In the Concrete Cover tab, you can control the concrete cover of the reinforcement used for the surface design.
Option
The check box is deactivated by default so that the concrete cover is determined using the exposure class, in accordance with the standard. If you select it, the concrete cover can be user-defined.
Concrete Durability
In most cases, the concrete cover is controlled by the concrete durability assigned to the surface. The program determines the concrete cover directly using this specification. If you have already defined the types of Concrete Durability, you can select the proper type from the list.
Use the button to create a new (or further) type. The button allows you to edit the concrete durability type selected in the list. You can use the button to graphically adopt the type from another surface.
Concrete Cover acc. to Standard
Here, you can specify the minimum concrete cover cnom that, according to the Standard , must be observed for the selected exposure class. This value cannot be changed.
User-Defined Concrete Cover
This section is only displayed if you have selected the User-Defined check box in the Option section. You can specify the concrete cover manually here (see the image Defining Concrete Cover). The value c is the distance of the external rebars from the top or bottom surface side.
