However, current structural seismic design generally neglects the influence of the subsoil. Design codes that deal with liquefaction usually focus the settlements that can affect the structural foundations. Additionally, most studies related to soil-structure interaction have focused on the response of an isolated structure. In reality, especially in urban areas, this assumption rarely can be justified. The omission of adjacent structures can lead to inaccurate results, especially when nonlinear behaviour of soil, e.g. resulting from liquefaction, takes place. The aim of this work was to implement a holistic approach to the study of liquefaction. The influence of an existing structure on the liquefaction potential will be presented. Also, the effects of adjacent structures on the seismic response will be investigated under conditions of liquefaction. To reach those goals, a series of physical experiments were performed in the centrifuge facilities of the Japanese Institute of Occupational Healthy and Safety (JNIOSH) in Tokyo. A laminar box was used to reduce boundary effects. Rigid blocks were used to represent the influence of a shallow foundation on the underlying soil. In order to achieve a homogeneous density, the sand was rained from a fixed height above the base of the box. Preliminary results show a higher settlement for a stand-alone structure compare with free-field condition. It was found that an adjacent structure had a significant influence of the response of the foundation soil
