Horizontal U-shaped bars (types 1 and 2)
-
Vertical U-shaped bars (types 3A and 3B)
-
Oblique bar (type 4)
-
Stirrups (types 5A and 5B)

Situation |
More information |
---|---|
Standard beams |
Use bars 3A and 5A for the beam end. |
Dapped beams |
|
Beams with anchor bolt hole in the notched area |
|
Beams and strip footings that have a rectangular cross section |
Do not use for
Parts that have irregular cross sections.
Before you start
-
Create the concrete beam or strip footing.
-
Calculate the required area of reinforcement.
Picking order
-
Select concrete beam or strip footing.
-
Pick position.
Picture tab
Use the Picture tab to define concrete cover thickness, distances from the concrete surface to the bars, and angle of bar 4.
Bars tab
Use the Bars tab to define which bars to create, bar dimensions, and to slice bars 3A and 3B.
Horizontal U bars 1 and 2
Use the following options to create bars in the lower area of the beam end, in the horizontal planes (bar type 1):
Option |
Description |
---|---|
|
Two bars on each plane. One in the middle of the beam end, the other extending to the sides of the beam. |
|
One bar on each plane, extending to the sides of the beam. |
|
One bar on each plane, in the middle of the beam end. |
|
Two identical, overlapping bars on each plane. |
To create bars in the upper area of the beam end, around a hole, enter dimensions for bar 2.
Vertical U bars 3A and 3B
To create vertical U-shaped bars, enter dimensions for:
-
Bar 3A: for the notched area of the beam.
-
Bar 3B: for the higher part of the beam.
Splicing bars 3
You can create vertical U bars (bar type 3) of two bars joined with a splice. To do this, use the following list box on the Bars tab:
If you choose to splice bars, you can select the splice type:
Option |
Description |
---|---|
Lap up |
Creates a lap splice above the horizontal center line of the beam end. |
Lap down |
Creates a lap splice below the horizontal center line of the beam end. |
Lap both |
Creates a lap splice centered to the horizontal center line of the beam end. |
Coupler |
Creates a coupler. |
Weld joint |
Creates a welded joint. |
For lap splices, you can define the lap length L and whether the bars are on top of each other or parallel to each other.
For all splice types, you can define the offset of the splice center point from the horizontal center line of the beam end.
Stirrups 5A and 5B
To create stirrups for beam ends, enter dimensions for:
-
Bar 5A: for the notched area of the beam.
-
Bar 5B: for the higher part of the beam.
Groups tab
Use the Groups tab to define grouping properties of bars.
Enter the number and spacing of bars in each group of bar types. If the spacing varies, enter each value individually.
Attributes tab
Use the Attributes tab to define bar properties.

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