concrete arch design

[samdamon]

I am seeking design guidance for an unusual cast-in-place arch. Its more like half an arch, actually, perhaps better called a haunched cantilever, if that makes any sense. The left support is high, right support is low. The cantilevered potion of the arch extends to the right and ends about 15' away from right support. At the far right end of the arch the section needs to be its shortest in height.

Many precasters seem to make "spandrel" arches to finish off the sides of a bridge or culvert, usually in two pieces. But my geometry and loads are a little unusual, and I don't think an "off the shelf" 1/2 spandrel panel is going to work for me.

Anyone know of any articles or texts that might be useful?
Classic arch design approaches do not seem appropriate, and Web search so far has been fruitless.

I am not sure that I understand the geometry but why call it an arch and not design it like a normal moment frame? Just a curve will not make anything a classical arch.

Ciao.
