RE: pile driving hammer selection
Minimum hammer energy required is usually noted about 7000 ft-lbs. and the energy for H-pile may be estimate per length as 3*w*L where w is the weight of the pile (lb/ft) and L is the length of pile. Alternately, the energy for H pile may be calculated as a function of bearing value which is 225*bearing value where the bearing value is in tons and hammer energy results in ft-lbs.
Hammer energy is usually listed in the driving equipment charts as standard information. These charts may be obtained from several texts on foundations, including Das, Peck, Hansen & Thornburn, and Bowles.
