In order to improve the deformability of PHC piles, we proposed the details of new connecting method between the pile and the pile cap in Part 4. Some new experiments and analyses have been carried out to examine the effect of the buried depth of pile into the pile cap and the amount of longitudinal bars arranged in the pile and the hollow part of it for the ultimate bending strength of PHC pile structure under low axial loads. We took the following result. 1). The deformability of PHC pile with large buried depth becomes smaller than that with small one. 2) The ultimate bending strength and the deformability of PHC pile becomes better when circumference of longitudinal bars of pile is increased. 3) We can calculate the ultimate bending strength of PHC piles by the method shown in this paper.
