Arched Concrete Beam
Arched Concrete Beam
(OP)
Does anyone know how to design a CIP concrete beam that is arched at the bottom?
If the bottom steel is made to follow the shape of the arch (seems logical), and the bottom bars are in tension, the reinforcing would try to straighten. The ties would be the only thing keeping the bars from popping out of the bottom of the beam. What am I missing here? What is the proper reinforcing layout for this situation?

It all depends on the geometry and the support conditions, as others have said. But if it is a simple span, I would tend to make the main bottom bars straight, with smaller supplemental bars following the curve.
