Influence of Liquefaction and Adjacent Structures on Seismic Response (original) (raw)

During past decades the destructive potential and the complexity of soil liquefaction phenomenon associated with strong earthquakes has been widely documented. 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 co...
