| Research Abstract |
To investigate the response of base-isolated structures and pile's stress, dynamic centrifuge tests and numerical analysis were performed. The seismic response of the footing supported by the high rigidity piles was more similar to the input motion than that of the footing supported by the low rigidity pies. Therefore, the high rigidity pile reduced the superstructure acceleration amplitude and the shear deformation of the seismic isolator, when the predominant period of the soil was close to the natural period of the superstructure.
