Concrete staircase questions 5

[mats12]

HI!

I would like to design this staircase, but have some issues/question about modeling:
Is it okay to support RC landing on RC beam/corbel that is anchored to the concrete wall as shown or is there a better way to design this?
Also can I use bottom (1st) stringer to support landing? Everything is a new structure, including the wall.

It seems possible, but there are a lot of pieces to design. Such is the nature of structural engineering.

The arrangement is way out of the realm where you can just cartoon something on the drawing and the builder will make it work.

I think what you have protruding from the wall is a concrete beam, not a corbel.

Will your mid level landing have an attachment to the wall? If so, you it appears to me that you have some ways of simplifying the design before considering all of the details.

JLNJ stated loudly and clearly. I'll provide a beam and post at stringer-landing interface.

There is a natural, and very common way to handle this situation if your architect will permit you a little flexibility.

From a real life project that I worked on.

I would just cantilever the landing out and span the flight between landing and ground.

Thank you all for helping me out.

Especially Kootk and slickdeals. Big thanks!
