transfer slab - beam shear and punching shear reinforcement
(OP)
Hi
I have a transfer slab/beam where the shear stresses are high. With propriety stud rail reinforcement, I understand this to be fully developed vertical reinforcement which increases the shear capacity. My question is whether anchored shear ligs / links would perform the same task.
Also, are there any methods out there that I can use to increase the shear capacity of a concrete slab band. The idea's I have are to stress the slab and to use a high grade steel for shear reinforcement. What is the highest grade steel that is available on the market. Is there any grades higher than 500MPa or 75ksi?
Thanks.

For your 2nd question - there is very high grade steel but ACI sets limits on what you can use to insure deformations compatibility. If you are outside the US then check your local code, there are probably similar limits.

I'm not a fan of studrails. Have you considered a structural steel shear head?

@RE/hokie, good to see you guys are still going strong. I kinda got lost in the woods there for the last year.
