The stair is 6'-6" wide with outside radius of 13'-6" and inside radius
7'-0". The stringers are made from C12 and the risers and treads are 12ga
closed system welded to the stringers.
The arc is 90 deg.
Are there design charts or tables that have already been prepared for stairs
of this type? If not, are there shortcuts to design other than doing a
finite element anaylsis.
I'm doing the structural design.
Thank you for your assistance.
