section Series to Select

In the middle section, you define the cross-section series in which the material is filed. The series are sorted by standard, manufacturer, region, and manufacturing type. You can control the sorting order by clicking the column headings.

Use the Section Information button at the bottom of the section to check the properties of the selected cross-section.

Section to Select

In the right section, you can select the Section to be used in the model.

Click OK or use the Enter key to transfer the selected cross-section to the "New Section" dialog box.

Built-up cross-sections

In this dialog section, it is possible to combine standardized cross-sections by parameter control. You return to the "New Section" dialog box, which now shows an additional tab.

In the "Combination Types" section, you define how the cross-sections are arranged (1). Then, in the "Sections" dialog section, you can select the relevant cross-sections in the library one by one by using the Library button (2) (3).

Thin-walled and massive cross-sections

When you select a thin-walled or massive cross-section type in the library, you can define its geometry parameters in the "New Section" dialog box. An additional tab is available for the definition.

Tip

For thin-walled cross-sections, you can preset the dimensions of a certain rolled section with the Presetting Rolled Section button.

Favorite sections

It is possible to save frequently used cross-sections as Main Favorites. They are then available as preferred cross-sections ("favorites") in other projects.

To save the current cross-section as a favorite, click the New Favorite button at the bottom of the library after defining the section or the definition parameters. This way, the cross-section is stored in the "My Sections | Main" category.

Use the Edit button to check your preferred cross-sections. The cross-sections saved as favorites are listed and sorted by section types in the "Edit Favorite List" dialog box.

Use the New button to create a new category in the list of preferred cross-sections.

To import a preferred cross-section from the library, click the Favorite button in the '"From Favorite List" dialog section.

RSECTION cross-sections

You can also import user-defined cross-sections in RSTAB that you have created in the RSECTION program. Click the Select Section from RSECTION  button in the "From RSECTION" section. A note to "Select section in Dlubal Center" appears; the Dlubal Center opens. In Dlubal Center, select the RSECTION cross-section.

In order to import the cross-section, certain license conditions must be met. In the RSECTION cross-section, information is stored about the licenses that were available in RSECTION when the cross-section was saved. The following rules apply:

  • You do not need to save the RSECTION cross-section, including results, to use it in RSTAB.
  • If an RSECTION license user creates a cross-section and saves it in RSECTION, other users can import this cross-section in RFEM, run structural analyses, and design it in a design add-on like Steel Design or Aluminum Design even if they don't have a license for RSECTION.
  • RSECTION cross-sections whose design in the Steel Design or Aluminum Design add-ons requires the consideration of the effective cross-section must also be saved in RSECTION with an active license for Effective Sections.
