Guidelines for anchor bolts in brick and mortar deck 1

Does not seem like a great idea to try to resist moment using this substrate.

Why is that?

So bolts are supposed to be anchored to the masonry? Not a good idea in my opinion. You could have a tensile failure of a brick or the whole brick pulled out of the mortar. Why not make a concrete footing below the masonry?

First - I am not sure I have ever seen a "brick deck", though maybe that is common outside of the US?

Though I guess I would start by looking at the various available anchor products available for anchoring into brick, and the associated limitations for each. In the US, the documentation for most of these anchors is for multi-wythe brick walls only (not decks) and have relatively large spacing requirements, due to the limited localized strength of the brick assembly. The allowable tension capacity of these anchors is relatively small, much less than would be developed with moment you are describing (if 8" anchor spacing T = 16000 in*lbs/8in = 2000 lbs.). Plus, the shear loads would need to be addressed.

If I am envisioning the "brick deck" correctly, I would be surprised if you could get something to calc out.

Hope this helps

Just ask the anchor supplier what their rating is for brick and mortar substrate.

I suspect you won't find any anchor suppliers who will agree to that. Then put a proper foundation down.
