stud rails? Could you provide some information about it? thanks

Acturally the architect doesn't like drop panel or concrete capital idea cause he doesn't want to use ceiling to cover it. Now it leaves the shearheads. I'm not familiar with that, how much it can help, if we use shear head, then the column spacing can go 29.5' with 9" concrete slab? Is any site...

The design is just starting. The client is really not happy increase the thickness of the slab and suggested shearheads. Is that going to work? Acturally the deflection is fine but the puching shear around the column fail after we considered the unbanlance moment.

Who has used Carbon Fiber Reinforced Polymers to strenthen punching shear of reinforced concrete flat plate?

We have 9" flat cast-in-place concrete slab with concrete columns. Because the parking garage in the first floor and the basement, the column spacing has to go 29' apart. According to ACI, the minimum slab thickness should be l/30, which is about 12", but client doesn't want to use that much...
