CAPWAP uses force and velocity data measured on a foundation impacted by a ram to determine:

Static shaft resistance, magnitude and distribution
Static end bearing
Stresses at any point along the shaft
Energy transferred from the ram to the foundation

Measurements are made with a Pile Driving Analyzer. CAPWAP simulates a static load test and predicts the instantaneous load settlement behavior of the tested foundation.

CAPWAP 2006 has improved help functions and features that enhance the analysis of drilled shafts and auger cast-in-place piles.
