Cantilevered concrete deck with radius
Cantilevered concrete deck with radius
(OP)
I am designing a 6" concrete deck that will have about a 5' cantilevered radius portion (picture a half-circle cantilever). I am trying to come up with an efficient design and not get carried away with reinforcement. Putting in rebar that follows the radius looks good on paper, but is not very effective at design. A series of varying length bars seems to work better for design, but then I have curved sections without reinforcment at the ends. Maybe a combination of the two is best.
Any recommendations?

In the opposite direction you would only have temp & shrinkage reinforcement. The bars could run perpendicular to the main bars.
I would add extra radiused bars at the edge of the deck just to try everything together, and to help with anchorage of any handrails, etc.

Check that the 45 degree resultant of the two bars is enough at the 45 degree mark and then you are okay for strength.
Circumferential bars are a must top and bottom along the outside edge.
Radiused bars are a pain, and IMO never get done right.
