Vehicular Railing Load
Vehicular Railing Load
(OP)
I'm trying to design a 42" tall concrete rail that sits on top of a gravity modular block wall. I understand that there is a 10 kip design impact load at the top of the rail but I don't understand how that load is distributed. AASHTO says that it is distributed along the length of 0.8X+3.75', but X is for post spacing and not applicable since the railing is continuous concrete. Is it practical to take this 10 kip load into a klf load? If so, how?

I have a little background in bridge design. Consequently, I have looked at concrete rails such as the one you are describing as being similar to bridge rails. The LRFD design manual Table A13.2-1 gives a force and a width to apply the force based on test level. The lowest design level is 13.5kip over a 4' longitudinal width.
Am I talking about a completely different topic?
