'Design' configuration entry

Configuration Double Wall: Design

Initial values for wall element design.

'Parameters' tab

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

Panel thickness visible, invisible:

[m] Leaf thickness for double walls; initial values for the default prompt.

Shortening BL visible, invisible:

[m] Initial values for shortening the leaves as far as the architectural wall.

Concrete grade visible, invisible:

Default concrete grades for the design. The list box provides all entries that are defined in the concrete grade catalog and assigned to the current factory.

Exposure class visible / invisible:

Default for the exposure class.
Cement formulation, minimum concrete cover, and minimum concrete strength grade depend on the exposure class.

Surface visible, invisible:

Enter the text describing the concrete surface finish that is used as an initial value.

Additional text for mark numbers:

Additional text for mark number.

'Formwork attributes' tab

Visible leaf / Invisible leaf:

No chamfer / Chamfer / Special formwork

You can define the default formwork attributes for the different panel edges. You can make separate settings for the visible and invisible sides. When designing, you can select more attributes in the Design Type dialog box; you can combine all attributes freely.

'Special formwork' tab

Special formwork for wall chases:

This option is relevant to the Unitechnik CAD-CAM interface.
You can specify whether special formwork is to be applied to panel edges of wall chases when the chase value specified cannot be met.

'Marks' tab

Assignment of marks:

Specify the mark numbers the program assigns to precast elements while creating them. When you modify elements later, they get the mark numbers specified here. This also applies if you have rearranged the elements manually in the meantime by using the Modify Mark Number tool.

Zero: The elements initially get the mark number zero and will be rearranged manually later.

Ascending: The elements get numbers in ascending order.

Identical: While creating elements, the program automatically checks the elements based on the following criteria:

• Identical geometry (volume, outline, recesses, ...)
• Identical element attributes (material, …)
• Identical number and position of fixtures and identical fixture attributes and variables
• Identical reinforcement (position of reinforcement in precast element, parameters, bar parameters such as bending pin diameter, hook lengths, …) and reinforcement attributes (for example, steel grade)
  

'Weight calculation' tab

Calculate weight based on:

Define the option you want to use to calculate the weight of the precast element.

Option 1: The volume of the precast element will be multiplied by the value defined for Specific weight of reinforced concrete in the concrete grade catalog.

Option 2: The net concrete volume of the precast element will be multiplied by the value defined for Specific weight of concrete in the concrete grade catalog. Then the steel weight will be added to the result.
To calculate the net volume of concrete, the program subtracts the steel volume (calculated from steel weight, specific weight of steel (78.5 kN/m3)) from the volume of the precast element. When calculating the steel volume, the reinforcement in in-situ concrete layers is not recognized. Lattice girders are considered at the percentage specified below.

Option 3: The volume of the precast element will be multiplied by the value defined for Specific weight of concrete in the concrete grade catalog. Then the steel weight will be added to the result.

Note: The net volume of concrete is available as an attribute for label styles, reports and so on.
Note that reinforcement is not yet known at the time of design or division. Therefore, the weight cannot be calculated based on options 2 and 3 (division by maximum weight or consideration of crane). The preview of the label also displays the weight in accordance with option 1.
When you use options 2 and 3, the program updates the weight constantly to reflect changes you make to the outline or reinforcement of the precast element.

Consideration of lattice girders:

Specify the percentage up to which the program is to consider lattice girders when calculating the net volume of concrete.

Consider stirrup cages and bent-up meshes:

Specify the percentage up to which the program is to consider stirrup cages and bent-up meshes when calculating the net volume of concrete.
Note: The bars are recognized as stirrup cages or bent-up meshes, which are defined using the Stirrup cages and Bent-up meshes functions in Secondary reinforcement, where the stirrups, longitudinal are not considered as a percentage, Bar shapein Secondary bars of any shape in Secondary reinforcement as well as Bar shape in the Bar reinforcement task area.
