Output:

    Definitions
    • ϕb = Resistance factor for bearing
    • fc = Specified concrete strength (psi)
    • A1 = Area directly loaded in bearing (in2)
    • A2 = Area of the lower base of a frustrum, pyramid, cone, or tapered wedge contained wholly within the bearing support and having its upper base equal to A1. The sides of the cone slope 1V:2H (in2)
