Abstract

In the previous papers, when slender steel piles beneath buildings experience high axial compression forces as a result of vertical loads increased by P-Δ effects with inertia forces acting on the buildings and then the soil liquefies, buckling of the piles occurred even though they are restrained laterally by the liquefied soil. In the real structures, the pile is subjected to the lateral and axial force during earthquake. This paper estimates the ultimate strength of slender piles in liquefied soil when steel pile subjected to vertical and horizontal load. The relationship between the axial force and the flexural moment of the slender piles and the soil-pile interaction is presented.
