...From the above, it is seen that; the depth of the necessary reinforcing bars in case of bored piles embedded in clay is more or less equal to that recommended by Bowles (1988), and this will be reduced for other cases....
[...]
...Bowles (1988), stated that, for bored piles, the reinforcing bars may be required only in the upper region for moments that are carried by the shaft, because these moments dissipate with depth are hence the shaft load is primarily axial at about L/2. At this depth, temperature changes are not great; therefore, longitudinal and spiral reinforcements are not required. Tomlinson and Woodward (2008), stated that reinforcement is not needed in bored piles unless uplift loads are to be carried (uplift may occur due to the swelling and shrinkage of clays)....

...For this reason, a computer program (PLRN) is modified from that given in Bowles (1988), to check the depth through which the reinforcement will only be required to cover the tension zone of the pile....
