I have a very old existing building. The exterior walls are load-bearing clay brick walls. I suspect the bricks are solid clay. I need to add a new steel beam to support a point load. Can you recommend an anchor that can transfer the reaction through shear into the brick wall? The unfactored DL + LL is 5.25k (7.5k factored). It's acceptable to use multiple anchors to get to the required load.
Hi John.
Thank you for reaching out.
Since Hilti is not a registered design service, we are unable to recommend a specific anchor that will work for your design. However, please see below for some of the anchors we have with published test data for anchoring into clay brick:
HIT-HY 270
- Product Technical Guide (Table 15 for solid multi-wythe brick)
- Operating Instructions
For HIT-HY 270 into solid clay brick, Hilti has published data for multi-wythe solid brick, at a minimum of three wythes. For two wythes of brick, please refer to this AskHilti article.
The clay brick data for the HLC can be used for one wythe or multiple wythes of brick.
For design help, engineers typically utilize Hilti’s PROFIS Engineering Suite software to perform calculations based on the specific conditions of the project. Click here to access the software from Hilti’s website. Hilti has several how-to videos to help users get started with the PROFIS Engineering Suite software. For additional information on the various design modules/methods, Hilti provides several on-demand Ask Hilti webinars on topics such as base plate design, anchoring to masonry, and anchoring to concrete-over-metal deck.
Ultimately, the decision and approval of anchor selection would be up to the Engineer of Record (EOR) on the project.

Katelyn
