Soil behavior complications in different situations lead to a discussion of the need for constitutive models with predictive potential for near-reality behavior in the soil. Soil liquefaction is one of the most complex subjects in the field of Geotechnical engineering. To study the soil liquefaction behavior and effects of this phenomenon on the forces and displacements created in the structure, it is necessary to use appropriate software and constitutive model that can predict soil behavior in different paths. In this research, FLAC 3D software, which is an explicit finite difference program and has the ability to simulate Soil region behavior, has been used and Soil liquefaction behavior has been investigated using Bounding Surface constitutive model. First, the accuracy of the constitutive model has been investigated by using various experiments and then, in order to study the soil liquefaction behavior and its effects on the structure, soil and structure components has been modeled in the form of the existing conditions in reality, and the effect of this phenomenon has been analyzed by changing the loading frequency, the number of structural floors and liquefy layer thickness. In this study, various factors such as excess pore pressure created in different parts of the soil, the pressure imposed along the deep wall, the structure displacements and forces are investigated. Also, the effect of soil different points depth and the point distance from the center of the structure, in the liquefaction behavior of these points, has also been studied. The results indicated that the Bounding Surface constitutive model has the potential to predict soil liquefaction behavior. Studies show that since the onset of liquefaction in the soil to reach a time limitation, this phenomenon acts as an external damping for the structure and reduces the forces generated in structural elements. Also, the change in the thickness of the liquefy layer does not have much effect on the structure forces and displacements, but changes excess pore pressure in different parts of the soil.
