Webof this Modified Hiley Formula in comparison with static load test results for 15 Grade 55C steel H-piles. It will also discuss the results of the correlation studies of pile capacities predicted by CAPWAP and the Modified Hiley Formula for 566 Grade 55C steel H-piles driven by hydraulic hammers at 20 different sites. WebHiley’s formula R=E/ (s+0.5c) is based on the principle of energy conservation in which the energy brought about by hammers during the action of hitting are transferred to piles in ground. When the hammer force and displacement is plotted, the energy absorbed by piles is the area under the curve.
