Title: UBC 97 Anchorage to Concrete
I am getting a difference in opinion on the calculation of Ap in UBC 97 Section 1923 Anchorage to Concrete and would like the list's opinion. For discussion sake, assume a 24"x24" block of concrete in plan with an anchor bolt located 3 inches from the south and west edges and embedded 12 inches. Is the area Ap equal to a circle with a 3 inch radius (corresponding to 3 inch edge distance)? or is it equal to the overlapping area of a 12 in. diameter circle and the block of concrete (a circle with two sides cut off)? I personally believe it is the latter, as it represents a more realistic pullout cone.
