Dynamic Behavior of Rigid Circular Foundation in Water-Saturated Transversely Isotropic Layered Stratum

지하수로 포화된 가로등방성 층상지반에 설치된 강체 원형 기초의 동적 거동

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, an axisymmetric transmitting boundary hyperelement is developed for modeling of far field of the ground using u-U formulation for water-saturated transversely isotropic layered stratum. The developed hyperelement is verified by comparing the dynamic stiffness of rigid circular foundation on water-saturated isotropic layered stratum with the case of using equivalent single-phase medium model.
