Abstract
Non-linear interaction between the soil and foundations is one of the means to affect the seismic responses of structure. Focusing on the ductility of the fibers and the elasticity of rubber-chips, authors have developed an artificial geo-material, which is stable up to a high strain region, by mixing cement, rubber-chips from scrap tires, and fibrous materials. This paper discusses the shear mechanism and the properties of the compound based on laboratory studies. Authors also expect that this compound would effect on reducing the environment load since it is made of scrap tires and waste soil generated in construction sites.
