Create braces

Tekla Structural Designer allows you to create single braces, or pairs of braces (in an X, K, V, or A configuration).

Braces are single span members with pinned end connections that are only able to resist axial compression and tension. Their purpose is to provide lateral stability to your structure.

Tip: You can specify rigid frames to achieve the same effect as by using braces. If necessary, you can use both rigid frames and braces within a single structure.

Element loads cannot be applied directly to a brace itself and moments due to self weight loading are ignored.

Setting out braces

Each steel brace is placed on an insertion line between points, with its geometry being drawn to reflect the major and minor snap points and any offsets specified in the brace properties.

Note:

The alignment snap points and offsets have no effect on the positioning of the solver elements created to represent the braces in the solver models, as these will be created directly between the insertion points.

Specify the brace material, pattern and section size

Before creating a brace, you need to specify its material, pattern and section size. For more information, see the following instructions.

  1. Do one of the following:
    To Do this
    Specify a steel single brace or pattern

    1. On the Model tab, click the arrow under Steel Brace.

    2. In the list, select Brace for a single brace; or choose an X, K, V, or A pattern.

    To Do this
    Specify a cold formed single brace or pattern

    1. On the Model tab, click Cold Formed.

    2. In the list, click the arrow next to Brace.

    3. In the list, select Brace for a single brace; or choose an X, K, V, or A pattern.

    To Do this
    Specify a timber single brace or pattern

    1. On the Model tab, click the arrow on the right side of Timber Brace.

    2. In the list, select Brace for a single brace; or choose an X, K, V, or A pattern.

  2. In the Properties window, go to the Section property.
  3. Click the arrow on the right side of Section.
  4. In the list that appears, click <New\Edit...>.

    The Select Section dialog box opens.

  5. Select the desired section, and click Select.
  6. In the Properties window, adjust the remaining properties according to your needs.

Create a single brace

Note: Although it is possible to model A or V brace configurations using individual brace members instead of a brace pair, Tekla Structural Designer is then not able to calculate the notional loads or EHFs (Equivalent Horizontal Forces) correctly. In this case, elements of the vertical loads that are supported by the bracing system are lost, and are not included in the notional load or EHF calculations.
  1. Specify the brace material and section size.
  2. Click the start point of the brace.
  3. Click the end point of the brace.
    Tekla Structural Designer creates the brace.
    Tip: If you are using a point along an existing member as either the start or end point, do the following:

    1. Click the existing member to view its points.

    2. Click the point that you want to use, or type the distance from the start of the member to the desired point.

Create an X, K, V or A brace

  1. Specify the brace material, pattern and section size.
  2. Click to identify a bottom corner of the bay that you want to brace.
  3. Click to identify the opposite bottom corner of the bay.
  4. Click to identify a top corner of the bay.
  5. Click to identify the opposite top corner of the bay.

    Tekla Structural Designer creates the brace pattern within the selected area.

    X pattern
    K pattern
    V pattern
    A pattern

Specify a brace as tension only or compression only

You can move the end nodes of individual steel, concrete, cold formed, or timber braces in both 2D and 3D views. For more information, see the following instructions.

Once a brace has been created, you can specify it as Tension only or Compression only in the Properties window.

Note:

Tension only and Compression only members are non-linear elements and therefore require non-linear analysis. If linear analysis is performed, they will be treated as linear elements.

  1. Select the brace.
  2. In the Properties window select either Compression only, or Tension only as required.

Modify the position of a brace

You can move the end nodes of individual steel, concrete, cold formed, or timber braces in both 2D and 3D views. For more information, see the following instructions.

To move an entire brace, see: Move objects.

  1. Select the brace.
  2. Select the end node that you want to move.
    Note:

    Ensure that only the desired end node is highlighted in the Select Entity tooltip.

  3. Click a grid or construction point where you want to move the end node.

    Tekla Structural Designer redraws the brace, moving the end node to the selected point.
