Example: Create a nested connection with stiffeners

In this example, you will create a nested custom connection that consists of and end platecomponent object that represents a plate welded perpendicular to the end of the component secondary part

, a bolt groupgroup of bolts that forms a connecting building object between an assembly main part and secondary parts

The number of bolts in a bolt group depends on the bolt group shape and the values of bolt distances.

, welds, and two Stiffeners (1003) components. The stiffeners are optional, which means that you can choose whether or not to create them when using the component in a model.

  1. Add an End plate(1) part that represents a flat structure

    (1) In some contexts, for example in analysis, the term plate object may be used to refer to plates.

    (2) plate that represents a steel structure

    (2) Plate is mainly used as a connection piece or as a floor plate.

    component.

  2. Explode the end plate component.
  3. Add two Stiffeners (1003) components.

  4. Create a nested custom componentcomponent that the user creates and uses for creating model objects whose composition the user can modify as a group

    that contains the stiffeners and the end plate objects.

    1. Click the Applications & components button in the side pane to open the Applications & components cataloguser interface for displaying or modifying information in categorized lists

      For example, profile catalog and shape catalog are catalogs.

      .

    2. Click the Access advanced features button and select Define custom component.
    3. In the Type list, select Connection.
    4. In the Name box, enter End plate with stiffeners.
    5. Click Next.
    6. Make an area selectionmethod of selecting objects that are included in a certain rectangular area of a model

      In addition to the selected area, selection switches and selection filters control which object types are selected.

      (from right to left) to include the following objects in the nested componentcomponent that consists of several components

      Nested components include elements that are modeled as sub-components.

      : the column, the beam, the stiffenercomponent object that represents a structure that strengthens a steel beam or column

      Stiffeners are usually plates.

      Stiffeners are used to prevent web buckling at supports or concentrated loads.

      components, and all the end plate objects.
    7. Click Next.
    8. Choose the column as the main part(1) part that exists in a building object and that determines the position number for the assembly or cast unit and the direction of assembly or cast unit drawings

      (1) Main part can be an assembly main part or a cast unit main part.

      (2) input part that the user selects first when creating a component

      (2) Connections and details always have a component main part.

      of the nested component, and then click Next.
    9. Choose the beam as the secondary part(1) part that exists in a building object and that is connected to the main part

      (1) Secondary part can be an assembly secondary part or a cast unit secondary part.

      (2) input part that the user selects after selecting the component main part when creating a component

      (2) A component can have none, one or more component secondary parts.

      of the nested component, and then click Finish.
      Tekla Structures creates the nested component.

  5. Select the nested component you just created.
  6. Right-click and select Edit Custom Component.
  7. In the custom component editortool that is used for modifying component that is created by a custom component, and for creating dependencies between component objects and other model objects

    , click the Display variables button.


    The Variables dialog box opens.

  8. Create the following parametric variables:
    1. Click Add to create a new parametric variablevariable used to define a value for a parametric property

      A parametric variable does not include a dependency.

      For example, name, material grade, and bolt size are parametric variables.

      P1.
    2. In the Value type list, select Yes/No.
    3. In the Label in dialog box box, enter Create Stiffener 1.
    4. Click Add to create a new parametric variable P2.
    5. In the Value type list, select Yes/No.
    6. In the Label in dialog box box, enter Create Stiffener 2.

  9. Link the variables to the Creation property of the two stiffeners:
    1. In the Custom component browser , browse for the uppermost Connection.
    2. Right-click Creation and select Add Equation.
    3. Enter P1 after the equal sign, and then press Enter.
    4. Browse for the second Connection.
    5. Right-click Creation and select Add Equation.
    6. Enter P2 after the equal sign, and then press Enter.

  10. Save and close the nested component.

You now have the following options in the nested component's dialog box:
