Base plate (1004)

Base plate (1004) creates a base platecomponent object that represents a plate welded to a column base

Base plates are used to distribute the concentrated load of the column over a wider area.

that is connected to a column end.

Objects created

  • Base 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.

  • Shimcomponent object that represents a plate that is used for filling clearances and gaps on the construction site

    plates (optional)

  • Leveling plate (optional)

  • Groutbuilding object that represents the filling of seams between parts, or holes or voids in a part with grout

    Grouting can be used when connecting parts with anchor bolts or rods, or in seams between panels, for example.

    Grout is flowing concrete that hardens after application.

    (optional)

  • Shear keycomponent object that represents a short steel part welded to the bottom of a base plate

    (optional)

  • Extra plates connecting the anchor rods

  • Anchor rods

  • Bolts

  • Additional component (optional)

Before you start

Create a column.

Selection order

  1. Select 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.

Example: Add a base plate and anchor rods using Base plate (1004)

In this example, you will add a base plate detail and anchor rods to a column.

  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. Enter base plate in the search box.

    To view the thumbnail images of the components in the search results click.

  4. Select the column.
  5. Pick a position at the base of the column.

    Tekla Structures automatically adds the base plate when you pick the position.

  6. Next, modify the anchor rod dimensions.
    1. Switch on the Select components switch to more easily select components.
    2. Double-click the component symbolsymbol in a model that indicates a component type, functions as a link to component properties, and can be used to control component objects
