Rebar set properties

Use the property pane or the contextual toolbar to view and modify the properties of the rebar sets. The file name extension of the property file is .rst.

General

Option Description
Name

User-definable name of the bars.

Tekla Structures uses bar names in reports and drawing lists, and to identify bars of the same type.

Grade

Steel grade of the bars.

Grade-size-radius combinations are predefined in the rebar catalog. Click the ... button in the property pane to open the Select rebar dialog box. The dialog box shows the available bar sizes for the chosen grade. You can also select whether the bars are main bars, or stirrups or ties.

Size

Diameter of the bars.

Depending on the environment, the nominal diameter of the bars, or a mark that defines the diameter.

Bending radius

Internal radius of the bends in the bars.

Bending radius complies with the design code you are using. Main bars, stirrups, ties, and hooks usually have their own minimum internal bending radii, which are proportional to the diameter of the reinforcing bar. The actual bending radius is normally chosen to suit the size of the mandrels on the bar-bending machine.

Automatic values are shown in square brackets, for example [120.00].

Class

Used to group reinforcement.

For example, you can display bars of different classes in different colors.

Numbering

Numbering series of the bars.

Special

Option Description
Follow edges

Select whether the rebar set guideline attempts to follow the leg face edges that are located between the guideline end points.

Layer number

Defines the order of the bar layers. The smaller the layer number, the closer to the concrete surface the bar layer is. You can use both positive and negative numbers.

If you do not define the layer numbers, Tekla Structures arranges the bar layers according to their creation order. The bar layer that is created first is closest to the concrete surface.

You can also adjust the layer order by using these options on the contextual toolbar:

Note that if you copy properties from one rebar set to another, the layer number is not copied.

Distribution

Option Description
Start offset

The offsets at the start and end of the guideline.

By default, Tekla Structures calculates the offset values according to the concrete cover settings and bar diameter. Automatic values are shown in square brackets, for example [32.00].

Note that the automatic offset values may change if the outermost rebar set bars are split by splitters and the split bars would end up in the concrete cover area.

End offset
Creation method

How the bars are spaced. For more information, see Spacing options.

Target spacing value
Exact spacing value
Exact spacing values
Exclude

Which bars are omitted from the rebar set.

Advanced: Rounding

Option Description
Straight bars

Define whether the lengths of straight bars, first and last legs, and intermediate legs are rounded, and whether the bar lengths are rounded up, down, or to the nearest suitable number according to the rounding accuracy.

First and last legs
Intermediate legs
Rounding up at splitters

At splitter locations, define how much the bar lengths can be rounded up.

Advanced: Step tapering

Option Description
Type

Define whether the bars are step tapered, and how the tapering steps are created.

The options are None, Distance, and Number of bars.

If you select the Number of bars option, enter the number of bars in one tapering step.

Straight bars

If you select the Distance option, enter the tapering step values for straight bars, first and last legs, and intermediate legs.

First and last legs
Intermediate legs

Advanced: Minimum lengths to be created

Option Description
Minimum bar length

Use to prevent Tekla Structures from creating reinforcing bars that are too short. This setting is primarily for straight bars. Enter the minimum bar length as Distance or as Coefficient of bar diameter.

Minimum straight start/end leg length

Use for bent reinforcing bars. Enter the minimum leg length as Distance or as Coefficient of bar diameter.

IFC export

For IFC export, select an option in IFC entity and in Subtype (IFC4). The available subtypes depend on the selected IFC entity.

You can select the IFC4 subtype among the predefined options, or you can select USERDEFINED and then enter any text in User-defined type (IFC4).

More

Click the User-defined attributes button to open the user-defined attributes of the rebar sets. The file name extension of the user-defined attribute file is .rst.more.

You can use user-defined attributes to define or override settings, such as bar layer prefix and number, or grouping settings.
