I have a question regarding kinked stringer design. The NAAMM standard for metal stairs design kinked steel stringers based on a uniform load that is projected along the length of the stringer. When I look at a kinked steel stringer it appears that there would be an outward thrust at each end of the steel stringer.
What would be the correct way to design a kinked steel stringer? Is there an industry standard regarding designing for the thrust?
Thank You, Val
