I am trying to figure out how to attach a 42" pony wall around the edge of an elevated floor and connect it to the floor in a way that it meets the 200 lb point load requirement in the IBC on guardrails. If I use 200 lb applied at 42" height, I get a moment at the base of 8400 in-lb. Using a 2x4 wall, if I try to just lag this wall down, I can't get the numbers to work at for any reasonable connection. Even assuming a put a strap or L-bracket on the outside faces of the wall, that only gives me 3.5" of moment arm for resisting the overturning, which means the restraint will have to be 2400 lb. How do these get built? Does anyone have any suggestions?
