Efficient and accurate domain-truncation techniques for seismic soil-structure interaction

摘要: We modify the formulation of a recently developed absorbing boundary condition (ABC), perfectly matched discrete layers (PMDL), to incorporate excitation coming from exterior such as earthquake waves. The modified indicates that effect can be incorporated into PMDL ABCs (traditionally designed treat only interior excitation) simply by applying appropriate forces on nodes connected first layer. Numerical results are presented clearly illustrate effectiveness proposed method.
