Abstract
The pseudo-dynamic test method in centrifugal field is proposed. To clarify the effectiveness of the test method, shaking table tests are also conducted. As the result, the proposed pseudo-dynamic test can simulate seismic response considering the inertia dynamic interaction between the soil and the superstructure. The results of pseudo-dynamic test, including the displacement response and the deformation of piles, are good agreement with that of shaking table test. Assuming that hysteretic model of the structure is a nonlinear steel column, it can evaluate the effects of the nonlinear superstructure. In addition, the centrifuge similitude is the same as that of the pseudo-dynamic test. Therefore, the pseudo-dynamic test is a powerful tool for soil-structure interaction.
