About Configuration Tables

Configuration tables are highly recommended to work with Concrete Structures 3D Design. Rebar Configuration tables are dedicated for the design of reinforcing bar object types with only certain possible dimensions (mostly manufactured items). For example a rebar profile with only a specific diameter or certain mechanical properties. It allows you to define only the manufactured configuration of your object. It is also possible to manage the BIM attributes with this tool.

This page discusses:

Description

The configuration involves the bar profile and diameter value that are independent. Instead of creating several rebar object types with the same profile but with different diameters, we recommend you to use a configuration table.

An accurate format is expected for such a configuration table:

Item / Row Description Mandatory Attribute
The first row must contain at least the Designation as a title for the first column
Designation Name of the configuration Yes
IfcReinforcing BarType

To overload an IFC attribute, the column title must be formatted as PSetName_PSetParameterName (example : IfcReinforcingBarType_NominalDiameter)

No
PhysicalDiameter Real diameter of the bar (with rib thickness). No
BendingRadius Default bending value. No
HookRadius, HookLength, HookAngle Default hook values. No
CoverThickness Covering Default value. No
Layer_Color RGB color code separated by points. No
Template_ To overlay a user- defined attribute, the column title must be formatted as Template_ParameterName (example : Template_A) No
For optional parameters, the cell can be left blank if there is no need to specify the value for a given designation.

Rebar Configuration Table Example

The example below shows a rebar configuration table:

All the designation strings of the first column are displayed in the Rebar Creation command if the reinforcing object type that is selected is linked to a configuration table. Once a designation is selected in the rebar creation command, the related physical diameter is used to generate the geometry of the rebar layer. The weight of this layer is also computed according to the value given in the VolumicWeight column. If the PhysicalDiameter column or the VolumicWeight column is not filled in, the nominal diameter and the default steel volumic weight (7850 kg/m3) are used.

As an example, in the Rebar Support flag that enables to handle the axis base system input role, the cover thickness that is displayed (marked 1 in the picture below) is retrieved from the configuration table associated to the reinforcing bar object type.

Note: If no configuration table is associated, then, the cover thickness is retrieved from the preferences.

Configuration Tables Samples

Two configuration tables are provided along with Concrete Structures 3D Design. These consist in the most commonly used configuration tables, available in the <install path>\startup\Civil\Rebars. For more information, see European Rebar_Configuration as an example.
