Wall element design, basic parameters

You can define design parameters in this dialog box. You can define default settings in the configurations for double walls, concrete walls, brick walls and wall panels.
When modifying the design, you cannot change the Type, Country/standard and Calculation parameters . You can modify the Factory parameter only for brick walls and wall panels.

Each wall has a viewing direction, which is defined by the position of the triangle symbol. Due to the viewing direction, there is a visible and an invisible wall surface.

Symbols for wall type and visible side of a wall

The following symbols are used to mark the individual wall types. Deleting the symbol automatically deletes the entire design.

or Double wall
or Concrete wall
Brick wall
Wall panel
Sandwich wall
Thermal wall without in-situ concrete
Thermal wall with in-situ concrete
n-layer wall

The side where the symbol is displayed indicates the visible side.
For concrete walls, this is the top (rough) surface in production (filling side).
For double walls, this is normally leaf 2, which is produced after leaf 1 and into which the predefined leaf 1 (plus the girders) is flipped.
For wall panels, it is the side that directly rests on the table in production.
For thermal walls, this is leaf 1 for production. The lattice girders or fixtures used to connect the leaves are assigned to this side and the insulation is always applied to it.

A concrete wall consists of two sides: a bottom side (smooth), which is directly on top of the formwork and invisible in production, and a coarse top side (this is the side where concrete is poured). This means that the bottom side is always associated with the invisible side.

A double wall consists of two leaves: a visible leaf and an invisible leaf. The visible leaf is indicated by the triangle symbol.
The invisible leaf is usually the ”girder leaf”; in other words, the leaf to which the lattice girders are assigned. As this leaf has to be produced first, it is often referred to as leaf 1.

Text for the surface finish. You can make this setting for the visible and invisible wall sides. However, it is only taken into account for the upper side in production (visible side) of a concrete wall. For single panels the text is printed next to the concrete grade.

Enter the appropriate exposure class.
You need to include the exposure class in reinforcement drawings according to DIN 1045-1, section 4.2.1 (3). Cement formulation, minimum concrete cover and minimum concrete strength grade depend on the exposure class.

Thickness of a facing concrete layer for concrete walls. The program includes this thickness in the production data (concrete distributor data). However, it is ignored for the purposes of weight calculation.

Thickness of the two leaves. The visible setting normally applies to leaf 2; the invisible setting to leaf 1.

Shortening at the top or bottom of the precast wall. When you enter a value, the program shortens the leaf opposite the architectural wall at the top or bottom.
The visible setting normally applies to leaf 2; the invisible setting to leaf 1.

Select a concrete grade from the catalog and enter the appropriate exposure class for the core layer.
You need to include the exposure class in reinforcement drawings according to DIN 1045-1, section 4.2.1 (3). For example, cement formulation, minimum concrete cover and minimum concrete strength grade etc. depend on the exposition class.

Select a girder type in your catalog if you have selected the manual girder calculation in the reinforcement parameters.
This way, you can create double walls without girders and use girders as spacers for basic reinforcement of concrete walls.

Note: There is no algorithm for calculating the lattice girders of concrete walls. You need to select a lattice girder using the Girder type parameter in the Precast walls dialog box.

Specify whether the wall element is to be produced automatically or transferred to special production. Select the type of special production.

You can select this button only if you defined entries on the configuration menu beforehand. Click the Name button to select an attribute or cancel its selection You can change the data entry box by defining defaults on the configuration menu.

You can see the data (name, manufacturer's address) of the factories listed in the Factory catalog on the Catalog Menu. You can define a new factory in the external catalog program or delete factories at any time.

You can see the standards entered in the Standards catalog on the Catalog Menu. You can set the default using the

Catalog, Factory and Standards Admin tool in the Catalogs and Configurations module.
This setting has an effect on the selection of concrete grades and steel grades. It applies to all precast elements in the current drawing file.

Note: You cannot change the Country/standard entry when you modify wall elements.

Using the Material definition dialog box, you can assign different material definitions (here, bricks) to brick walls of different thicknesses.

Using the Element parameters dialog box, you can define parameters for the four wall panel subtypes: concrete wall panel, sandwich wall panel, base element and facing element.

To save modified parameters

Enter a name for the favorite file.

To retrieve design parameters you have already saved

Click , specify the path and select the relevant favorite file.
Modify the parameters as you need.

To protect user-defined input parameters from unwanted or unauthorized alteration, any changes you make to the configuration are not automatically updated. You can use Restore basic settings to replace the existing parameters with the default parameters specified in the configuration.

Note: The default parameters are also used when you create a new factory.
