Dear member,
As far as I know about spiral staircase it is designed as BEAM @ centre and CANTILEVER on both edges (Throughout the Length)
or
2 BEAMS on edges throughout the complete length (Complete Spiral length)
with simple assumptions as taken in any stair design..
this is simple version of design and for all others CHECKS you should refer some books
NADIM HASSOUN, MARK FINTEL may have some calculations of this stair design (SEE THREADS)
Let me know if you have any problem (or if I am wrong) =)
Regards,
Umer Aleem
