In this paper, centrifugal tests of a superstructure with high height-to-width aspect ratio, steel piles, and the liquefied soil system are presented to clarify piles’ collapse mechanism. It is presented that additional shear force generated by pile’s P-' effect accounts for the largest part of pile’s ultimate shear force. It is also shown that piles’ horizontal load bearing capacity can be evaluated easily using piles’ horizontal strength based on pile’s plastic bending strength, to which pile’s elasto-plastic flexural buckling strength is applied, reduced by initial axial force and the location of the inflection point in the liquefied soil.
