Diaphragm - Plain Concrete

[Samwise Gamgee]

Can a composite / rigid diaphragm be designed as unreinforced beam. As the diaphragm is a beam with significant depth (150' in my case) , can I just check for cracking stress and avoid adding any rebar or chord members ? Mc/I is significantly less than cracking strength of concrete

I’d like to see the shear studs extend up beyond the mesh. That’s a requirement in my part of the world.

Since you’re showing mesh, then (again.. in my corner of the earth) you’re allowed to consider the mesh within the first 1200mm width of slab acting as your peripheral tie steel - which in turn acts as your tension steel for the diaphragm.

I believe you can still accomplish a continuous edge angle even with the interruptions at the columns. It's just a matter of detailing.

Yes, I will detail it to be a continuous angle.
