Pile Driving Formulas: Past and Present

Dynamic formulas were in common use in the early part of the 1900s to estimate capacity of a driven pile, and many comparisons were then made with static loading tests. An ASCE Committee was formed in the 1930s to review and make recommendations on the proper use of dynamic formulas; after almost a decade long study, a report was issued in May 1941. The report generated considerable controversy and a remarkable 28 discussions in the Proceedings of the ASCE by several very high profile engineers. Considering the current renewed search by some agencies to find a better dynamic formula, primarily to increase the load and resistance factor design (LRFD) resistance factor to make designs more economical, it is prudent that to revisit this work in order to avoid repeating some of the same mistakes. This review of the extensive discussion comments is presented to better define the problem, and to produce more realistic expectations of what can be achieved by a dynamic formula. The discussions also included to a lesser extent considerations of static loading test procedures and interpretations, which are also discussed in this paper.
