Abstract
This study evaluated an uplift behavior of circular and square anchor foundations in dense Toyoura sand, by comparing a model test with 3D FE analysis. The model tests were performed by taking the value of h/D as two. The 3D analysis was an elasto-plastic model in which progressive failure with shear band effect was introduced into the constitutive equation. The 3D analysis was able to predict the uplift behavior in both circular and square anchor foundations. The uplift resistance in circular anchor foundation was smaller than in square anchor foundation in case of having same D. The scale effect was recognized and the degree of the scale effect was similar in both anchor foundations.
