Precast wall element parameters

Tool(s): Modify Parameters, Basic Reinforcement

Select the check boxes of the parameters you want to modify and enter a new value. Only the parameters whose check boxes are selected are taken into account.

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.

General

Factory

Select a factory you have defined in the Factory catalog in the Catalogs.

Type (wall panels only)

You can convert concrete wall panel elements to sandwich wall panel elements and vice versa.

Outer/leaf thickness

You can modify the thickness of a facing concrete layer for concrete walls. The program takes into account this thickness in the production data (concrete distributor data). However, it is ignored for the purposes of weight calculation.

You can change the thickness of the two leaves for double walls. Any changes are always applied towards the interior; in other words, the thickness of the wall does not change – instead, the space between the two leaves changes.
When the program creates the elements based on the new leaf thickness, it checks the maximum element weight and issues a message, if necessary. Please note that the program neither updates connections automatically nor checks the positions of fixtures and additional reinforcement. In addition, you have to divide the walls again.

Concrete cover

Concrete cover of reinforcement.

Concrete grade

Select a concrete grade in the catalog.

Exposure class

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). Among other things, cement formulation, minimum concrete cover and minimum concrete strength grade depend on the exposure class.

Concrete grade of core layer (concrete wall only)

Select a concrete grade in the catalog.

Exposure class of core layer (concrete wall only)

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). Among other things, cement formulation, minimum concrete cover and minimum concrete strength grade depend on the exposure class.

Surface

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

Status

You can change the element states and actions determined by the program.

Additional text for mark number

Complementary text for mark number.

Additional attributes

Can only be selected when entries have been made in the configurations. Click the Name button to select an attribute or cancel its selection. The data entry box can be changed. The defaults are defined in the configurations.

The attributes can be analyzed as follows:

• As text under the mark number (with the Attr1 to Attr30 string variables for the custom attributes 1 to 30).
• As variables for label styles. Use the Additional custom attribute from the Precast concrete elements area and specify the number of the additional attribute you require using the Special index.
• As variables in the list generator of the BFT menu.

Element parameters, ... (wall panels only)

You can change the element parameters of the selected wall panel element. The fixtures created cannot be modified.

Reinforcement

Lattice girder type

Select a girder type in your catalog if you have selected the Manual option for 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.

Required bar cross-section / Reinforcement type

Depends on the reinforcement method selected. If you reinforce according to the as-value, changing this value only causes the reinforcement type to change. The program automatically determines the correct reinforcement type. If you reinforce (manually) using the reinforcement type catalog, you cannot change the as-value but you can change the reinforcement type.

Bar overlap top - bottom / sides

Reinforcement overlap top and/or bottom or side; you can make separate settings for the visible and invisible wall sides.
Use the Configurations to specify where the overlaps are created.

Bending shape top - bottom / sides

Bending shape top and/or bottom or side; you can make separate settings for the visible and invisible wall sides. Click to open a dialog box in which you can select the bending shape.
Use the Configurations to specify where the bending shapes are created.

Reinforcement direction

Span direction of wall reinforcement. The span direction of a wall (i.e., the direction of longitudinal bars or lattice girders) is set to 0 degrees. 90 degrees means that longitudinal bars and lattice girders are placed at right angles in the wall.
