Axial Pile Capacity Calculator

Alpha (API RP 2A), Beta (Burland) and Lambda (Vijayvergiya & Focht) methods for ultimate shaft friction and end-bearing capacity in layered soil profiles.

Calculates the ultimate axial capacity of driven piles or drilled shafts using static analysis methods (Alpha, Beta, and Lambda). Assumes consistent SI units (kN, m, kPa).
