Column Shoe Connection

1. Purpose and description



This tool is used to create a column shoe connection between a column and a foundation. The foundation can be a footing, column, beam, or slabplate that represents a concrete structure

In Tekla Structures, a slab is created by picking three or more points.

Slab may be part of a floor, for example.

. The tool creates column shoes, anchor bolts, cuts and fittings, and the required additional reinforcing for column splice area.

2. System requirements

Please note that in order to let the connection create the embedbuilding object that represents an object that is to be cast into a concrete structure and that is used to connect structures or as an aid when constructing a structure

For example, a cast-in socket is an embed that is placed in concrete structures to allow parts to be fastened together on site. In Tekla Structures, embeds are typically steel parts and they are added to cast units as sub-assemblies.

connectors these embed components shall be existing in your current component catalogcatalog that contains all system components and custom components, and the macros and applications

. You can find example embeds and manufacturer embeds from Tekla Warehouseservice for collaboration and for storing and sharing Tekla Structures content

In Tekla Warehouse the content items are stored in collections. Tekla Warehouse includes the Tekla Warehouse Service and the Tekla Warehouse web site.

Tekla Warehouse is one of the Tekla Online services.


3. Installation

To install the extension:

  1. Download and run the TSEP-file. 
  2. Follow the instructions

4. Usage

To use the extension:

  1. Double click the component “Column Shoe Connection” from applicationpart of Tekla Structures functionality that is developed in order to extend the capability of Tekla Structures but that is not included in the Tekla Structures installation

    & component cataloguser interface for displaying or modifying information in categorized lists

    For example, profile catalog and shape catalog are catalogs.

    . If component catalog is not visible you can press Ctrl+F to open the component catalog.
  2. Fill in the desired properties and click Apply. To see more detailed description of all properties please see the paragraph 5 in this document.
  3. Pick 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.

    (foundation) in model viewview that is represented in the modeling mode

    Model view is available also in the drawing mode and it is represented in its own window.

  4. Pick 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.

    (column) in model view.
  5. The connection is created and you can continue picking other connection

5. Properties

This extension component has four tab pages. The properties in each tab page are described in details on following paragraphs.

5.1 Picture


Property Description
Auto Attribute file You can choose to use predifened settings with auto attribute file. Tool finds all attribute files that can be found in you project-, firm- or system folder. If you desire to use only the settings defined in tool dialog, you choose "No auto attribute file". More about defining auto attribute files in chapter 6.

Manufacturer auto attribute files can be downloaded from Tekla Warehouse with serach term 'Columns Shoe connection'.

Allow Auto Attribute file override Choose if you want to enable fileds that can be defined in auto attribute file
  1. No  = Fields are disabled and values comes from auto attribute file
  2. Yes = Fields are enabled and values comes from auto attribute file
  Select the number of shoes and bolts in connection
  1. Four (for rectangular and circular columns)
  2. Six (middle shoes and bolts in local y-coordinate side)
  3. Six (middle shoes and bolts in local z-coordinate side)
  4. Eight


 With these options you select the embed type for shoes and anchors.
  1. Columns shoe embed to the corners
  2. Columns shoe embed to the middle 
  3. Anchor bolt to the corners
  4. Anchor bolt to the corners

If you are using auto attribute file, only the first dropdown is active (A). There you select the embed from list that has been defined in the auto attribute file.

If you are not using auto attribute file, you select the embed component from the applications component catalog. You can open the catalog by picking the button on the right (B).

Attribute file dropdown is a list of attribute settings that are found to chosen component (C).

5.2 Dimensions

All dimensions can be predefined in the auto attribute file. Even you use auto attribute file, you can override the values by entering values to field boxes. 

Property Description

Column shoe recess width and middle column shoe recess width

Width of the cut object that is created for the column shoe embed.
Columns shoe recess height and middle column shoe recess height
Height of the cut object that is created for the column shoe embed.
Thickness of grouting
Gap between column bottom and foundation top level.
Bolt distance from column edge and middle bolt distance from column edge
Distance of the bolt embed from the edges of column.
Protrustion of the bolt and protrustion of the middle bolt
Distance of the bolt embeds creation points to foundation.

5.3 Additional Reinforcing.

All values in white background can be predefined in the auto attribute file. Values in yellow backround can't be defined in the auto attribute file.  Even you use auto attribute file, you can override the values by entering values to field boxes.


Property Description
Concrete cover thickness Controls stirrups cover thicknesses from concerte
Overlap for round stirrups
For circular columns, round strrups are automatically used. This controls the overlap distance for those.
Stirrup size and grade
Select the stirrup size and grade.
Itermediate stirrup width
When middle column shoes are used, intermediate stirrups are automatically created. This controls the width of those stirrups.
U bar size and grade Select the U-bar size and grade.
U bar number and spacing 
Control the number of U-bars in different edges. Type the exact spacings if needed. 
U bar distances
Define the leg lengths of U bars and distances from concrete covers. 
Stirrup number, spacing and distances
Define condensing stirrup spacing for bottom of column and to the top of column shoe splice bars. Define target spacing to middle of bottom and top.

Hight of column shoe is defined in the value box on the left. That for defining the condensing stirrup spacings.

5.4 Attributes

None of the values in this tab page is coming from the auto attribute file.

6. Auto Attribute file

With 'Auto Attribute file'  embed manufactures can provide their standard property values to support their detail solution. Embed manufactures can provide definitions files in Tekla Warehouse with their product library.

Column shoe connection lists all -xml files that are named ColumnShoeConnection_ManufacturerX.xml , where word 'ManufacturerX'  can be chosen. In that case the word ManufacturerX is listed in the auto attribute dropdown list. 

Column Shoes and anchor bolts defined auto attribute file are shown in the dropdowns in 'Picture' tab page

Auto attribute file can be located in your XS_PROJECT / XS_FIRM or environment folder.

6.1 Example of setting the .xml file

You can add new column shoe and anchor bolt Custom Components to tool by adding them and required data to file as shown below.

Anchor bolts:

Column shoes:
