Ultimate strength and deformability of the footing connections of steel pipe piles embedded in footing concrete have been examined by adopting peripheral reinforcing bars such as ring bars, spiral bars, and vertical bars. It is shown that the connections can develop preferable behavior when peripheral bars are disposed adequately together with main bars. Based on the experimental results, failure modes of the connections are introduced inclusively and empirical formulas for the ultimate strength are derived, which may enable a more rational earthquake resistant design of pile foundations.
