Concrete Stair Example

[cgstrucg]

Hello,

I need to design a concrete stair with concrete landings at top and bottom. This design is new to me. Can someone please guide me to a proper resource where I can see how to detail the reinforcements for it and also how to check the concrete cross section for the type of reinforcements.

Thanks

Theres some details in the IStructE detailing manual, showing general arrangements/reinforcement drawings and the like.

I am sorry I don't have IStructE access. Are there any codes I can follow to design waist slab and to find out loads supposed to on top of it.

Delegate it to a precast concrete manufacturer.

But, it's really nothing special. Stairs are just sloped continuous or simple span concrete one-way slabs with some extra concrete on top to make the treads:

Loads are going to be per your local building code. Probably 100 PSF live load if I had to guess.
