Sections for Concrete Design

The Sections table of the "Concrete Design" category lists all cross-sections that have been defined for the model.

Allowable Cross-Sections

The font color of the cross-sections gives you the information about the utilization and validity of the cross-section for the concrete design:

  • Black = cross-section suitable for design
  • Red = cross-section not suitable for design
  • Blue = cross-section not used in the model
  • Gray = cross-section not used for objects to design

Info

Only certain cross-sections of the Massive I category are allowed for the concrete design. These cross-sections require the Concrete material type to be assigned to them.

In the current state of the program development, not all massive section types can be designed: You can create the reinforcement in the form of positions that are adapted to the cross-section geometry. The reinforcement layout for less common cross-sections is still in progress. Therefore, they are displayed in red in the table.

Info

In the RSECTION program, the concrete design of any cross-section is possible. You can also use these cross-sections for the design in an RFEM or RSTAB model (see the video on the right).

Removing Cross-Section from Design

For a valid cross-section, you can exclude from design all objects with this cross-section assigned by deactivating the "To Design" check box. These objects are classified as "Not Valid / Deactivated" in the Objects to Design table and not analyzed during the design.

Replacing Cross-Section for Design

If you want to use a different cross-section for the design than the one in the model, you can specify the name of the alternative cross-section in the "Use Other Section for Design" column. This does not affect the results of the structural analysis: The calculated member internal forces are used for the design of the alternative cross-section.

If there is a different cross-section entered in this column, further options are available in the shortcut menu of this cell. For example, you can export the modified cross-section to the main program in order to recalculate the internal forces with the modified stiffness.

Options

The symbols in the "Options" column are used for different settings or modified values. They allow for a quick overview, for example, to identify the cross-section with adjusted properties.

By clicking the icon, you can open the editing dialog box of the cross-section.

Warping Stiffness Deactivated  Indicates that the warping stiffness of the cross-section is not taken into account
Creep and Shrinkage Indicates that the Advanced Time-Dependent Properties of Concrete is activated
Info

The time-dependent properties of concrete (creep and shrinkage strain) can be defined globally for the material and adjusted for each cross-section with this material assigned.
