Program AXILTR, AXIal Load-TRansfeR, consists of a main routine and two subroutines. The main routine feeds in the input data, calculates the effective overburden stress, and determines whether the load is axial down-directed, pullout, or if uplift/downdrag forces develop from swelling or consolidating soil. The main routine also prints out the computations. Subroutine BASEL calculates the displacement at the base for given applied down-directed loads at the base. Subroutine SHAFL evaluates the load transferred to and from the shaft for relative displacements between the shaft and soil. An iteration scheme is used to cause the calculated applied loads at the top (butt) to converge within 10 percent of the input load applied at the top of the shaft.
