poured concrete elliptical arch
poured concrete elliptical arch
(OP)
Is rebar needed for a poured concrete elliptical arch having an aspect ratio of two to one? The crown of the arch would be 4" thick to support a pathway. The end of the arch would be supported by an 18" poured concrete retaining wall backed by soil. The major diameter would be about 12' long and minor axis half of that. assume loading at 100lbs per linear ft. Width of arch not yet determine but base you comments on a per width of ft.

No problem w/ 6" of concrete at the crown of the arch.
I dont want to cut oval RCP in half as it seems like a waste of good material.
Should the reinforcement conform to the shape of the elliptical arch / let's say 2" of concrete conver over the rebar. Also should I provide rebar 2" below the surface of the pathway supported by the arch?
