Steel pipe piles with wings have been developed and used in middle-and low-rise buildings. A steel pipe pile with wings is installed by applying a rotational torque to the pile shaft. However, the wings that have a larger diameter than the pile shaft loosen the soil around the pile shaft, causing reduction of lateral resistance of the pile. In this study, we investigated the effect of reinforcement for the soil around the pile head on lateral resistance of the pile.
