Rebar set properties

Rebar set properties

Use the property panecontrol element in Tekla Structures user interface in the form of a side pane window

The property pane can be used to show and modify the properties of model objects.

or the contextual toolbarfloating toolbar that contains commands for modifying the most common object properties

The user can customize the contextual toolbar.

The term mini toolbar is used in Tekla Structures until version 21.1.

to view and modify the properties of the rebar sets. The file name extension of the properties file is .rst.

Attributes

Option Description
Numbering Numbering series of the bars.
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 reinforcing bar catalog. Click the ... button in the property pane to open the Select Reinforcing Bar 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.

The rebar_database.inp file contains the predefined reinforcing bar catalog entries.

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.

Class

Used to group reinforcement.

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

Layer order number

Defines the order of the bar layers. Enter a number, or use the arrow buttons to change the number. The smaller the 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 order 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.

UDAs

Click the UDAs button to open the user-defined attributes dialog box. The file name extension of the user-defined attributes file is .rst.more.

Spacing properties

The file name extension of the spacing zone properties file is .rst.zones.

Option Description
Start offset

The offsets at the start and end of a rebar set.

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].

You can define whether an offset value is an Exact value or a Minimum value. If you select Minimum , the actual offset value can be bigger, depending on the spacing properties. In model views, both the actual and minimum values are shown, for example 50.00 (> 32.00), where the minimum value is in parentheses.

End offset
Length

The length of each spacing zone as an absolute value in the current length units ( Absolute ), or as a percentage of the total length of all spacing zones ( Relative ).

Only two of the three properties, Length , Number of spaces , and Spacing , can be set to Absolute or Exact at the same time.

At least one of the spacing properties needs to be flexible and yield to create a practical spacing combination. In model views, the yielding value is shown in red.

Number of spaces

Defines to how many spaces a spacing zone is divided.

You can define a flexible number, which Tekla Structures aims at ( Target ), or a fixed number of spaces ( Exact ).

Spacing

The spacing value of each spacing zone.

You can define a flexible number, which Tekla Structures aims at ( Target ), or a fixed number of spaces ( Exact ).
