Beam end reinforcement (79)

Beam end reinforcement (79) creates reinforcement for the end of a concrete beam or strip footing.

Bars created

  • 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)

Description
1 Horizontal U bars (type 2)
2 Horizontal U bars (type 1)
3 Oblique bar (type 4)
4 Vertical U bars (type 3A)
5 Stirrups (type 5A)
6 Vertical U bars (type 3B)
7 Stirrups (type 5B)

Use for

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

  1. Select concrete beam or strip footing.

  2. 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.

Option

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.
