Abstract:

This report contains the results of a study describing the development of resistance factors for use

with the Kansas Department of Transportation (KDOT) Engineering News Record (ENR) formula for driven

piles. KDOT has verified driven pile resistance for many years using a version of the ENR formula. This

formula yields estimates of nominal resistance values that are much lower than the actual resistance, based

on department experience and comparisons with other resistance measurement methods. For this study actual

ENR resistance estimates were compared with estimates obtained using a pile driving analyzer (PDA)

system. The PDA values were taken as the true capacity. There were 175 end-of-drive data points and 189

restrike data points available for statistical analysis. A set of correction (resistance) factors to be used with

the ENR formula was developed, with individual factors based on given probabilities of pile failure (capacity

being exceeded).
