The use of finite element method in soil-structure interaction analysis dictates that the infinite soil medium be truncated along a certain boundary, called artificial boundary, separating the soil-structure system into near and far fields. In conjunction with the analysis of near field, some artificial boundaries capable of transmitting waves from near to far field are proposed in literature. In the present study, first these artificial boundary conditions are reviewed, and then they are assessed by using some chosen sample problems. The comparisons are presented in both time and frequency spaces. |
