Abstract

In liquefied soil during earthquake, steel piles beneath building structures may buckle issued from the large compressive load such as dead load, live load and out of overturning moment. In our previous papers, the centrifuge tests of frames with circular tube piles and liquefied soil, has been performed to clarify the piles' dynamic buckling behavior subjected to only compressive force. In this paper, the centrifuge test is applied for the dynamic behavior of small scaled models subjected to vertical and horizontal forces, and the piles' dynamic collapse mechanism in liquefied soil is described, and piles' strength is estimated by the M-N interaction curves.
