Design Method of Structure Considering Liquefaction and Subsequent Lateral Flow

Ryo SAWADA, Akihiko NISHIMURA


  In this paper, the authors focus on the method of designing structures against liquefaction and a subsequent lateral flow. Shaking table tests and analyses were carried out to clarify the mechanism of pile stresses caused by the liquefaction-induced lateral flow. As a result, it is clear that design of structure against liquefaction shell reflect changes in the natural frequency considering additional inertia force of liquefaction ground. Also it has become possible to economically design structures by assuming that the liquefaction-induced lateral flow is a ground displacement force.
