Base

The Main tab manages the basic model parameters.

Dialog Box "New Model - Base Data", Tab "Main"
01 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', however, is optional. It allows you to describe the model briefly. The description appears in the printout report, but has no other function, such as the description of the series.

02 Model Description in Printout Report

Series

In the 'Name of Series' list, select the project folder where you want to create the model. Use the New Project you can create a new project. The 'Create New Project' dialog box appears where you enter relevant project data.

Dialog Box "Create New Project"
04 Dialog Box "Create New Project"

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

The 'Description of the series' and the 'Folder' of the selected project are displayed for information.

Analysis

In the list, select the design method that you want to use for the calculation. The following analysis methods are available:

  • Thin-Walled Analysis
  • Finite element analysis

You can also change the design method subsequently.

Select the 'Plastic capacity design | check box Simplex Method' to analyze the plastic cross-section resistance taking into account the interaction of internal forces.

Info

In the plastic resistance design, shear stresses are varied over the cross-sectional area in addition to the normal stresses variation. The plastic redistribution of shear stresses is only possible if elements are also defined. If no elements are defined, it is assumed for the shear stress internal forces that they are determined from the entered internal forces Vu, Vv, Mxp, and Mxs after the elastic calculation before the plastic calculation is initiated with the Revised simplex algorithm.

Add-ons

RSECTION can determine the effective section according to the following standards:

  • EN 1993-1-1 and EN 1993-1-5
  • EN 1993-1-3 (Cold Formed)
  • EN 1999-1-1 (Aluminum)

In the Settings & Options tab, you can specify further detailed settings.

The calculation of the effective cross-section requires a license for the 'Effective Section' extension. The green dot in front of the extension shows that a license is available. If the extension is marked with an orange dot, it is only available in demo mode.

Options

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

US notation for section properties

Activate the check box to display the symbols of section properties according to the US convention.

Concrete reinforcement

Use this check box to control whether a concrete reinforcement can be defined.

Info

A reinforced concrete design is only possible in the Concrete Design add-on.

Stress smoothing to avoid singularities

Select the check box to smooth stress peaks.

Comment

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