Stirrup reinforcement (67)

Stirrup reinforcement (67) creates stirrup reinforcement for a beam, a panel, or a rectangular slab.

Reinforcement created

  • Main stirrups

  • Hooks (Optional)

Use for


More information

A concrete beam with main stirrups.

Before you start

  • Create the concrete part.

  • Calculate the required area of reinforcement.

Parameters tab

Use the Parameters tab to define stirrup properties.

Reinforcing bar




Prefix for the part position number.

Start number

Start number for the part position number.


Tekla Structures uses the name in drawings and reports.


Diameter of the reinforcing bar.


Strength of the steel used in the reinforcing bars.

Bending radius

Internal radius of the bends in the bar.

You can enter a separate value for each bar bend. Separate the values with spaces.

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.


Use Class to group reinforcement.

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

Hook type

Define the hook type separately for the start and end of the part. The options are:



No hook

Standard 90-degree hook

Standard 135-degree hook

Standard 180-degree hook

Custom hook

If you select a standard hook, the Angle, Radius, and Length use predefined dimensions.




Enter a value between -180 and +180 degrees.


Enter the internal bending radius of the hook.


Enter the length of the straight part.

Stirrup shape

Select the shape of the stirrups. The options are Open, Closed, and Spiral.

Number of rounds, N*

If you select the stirrup shape Spiral, enter the number of rounds the spiraled stirrup has.

Cover thickness

Define whether the concrete cover thickness is same or different on each side from Concrete cover dropdown list.

If you select a different concrete cover for each side, enter the separate cover thicknesses.


Rotate the polygon of the rebar shape from the First stirrup and the Second stirrup. You can rotate the polygon either at each even or odd position.

Stirrup spacing tab

Use the Stirrup spacing tab to define the spacing of stirrups.

You can define six zones for the distribution.




Define whether the same spacing and bundling properties are used at the start and end of the part.


Number of stirrups.


Define the spacing of stirrups.

Use a space to separate spacing values. Enter a value for each space between the stirrups. For example, if there are 3 stirrups, enter 2 values.


Select whether to have single or double main stirrups.

Single stirrups:

Bundled stirrups:

Min hole size

Define a size limit for the holes.

Stirrup spacing type


Tekla Structures creates equal spaces between the bars, aiming the spacing value as closely as possible to the value you specify. This is the default option.


The first and last space of a zone adjust themselves to even out bar distribution. The spaces in the middle of each zone are exactly the size you specify.

Holes and recesses tab

Use the Holes and recesses tab to define how reinforcement is created around openings.

Bar behavior at holes and recesses

Select how the bars next to holes and recesses are handled.

Option Description

Cut bars

Select whether the bars are cut and which cuts are ignored.

You can select to ignore cuts by part name or class. If you ignore cuts by name, define the name. If you ignore cuts by class, define the class.

Cover thickness



Define the cover thickness of the opening to control where the first full height stirrup is placed.


Define the minimum hole size.

Reinforcement around opening

Option Description

No reinforcement around the opening.

Reinforcement is created around the opening.

Reinforcement position

If you create reinforcement around the opening, select how the reinforcement is positioned.
