3-Dimensional Transmitting Boundary for Dynamic Soil-Structure Interaction Analysis in Water-Saturated Transversely Isotropic Stratum

동적 지반-구조물 상호작용 해석을 위한 지하수로 포화된 가로등방성 층상지반의 3차원 전달경계

If a structure is founded on the ground saturated with pore water, then the ground should be modeled as a saturated two-phase porous medium for accurate earthquake response analysis. In this study, a 3-dimensional transmitting boundary is developed for modeling of far field using u-U formulation for water-saturated transversely isotropic layered stratum. The developed transmitting boundary is verified by comparing the dynamic stiffness of rigid square foundation on water-saturated isotropic layered stratum with the case of using equivalent single-phase medium model.
