Shear key in thick elevated slab, acceptabe?
Shear key in thick elevated slab, acceptabe?
(OP)
I have to anchor a truss on top of a thick elevated slab.
Horizontal reaction is very high. Instead of anchor bolts I have elected to use a couple of shear keys(profiles attached to base plates and embedded into concrete, to be grouted later)
This will eat up some thickness of the slab.
How bad is this imagination of mine?

Then yours are inserts, so one likely would think in degraded strengths for the thing. Some trapecial shape of the key may be required, and good and special mortars of nil retraction maybe also with special adhesive preparations of the surface.
You may as well pierce the whole slab and then lock from below if the space is available, for an entirely understandable even if simplified introduction of the load. If close to an edge, do not for get to check if spalling will be induced by any outwards force.

thanx for the lightning fast resp. I am now also interested in the adhesive used with the grout(mortar). Wanna talk about that?
