Self supporting staircase
Self supporting staircase
(OP)
Hey guys, a good costumer of me call me and ask if I can design a self supporting helicoidal staircase, I have no clue how to handle this , do you guys have some literature to refer to me about that topic?

Just write ' HELICAL STEEL STAIR ' and search the web..two of the outcomes ..
This is a specialized plate work ..

My suggestion would be , search for local manufacturer ..

Like a general practitioner sending you to a cardiologist. They know what the heart is, generally what to do to keep it healthy, and they know when something's wrong, but a cardiologist knows how to fix it.
You're the general practitioner who can design a stair when he needs to...the cardiologist is the guy who designs three custom stair cases per day.
That's not to say you can't do it...but there are plenty of issues, particularly with steel stairs. I could see vibration being a bit of a challenge in something like that. Start with the AISC design guide on steel stair design. Other than that, you'll need FEM as dik mentioned and you'll need to dust off some numerical methods to evaluate the shape and check your model.

ASCE 7 might require a horizontal slip connection for seismic. Be sure to check that out.
