Abstract
The design of precast piling is somewhat unique in structural engineering, as the pile is required to satisfy a number of only semi-related conditions, which are:
1. Total and nature of load to be carried.
2. Foundation conditions.
3. Handling of pile prior to driving.
4. Driving conditions of:
(a) Different strata to be driven through;
(b) Design load required;
(c) Driving equipment, tolerances, site control and head packing.
The inherent variability of the soil, driving equipment and head packing, and the actual concrete strengths have made factual analysis of pile stresses and carrying capacities exceedingly difficult. Because of this, with the advent of a new type of pile, the tendency has been to develop empirical rules of design, of load capacity and of determining driving conditions.
