U Bar of concrete slab (63)

U Bar of concrete slab (63) automatically generates U bars reinforcement for concrete slabs.


  • Precast concrete RC slabs and PC panels (both solid and sandwich)

  • For cast-in-situ slabs (both vertical and horizontal).

Use for

To create U bars to an already created concrete slab complete with its main and secondary reinforcement.

Create the slab’s main reinforcement

  • with existing slab reinforcement components (e.g. Pilecap reinforcement (76), Pad footing (77), Slab bars (18), Reinforcement mesh array in area (89))

  • manually with the tools on the Concrete toolbar (e.g. single bar, bar groups or mesh).

Before you start

Existing components must be created previously in order to use this reinforcement tool.

U bars tab

Use the U bars tab to define the U bar properties.



U Bar UB1

U Bar UB2

Use the fields to specify

  • Top concrete cover.

  • Bottom concrete cover.

  • Side concrete cover.

  • Top leg length.

  • Bottom leg length.

  • End dist




Prefix 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.


Use Class to group reinforcement.

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

Bending radius

Internal radius of the bends in the bar.

Creation method

Spacing options for the bars.

Target spacing value

Target spacing value.

Tekla Structures tries to distribute the U bars as closely as possible according to the entered value.

This field is available if you set he Creation method to Equal distribution by target spacing value.

Exact spacing value

Exact spacing value.

Tekla Structures creates fixed, equal spaces between the reinforcing bars.

By exact spacing

Define several spacing values between the U bars.

Tekla Structures distributes the bars using the values you enter in the field.

Enter all spacing values, separated by spaces. You can use multiplication to repeat spacing values. For example, enter 5*200 to create five spaces of 200 mm.
