Has anyone designed the pre-installed (L-shape/J-shape or) or post-installed (adhesive) concrete anchors with the bent shaft? Like the one shown in the image. Does anyone have the design calculation for this type of anchor that they can share?

As far as I know there is no testing or literature for this type anchor.
My gut tells me it would reduce the capacity of the anchor in tension as you would get high stresses resulting in local concrete crushing at the bend.

The net force on the engaged segment of concrete is still F acting towards the edge regardless of how it is internally resolved by the kinking of the anchor. The segment of concrete engaged will be based on the embedment depth of the anchor, which if anything would be deeper were it straight rather than bent at 30 degrees.I believe the bent anchor has merit. It's true there is a lateral force at the bend point, but the lower end has much better tensile resistance than either a L or J an
