The Base tab manages the elementary model parameters.
Model
The 'Model name' must be specified, as it is also the file name of the model. The 'Model description', on the other hand, is optional. You can use it to briefly describe the model. The description appears in the printout report, but otherwise – like the description of the series – has no further function.
Series
Select the project folder in which the model is to be created from the 'Series name' list. You can create a new project using the
button. The 'Create New Project' dialog appears for entering the corresponding data.
The
button opens the Dlubal Center. There, you can set a different project as current (see chapter
Models
).
For information, the 'Description of series' and the 'Folder' of the selected project are displayed.
Analysis
Activate the check boxes of the design methods to be used for the calculation. The following methods are available:
- Thin-walled analysis
- Finite element analysis
One or both design methods can be selected simultaneously.
Activate the check box 'Plastic capacity design | Simplex method' to investigate the plastic cross-section capacity under consideration of the interaction of internal forces.
Activate the check box 'Effective section / Steel / Aluminum cross-section' to determine the effective section according to the relevant standards. One of the following standards can be selected:
- EN 1993-1-1 and EN 1993-1-5
- EN 1993-1-3 (Cold-formed)
- EN 1999-1-1 (Aluminum)
You can make further detailed settings in the Settings and Options tab.
Options
In this section, you define the basic settings for the calculation.
Definition of material
With this check box, you can control whether material input is required for the cross-section. This check box must be activated for the calculation of the effective cross-section or definition of the concrete reinforcement.
Manual input of single panels
To determine the effective section according to EN 1993-1-1 in connection with EN 1993-1-5, EN 1993-1-3 or EN 1999-1-1, the single panels of the cross-section are to be defined. These are usually derived automatically from the cross-section geometry. By activating the 'Enable manual input of single panels' option, the single panels can be adjusted by the user. Editing is carried out in the 'Single Panels' table of the 'Special Objects' or via the 'Edit Single Panel' and 'New Single Panel' dialogs.
US notation for cross-section properties
Activate the check box to display the symbols of cross-section properties according to US convention.
Concrete reinforcement
With this check box, you can control whether concrete reinforcement can be defined.
Composite cross-section
Activate this check box to define a composite cross-section where the connection of the individual parts can be specified via Connectors.
Stress smoothing to avoid singularities
Activate the check box to smooth stress peaks.
Comment
Here, you can enter a text to add a remark to the model. This comment also appears in the printout report.
