Wall to wall connection

Wall to wall connection

Wall to wall connection creates a connection between two precast walls. The connection can contain a groove with or without additional shear teeth. Additionally, the connection can create reinforcing barreinforcement that represents a steel bar used to reinforce a concrete structure

The steel bars are usually ribbed and they are used to increase the tensile strength of concrete.

loops or embeds that work as connectors in the walls.

Objects created

  • Groove
  • Shear teeth or shear cups
  • U bars
  • Embeds
  • Long bar

Use for

Situation Description

Wall to wall connection with groove, shear teeth, U bars and a loose bar.

Selection order

  1. Select the first wallplate that represents a structure such as a wall or roof panel

    In Tekla Structures, a panel is created by picking two or more points.

    In cast-in-place concrete the term wall refers to a concept similar to panel.

    .
  2. Select the second wall.

    The connection is created automatically when the second wall is selected.

Edge shape tab

Use the Edge shape tab to select the wall framing type

Option Description

Wall framing type selection.

Wall framing type selection affects the wall edge shape options.

You can use the connection in three different modeling situations:

  • end-to-end
  • corner

    With this option the first selected wall is fitted to align with the exterior face of the second selected wall.

  • tee

Wall edge shape.

Select the edge shape of each wall.

Adjust the free space between two walls.

Wall edge dimensions.

To set the edge shape and dimensions independently for both walls, use the Use given dimensions option.

To make the edge shape similar in both walls, use the Same to right side option.

Groove start and end point.

You can define the start point and the end point of the groove. If you do not enter a value, or enter 0 , the groove is applied at full height of the wall.

Select to create part cuts or only extra part cuts, and define the name of the cut. You can set this separately for both walls. For part properties of extra part cuts, select a saved settings file.

Extra teeth tab

Use the Extra teeth tab to define the properties for additional shear teeth.

Option Description

Select whether additional shear teeth or shear cups are created.

Teeth or cups can also be created when there is no groove.

Dimensions of a single tooth or cup.

Location of the first tooth or cup in the first wall and in the second wall, and the spacing between the teeth or cups.

You can enter a list of spaces, for example 10*400 , or just a single value. When you enter a single value, the number of teeth or cups is calculated automatically based on the height of the connection.

Select to create part cuts or only extra part cuts, and define the name of the cut.

Connectors tab

Use the Connectors tab to select the type of connectors created.

Connector type

The content of the Connectors tab varies depending on the type of the selected connectors.

Option Description

Connector type.

  • No connectors. Only groove with or without shear teeth is created.
  • Connectors are created by using the selected embed (custom part).
  • Connectors are created by adding reinforcing bar loops. Reinforcing bar loop is formed depending on the wall framing type.

In addition, the connector can optionally create one or more long reinforcing bars along the connection.

Embeds and loose rebar

Option Description

Location of the first connector (embed) in the first wall and in the second wall, location of the last rebar/embed in the wall top edge, and the spacing between the connectors.

You can enter a list of spaces, for example 10*400 , or just a single value, for example 300. When you enter a single value, the number of connectors is calculated automatically based on the height of the connection.

You can also define the extended length of the loose long bar.

Select which embeds (custom parts) are created in each wall.

If the embed has any saved attributes, select which attributes are used.

Offset of the embed.

By default, the embed input points are in the center of the wall.

U bars and loose rebar

Option Description

Location of the first connector (reinforcing bar loop) in the first wall and in the second wall, and the spacing between the connectors.

You can enter a list of spaces, for example 10*400 , or just a single value, for example 300. When you enter a single value, the number of connectors is calculated automatically based on the height of the connection.

You can also define the extended length of the loose long bar.

Reinforcing bar loop dimensions.

The available dimension options depend on the wall framing type selected on the Edge shape tab.

Many of the dimensions have counter parts in the first wall and in the second wall. It is enough to enter one dimension and by default the counter part dimension gets the same value.

Number of bars

Number of long loose bars.

If you do not want to create a loose long bar, enter 0 as the Number of bars.

Reinforcing bar properties

Enter the properties for reinforcing bar Grade , Size , Name , Class , Prefix and Start Number.

Customization

If needed, you can create your own 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 bolted together on site. In Tekla Structures, embeds are modeled as steel sub-assemblies that are inside a concrete nested assembly.

(custom partcomponent for creating a part that cannot be created by using any existing part command or part profile

Typically, custom parts are used to create parts that have a complex composition. For example, castellated beams and sandwich panels are often created as custom parts.

) and use it as a connector.

When creating the embed, ensure that the input points are defined so that they are compatible with Wall to wall connection. The image below shows examples of the input points.

Thickening tab

Use the Thickening tab to create an extra thicknening to one or both walls.

Option Description

Select to which side of the wall the thickening will be created. The final location of the extra thickening depends on the actual framing case (end to end, L corner, T corner).

Enter the name and class for the extra thickening. Leave the input box empty to use the wall name and/or class.
