56 It was then decided to study the old methods under three circumstances, first, for piles with Davisson capacity less than 1779 kN, second, for pile with capacity larger than 1779 kN, and finally for the all cases. Based solely on the statistical analysis and the lognormal probability distribution, the assessment of the eight dynamic methods to determine pile capacity could not be successfully completed (i.e. no criterion). The LRFD resistance factor was then recommended to assess the performance of each method. In the next section, a description of the LRFD results is presented.
