A new method of base isolation against earthquake damage using natural material

Abstract In this paper, the idea, construction and experiment study of a new isolation method using soil liquefaction is presented. Reports about earthquake hazards and research work in laboratories have indicated that liquefied soil can be used as an isolation material, when some prerequisites are fulfilled. After an experimental study of the soil material, a model of this isolation system was tested on a shaking table. The results show an effective isolation of this method. The motivation of studying this method is to obtain an economical isolation system.
