 ABSTRACT

series of 1-g shaking table tests. The experimental results show that the stone column can prevent large shear deformations such as cyclic softening in clayey deposits. However, it is also shown that the surface acceleration in improved clayey deposits may be amplified more than that in unimproved clayey deposits when subjected to short periodic seismic motions.

Keywords: Seismic behavior, Shaking table, Site response, Stone column
