Create a tapered or spiral reinforcing bar group

For example for rectangular concrete parts with variable cross sections, you can create tapered reinforcing bar groups by specifying the bar shape at each cross section. For concrete parts with a uniform cross section, you can also create spiral reinforcing bar groups, and it is sufficient to pick two points to define the distribution area of the bar group. If the part shape is not rectangular, an alternative bar shape can be defined.

Use the Rebar group type list in the reinforcing bar group properties to select or change the bar group type.

To create a circular spiral bar group, use the Bar group > Circular group ribbon command and the Circular rebar properties instead.

  1. On the Rebar tab, hold down Shift and click .

    The Rebar group properties open.

  2. In the General section, select a tapered or spiral option from the Rebar group type list.
  3. If needed, enter or modify the other bar properties.
  4. Select the part to reinforce.

    Tekla Structures attaches the bar group to the part.

  5. Pick points to define the shape of the bar at the first cross section.
  6. Click the middle mouse button to finish picking.
  7. Depending on the bar group type and the number of cross sections, do one of the following:

    • At the second and each subsequent cross section for a tapered bar group, pick points to define the bar shape. Then click the middle mouse button to finish picking at the cross section.

    • For a spiral bar group, pick two points to define the distribution area of the bar group.

Tekla Structures creates the reinforcement.

Reinforcing bar group types

Option Description Example

Normal

Not tapered.

Pick two points to define the distribution area of the bar group.

Tapered

One bar dimension changes linearly in the group.

Tapered ridge

One bar dimension changes linearly in the group. The dimension is longest in the middle of the group.

Tapered curved

One bar dimension changes along a curve. The dimension is longest in the middle of the group.

Tapered N

One bar dimension changes linearly between N cross sections. Enter the number of cross sections in the Number of cross sections box.

Spiral

The reinforcing bars rise in a polygonal or circular shape along the longitudinal axis of the part.
