Main

The Main tab manages the basic model parameters.

Model

It is necessary to specify the "Model name", as it is also the file name of the model. However, the "Model description" is optional. It allows you to briefly describe the model. The description appears in the printout report, but has no other function, such as the description of the series.

Series

In the "Series name" list, select the project folder where you want to create the model. You can also use the New Project button to create a new project. The "Create New Project" dialog box appears where you enter relevant project data.

The Dlubal Center button to open the Dlubal Center. There, you can set a different project than the current one (see Chapter Modelle ).

The "Series description" 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 | Simplex method" check box to analyze the plastic cross-section resistance, taking into account the interaction of internal forces.

Info

In the plastic capacity design, shear stresses are varied over the cross-sectional area in addition to the variation of normal stresses. 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 design before initiating the plastic design with the Revised Simplex algorithm.

Add-ons

RSECTION can determine the effective cross-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 of 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.

Material definition

Mit diesem Kontrollfeld können Sie steuern, ob für den Querschnitt eine Materialeingabe erforderlich ist. Für die Berechnung des effektiven Querschnitts oder Definition der Betonbewehrung muss dieses Kontrollfeld aktiviert sein.

US Notation for Section Properties

Activate this check box to display the symbols of the cross-section properties in compliance with the US convention.

Concrete Reinforcement

Use this check box to control whether to define concrete reinforcement.

Info

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

Stress Smoothing to Avoid Singularities

Select the check box to smooth the stress peaks.

Comment

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