Abstract : This paper discusses methods that were developed in the period 1955-1957 in the analysis of wave force measurements on a 30-inch diameter test pile in a water depth of 40 ft. in the Gulf of Mexico. Procedures for reducing the raw data to a form suitable for digital computer operations are outlined. Measurements of wave elevation eta (t) at the pile, obtained by motion picture camera, were successfully checked with measurements of vertical reaction R sub z (t) on the double-hinged pile, suitably adjusted by a numerical frequency response operator technique. Numerical filter techniques were used to erase unwanted vibrational frequencies from the records and frequency response operators used also to derive horizontal velocity and acceleration components (at the level of action of total force) from the records of eta (t).
