Stirrup reinforcement (67)

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

Reinforcement created


Situation	More information
	A concrete beam with main stirrups.

Use the Parameters tab to define stirrup properties.


Option	Description
Prefix	Prefix for the part position number.
Start number	Start number for the part position number.
Name	Tekla Structures uses the name in drawings and reports.
Size	Diameter of the reinforcing bar.
Grade	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.
Class	Use Class to group reinforcement. For example, you can display reinforcement of different classes in different colors.

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

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


Option	Description
Angle	Enter a value between -180 and +180 degrees.
Radius	Enter the internal bending radius of the hook.
Length	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.

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.

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

You can define six zones for the distribution.


Option	Description
Symmetric	Define whether the same spacing and bundling properties are used at the start and end of the part.
N	Number of stirrups.
Space	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.
Bundling	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	Target 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.
Stirrup spacing type	Exact 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.

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

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.


	Description
1	Define the cover thickness of the opening to control where the first full height stirrup is placed.
2	Define the minimum hole size.


Option	Description
	No reinforcement around the opening.
	Reinforcement is created around the opening.

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