Usage of shearheads in flat slabs
Usage of shearheads in flat slabs
(OP)
Dear All! I was wondering if someone of you has experience in using "shearheads" for punching shear resistance in flat slabs.
My actual question is: Are shearheads commonly used in Europe?
According to guide ACI 421.2R-10, shearheads are not common in North America, even though the ACI code permits them. In Europe, Eurocode does not even mention "shearheads". However, I was wondering if there is any experience in using them in Europe.
p.s.: shearhead = steel profiles embedded in the slab at slab-column joint.

Here Shearhead means "stud-rail reinforcement AROUND column" NOT "embedded steel profiles in slab joint.

One was for a steel stanchion supporting an RC slab, stanchion was continuous through the slab. The other was to allow openings to be cored at a future date close to the column location without compromising the slab capacity.

I would agree they are not common when you consider all buildings (there are lots of steel buildings, wood buildings, other construction types, etc) but when it comes to two-way concrete, they're all over the place.

Stud rails are common, but the question was about fabricated shear heads. Different things.
