A 35° cone from the anchor head to the concrete surface. The projected area determines the capacity.

Distance from concrete surface to the bearing surface of the anchor (head or nut).

Capacity is proportional to √fc. Doubling fc increases capacity by ~41%.

Reduced edge distance requires capacity reduction factors per ACI 318.

Cast-in anchors use kc=24. Post-installed may use kc=17 depending on type and approval.
