Summary
Adding a shear lug allows PROFIS Engineering to account for an additional steel element designed to resist shear loads transferred from the anchor plate to the concrete. Defining the shear lug ensures that the software applies the correct assumptions for shear resistance, load transfer and interaction with anchors according to ACI design provisions.

Step-by-step instructions
- Open the Profiles tab
In your Anchoring to Concrete design workspace, navigate to the Profiles tab on the left-hand side of the screen.
-
Enable the Shear lug option
Under Profiles, enable the Use a shear lug option if you intend to include a shear lug.
Choose the desired shear lug from the available predefined options. -
Select the Shear lug size
Choose the required Shear Lug Size from the dropdown menu. - Define a custom profile (optional)
If you need a non-standard configuration, select Custom to define your own profile parameters.
- Adjust the Shear lug orientation
Use the rotation controls to turn the shear lug left or right.
Each click rotates the shear lug by 90 degrees.
Tip
It makes sense to use an anchorage 1) when a calculated shear design strength for the anchors is less than the factored shear load assumed to be acting on them 2) when the number of anchors needed for shear transfer is impractical or 3) when an alternative means for shear transfer into the concrete is desired.
