In this paper, 38 four-pile caps were tested, and the relation between the ultimate strength of four-pile caps and the distance from the periphery of the pile cap to the center of the pile was examined. As the result, it became clear that the ultimate strength of pile caps having thick slab and uniform bar arrangement decrease as the distance becomes shorter. And it became clear that pile caps having short the distance failed in shear before bending yield or after that, even if the calculation predicts flexural failure. The required the distance that the ultimate strength of pile caps having uniform bar arrangement does not lower in comparison with the calculate values seems to be about 1/2 of the pile pitch.
