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).
