User-definable name of the bars.

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

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.

Diameter of the bars.

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

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].

Used to group reinforcement.

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

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.

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

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.

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.

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.

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).

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).

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.

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

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.

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