Abstract

This paper investigated the dynamic buckling behavior of reinforced concrete (RC) pile using a cenlrifuge model. Three specimens with soil densities and input waves as variables were tested by uni-axial shaking. Buckling failure occurred in the pile members of all centrifugal models after the ground were liquefied. All pile members formed Hiree plastic hinges at the pile head, lower side, and middle position. The measured buckling slrength of the RC pile model of the centrifuge model was evaluated by extending the tangent modulus theory.
