Dimensional analysis was applied to derive an analytical model of the axial bearing capacity of drilled piers. The solution based on the limit state of deformation, defines the ultimate load-settlement curve as a combination of a parabola and a straight line. The parabola is defined by the settlement at ultimate yield load. The settlement is computed using the cumulative modulus. Back-calculated values of cumulative moduli are given. The capacity reduction factor 0. 7, introduced in analysis of ultimate shaft resistance and of ultimate bearing capacity is suggested, being adequate to a confidence level 0. 95. Refs.
