Diameter catalog for precast concrete elements

Catalogs for precast concrete elements

Each entry in the catalog must also be available as a reinforcing bar in the Bar cross-section catalog ( Default Settings --> Defaults -> cross-section catalogs).

"General" tab

Created on:

Date the record was created.

Last modified:

Date the record was last changed.

Name:

User-defined name for the diameter.

ID number:

Some control systems require this reference number. You can enter any number; however, it must be unique.

Material number:

The external list generator can analyze material numbers as article numbers (for commercial interfaces).

Delivery time:

Delivery time in days. Some control systems require this for stock control.

Job lot:

Packaging unit size. Some control systems require this for stock control.

Manufacturer's data:

Full name of manufacturer. Some control systems require this for stock control.

"Miscellaneous" tab

Diameter:

Diameter in [mm].

Tolerance:

Dimensional tolerance for the diameters. Some control systems analyze this value.

as-value:

Bar cross-sectional area in [cm²]. You can configure the program to automatically calculate the cross-sectional area from the diameter. To do this, click the calculator symbol at the bottom. (The symbol is not available if the current record has not changed).

Weight:

Bar weight in [kg/m]. You can configure the program to automatically calculate the weight from the diameter. To do this, click the calculator symbol at the bottom. (The symbol is not available if the current record has not changed).

Use:

None/All bars/Longitudinal bars/Cross bars
Defines how to use the diameter.

For example, when you select Nothing or Cross bars, you cannot use this diameter for longitudinal bars during design.

"Welding1" tab

Use as 0°/90° bar:

If these check boxes are selected, you can enter the relevant parameters on this tab and on the Welding2 and Welding3 tabs.

0° bars:

min. axis spacing [mm]:
max. axis spacing [mm]:

The axis spacing between the 0º bars must always be an integer multiple of the grid spacing (= 50 mm) and must be 50 mm ≤ axis spacing a0º ≤ 1500 mm.

90° bars:

min. axis spacing [mm]:
max. axis spacing [mm]:

The grid spacing does not apply to 90° bars.
The limits for bars with a diameter of 6 and 8 mm must be 50 mm ≤ axis spacing ≤ 2000 mm.
The limits for bars with a diameter of 12 mm must be 60 mm ≤ axis spacing ≤ 2000 mm.

Bar can be welded with diameter:

Enter the diameters; use semicolons to separate the values. To identify a diameter, use its name.

"Welding2" tab

0°/90° bars:

If the Can be used as a bent bar check box is selected for the relevant type, you can enter parameters for this type on this tab and on the Welding3 and Welding5 tabs.

Bending pin: You can take the bending pin diameter from Allplan or use a machine-dependent value. If you have selected the second option, specify the diameter-dependent Bending pin diameters. If you enter several diameters, use semicolons to separate the values. You can use a dot or a comma for the decimal separator.
When creating the MWS mesh, the program uses the machine-dependent bending pin diameters to calculate the locked zones, bar positions, and so on.

Note: You can enter several values for machine-dependent bending pin diameters. This is very useful for MWS meshes with different diameters, enabling the machine to bend the mesh without having to change the bending pin. In this case, the number of starting points and end points entered in the From:/To: boxes of the locked zones on the Welding5 tab must be exactly the same as the number of start and end points in the Bending pin diameter box. In addition, you must adjust a setting in the configurations for Attached Reinforcement - Bending shapes. On the General 1 tab, select Diameter-dependent (catalog) for the Definition of locked zones.
When it comes to bending different diameters within a mesh, the program always uses the first common bending pin diameter. If it cannot find a common bending pin diameter, it displays a message and then uses the first value defined in the catalog. If there are more than two different diameters, parts of the mesh can be bent together.

Minimum axis offset for bent bars: Specifies the minimum value defined by the bending machine. This value is required to bend a single bar.

Minimum axis offset required on one side only: Uses the minimum distance between bent bars of one direction for one side.
After having selected this option, you can use the list box to specify the side.

Minimum segment length for bend: Compares the external dimensions of the bent bar segments with this value. When the segment length is too small, the mesh cannot be produced.

Maximum angle for bend: Specifies the maximum bending angle defined by the bending machine.

Maximum total bending length of segment: Compares the sum of the external dimensions of the bent bar segments with this value. When the segment length is too great, the mesh cannot be produced.

"Welding3" tab

Projections of bent / nonbent 0° bars:

Min. front / rear:
Max. front / rear:

Measure the projection of a bar from the end of the bar to the center of the intersecting bar. When a bar is bent at an end, the projection value is based on the nonbent bar.
The projection value consists of an absolute value in [mm] and a multiple of the diameter of the 90° bar. For the second part of the value, enter the factor by which to multiply the diameter. You can use a fraction of the bar length to specify the maximum projections of straight bars.

Projections of bent / nonbent 90° bars:

Min.:
Max.:

Measure the projection of a bar from the end of the bar to the center of the intersecting bar. When a bar is bent at an end, the projection value is based on the nonbent bar.
The projection value consists of an absolute value in [mm] and a multiple of the diameter of the 0° bar. For the second part of the value, enter the factor by which to multiply the diameter. You can use a fraction of the bar length to specify the maximum projection of straight bars.

Bars can only be welded if the following criteria are met:

At least two 90º bars must be available for each 0º bar.

At least two 0º bars must be available for each 90º bar.

Click the relevant diameter d1(0°) in the table and enter the required values.

"Welding5" tab

Zones locked for 0°/90° bars:

Specify the position and width of locked zones when bars are bent. As opposed to the general definitions in the configuration of attached reinforcement, you can make diameter-specific definitions here. You can use the configuration of attached reinforcement to specify which definition is used.
The locked zones 1 and 2 usually come at and after the bend; the locked zone 3 is used to define zones locked before the bend.

If you defined several machine-dependent bending pin diameters on the Welding2 tab, the number of starting points and end points entered in the From: and To: Boxes of the locked zones must be exactly the same as the number of entries in the Bending pin diameter box. Use semicolons to separate the values. You can use a dot or a comma for the decimal separator.

You can only enter values when the Can be used as a bent bar option is selected on the Welding2 tab.

Check maximum number of bars to be bent at the same time:

Depending on the bending machine used, the number of bars that can be bent simultaneously can be limited. In this case, select the check box and enter the Maximum number.

If a mesh contains several diameters in one bending line, the program adds up the number of all bars, comparing this value with the smallest value that is defined for the diameters used.

Overlap Length

Enter a diameter-dependent Overlap length. The program uses this value to create the lap joints of the attached reinforcement when the Mesh joint option is selected and the Depends on diameter (catalog) entry is selected for the Min. overlap parameter option on the Mesh 2 tab in the Gen. Basic Reinf. configuration entry in the configurations for attached reinforcement.

Note: If PLANBAR creates a mesh with two diameters in one direction or both directions, PLANBAR always uses the greatest overlap length defined for the corresponding direction.

"->Fact." tab

Assignment of entries to factories.

The selected entry applies to the selected factories only. If no factory is selected, the entry applies to all factories.
