Main


The Base tab manages the fundamental model parameters.

Dialog Box "New Model – Base Data", Tab "Main"
Dialog Box "New Model – Base Data", Tab "Main"

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. This allows you to briefly describe the model. The description appears in the printout report, but otherwise has no further function – just like the row description.

Row

Select the project folder in the 'Row name' list in which the model is to be created. With the New Project button, you can create a new project. The 'Create New Project' dialog appears for entering the corresponding data.

The Dlubal Center button opens the Dlubal Center. There, you can set a different project as the current one (see chapter Models ).

For information purposes, the 'Row description' and the 'Folder' of the selected project are displayed.

Analysis

Activate the check boxes of the analysis methods to be used for the calculation. The following methods are available:

  • Thin-Walled Structure Analysis
  • Finite Element Analysis

One or both analysis methods can be selected at the same time.

Activate the 'Plastic Capacity Design | Simplex Method' check box to investigate the plastic cross-section capacity considering the interaction of internal forces.

Info

For plastic capacity design, in addition to the variation of normal stresses, the shear stresses are varied simultaneously over the cross-section area. Plastic redistribution of the shear stresses is only possible if elements are also defined. If no elements are defined, it is simplistically assumed for the shear force internal forces that they are determined from the entered internal forces Vu, Vv, Mxp, and Mxs according to an elastic calculation before the plastic calculation is initiated with the Revised Simplex algorithm.


Activate the 'Effective Cross-Section / Steel / Aluminium Cross-Section' check box to determine the effective cross-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 (Aluminium)

In the Settings and Options tab, you can make further detailed settings.

Options

In this section, you define the basic settings for the calculation.

Material Definition

This check box allows you to 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 the definition of concrete reinforcement.

US Notation for Cross-Section Values

Activate the check box to display the symbols of cross-section values according to the US convention.

Concrete Reinforcement

This check box allows you to control whether concrete reinforcement can be defined.

Info

Reinforced concrete design is only possible in the Reinforced Concrete Design Add-On.

Stress Smoothing to Avoid Singularities

Activate the check box to smooth stress peaks.

Comment

Here you can enter text to add a remark to the model. This comment also appears in the printout report.
