摘要
This paper presents one-way cyclic tension tests on a pile segment installed in dense sand in a laboratory test setup. The test setup allowed application of surcharges to increase the vertical effective stress. The open-ended pipe pile segment was 0.5 m in diameter and 1 m in length. The test results showed that cyclic loading with small amplitudes can increase the shaft capacity, but increase of the cyclic amplitude can result in large accumulated displacements and decreased cyclic reloading stiffness. The test results are compared to an existing interaction diagram.
