In the table Materials of the 'Steel Design' category, all materials created in your model are listed.
Permissible Materials
Steel design is bound to materials of the Steel type. The font color of the materials indicates the use and admissibility of the material. The colors mean:
- black: Material is suitable for design and is used for the objects to be designed
- red: Material is not suitable for steel design
- blue: Material is not used in the model
- gray: Material is not used for the objects to be designed
Objects assigned an invalid material are not taken into account in the design – even if the 'To be designed' option is activated for this material. They are automatically shown in the Objects to be designed table as 'Invalid / disabled'.
Remove Material from Design
For a valid material, you can exclude all objects assigned to the material from the design by deactivating the 'To be designed' check box. These objects are then classified in the Objects to be designed table as 'Invalid / disabled' and are not checked in the design.
Adjust Material Properties for Design
If you want to use custom strengths or partial safety factors for steel design, you can adjust the material properties: Double-click the corresponding table row or use the
button in the table toolbar to open the material editing dialog.
In the 'Base' tab, select the User-defined material option (see chapter Materials of the RFEM manual). This allows you to edit the material properties. For example, in the 'Material Values' tab you can change the stiffnesses of the material and the strengths in the individual thickness ranges.
In the 'Steel Design' tab, you can adjust the material's partial safety factors for design according to the selected Standard, for example γM0 and γM1 for EN 1993.
Options
The symbols in the 'Options' column stand for various settings or modified values. They provide a quick overview, for example to identify materials with adjusted properties.
