How to select post-installed element and define layout in Concrete overlay module

Prerequisites

Make sure you:

• Are logged in to your PROFIS Engineering account
• Have opened the Concrete overlay module
• Have defined Concrete geometry and the Number of Zones under the Concrete member tab

If needed, refer to the article How to access the Concrete overlay module in PROFIS Engineering.

Step-by-step instructions

1. Open the Product tab
   In your Concrete overlay design workspace, navigate to the Product tab on the left-hand side of the screen. 
   Here you can define:

   • The shear connector
   • The connector position
   • The strengthening layout per zone

   

Select the Shear connector

2. Choose the product family
   Under Shear connector, select the desired injection system + fastening element combination.
   Use the arrow icon to browse available product families.

   

3. Select the product type
   Use the Type dropdown to pick the specific product. 
   This field updates automatically based on the selected family.
   Click View ETA to review the selected product approval document.

   

4. Select the size of post-installed element
   Choose the appropriate Size from the dropdown.
   The selected diameter affects:
   • Drill hole size
   • Embedment depth

   • Spacing and edge distance limits

     

Define the Connector position

5. Select the connector position method
   From the Connector position dropdown, choose one of the following:
   • Automatic
     • PROFIS Engineering automatically positions the connector and determines embedment depths
       You can choose an optimization type, such as:
       • Minimum number of anchors

       • Minimum embedment depth

         

   • User defined
     • Manually enter:
       • Embedment depth in existing member
         Embedment depth in overlay / new member

     • Use this option when embedment depths are fixed by drawings, approvals, or site constraints

       

Define the layout for each strengthening zone

After defining the connector and its position, expand Zone 1 to configure the layout.
Note: You can modify the number of zones in the Concrete member tab.

5. Define spacing in the central area (only available for user defined option)
   Enter:

   • Spacing in x
   • Spacing in y

   Use + / – buttons or type values manually.
   Spacing directly influences shear capacity distribution and connector demand.

   

6. Define spacing in edge areas (only available for user defined option)
   If applicable, enter spacing values separately for:

   • Edge area in x
   • Edge area in y

   This allows different layouts near boundaries or free edges of the overlay.

   

7. Repeat for additional zones
   If your strengthening design includes multiple regions, repeat steps 5 and 6 for each zone as required by the project.

Tip

Use the information (i) icons for guidance on connector positioning and spacing. When embedment depths are controlled by construction constraints, switch to User defined connector position to maintain full control over embedment in both the existing member and the new overlay.
