New construction per 2010 CBC.
Required exit width of 68" for steel stairs.
Some conclusions -
a) It is generally accepted that this exit width would be the clear width between stringers.
b) With a 68" req'd exit width, we would have to provide an intermediate handrail.
c) If we were to project the handrails 4" (4.5" max), we would not need to provide intermediate handrail.
d) With a 3" Stringer along the wall, the handrail would need to project 7" from the wall to avoid int.handrail.
Does this make sense or did I skip any steps/misinterpret anything?
Also, if I DO provide an intermediate handrail, would I need to extend the entire landing an additional (11"+12") 23" to provide adequate exit radius?
Thank you!
