3.2 Materials

The window is divided into two parts. The upper section lists the concrete classes and steel grades relevant for the design. All materials of the 'concrete' category used for members in RFEM are preset. In the Material Properties section, the properties of the current material, that is the material whose table row is selected in the upper section, are shown.

Figure 3.17 Window 1.2 Materials

Column A lists the materials relevant for the design of the members. Materials that are not allowed are highlighted in red, modified materials in blue.

Chapter 4.3 of the RFEM manual describes the material properties used for the determination of the internal forces. The design-relevant material properties are also stored in the global material library. The values are preset for the Concrete Strength Class and for Reinforcing Steel.

To adjust the units and decimal places of the characteristic values and stresses, select Settings → Units and Decimal Places in the menu (see chapter 8.3).

Material description
Concrete Strength Class

The materials used in RFEM are already preset.

The strength class can be changed at any time: Click the material in column A to select the field. Then, click the button, or press the [F7] function key to open the list of strength classes. The list contains only strength classes in accordance with the design concept of the selected standard.

After importing a material, the Material Properties are updated in the section below.

The material properties are generally not editable in RF-CONCRETE Members.

Reinforcing Steel

In this column, the program presets a steel grade in accordance with the design concept of the selected standard.

As with the concrete strength class, you can select a different reinforcing steel from the list: Click the material in column B to select the field. Then, click the button or press the [F7] key to open the list of reinforcing steels. As with the concrete strength classes, the list contains only steel grades that are relevant for the selected standard.

After importing a material, the Material Properties are updated in the section below.

Material library

Many materials are stored in a database. To open the library, select the menu item

    • Edit → Import Material from Library

or use the button shown on the left. You can find the library buttons below columns A and B.

Figure 3.18 Material Library dialog box

In the Filter section, the materials relevant to the standard are already preset, thus excluding all other categories or standards. You can select the desired concrete strength class or steel grade from the Material to Select list; then you can check the properties in the section below.

Click [OK] or press Enter to import the selected material into window 1.2 of RF-CONCRETE Members.

Chapter 4.3 of the RFEM manual describes how to filter, add, or reorganize materials.
