The instrumentation comprised vibrating wire strain gages at 1.0, 5.8, 9.4, and 12.0 m depth. The pile stiffness (EA) was determined by the secant and tangent methods and used in back-calculating the distributions of axial load in the pile. A t-z/q-z simulation of the test was fitted to the load-movement distributions of the pile head, gage levels, and pile toe. The load-movement response for the shaft resistance was strain-hardening. The records indicated presence of residual force. Correction for the residual force gave a more reasonable shaft resistance distribution and indicated an about 600 kN residual toe force.",
