A direct time-domain procedure for the seismic analysis of dam–foundation–reservoir systems using the scaled boundary finite element method

Influences on the Seismic Response of a Gravity Dam with Different Foundation and Reservoir Modeling Assumptions

“…The radiation damping of an infinite foundation is an important factor affecting the structure-foundation interaction, which can be simulated by setting artificial boundary conditions at the foundation truncation. Various artificial boundaries have been proposed to date, such as viscous boundary [10,11], viscous-spring boundary [12,13], scaled boundary finite element method [14,15], infinite elements [7,16], and perfectly matched layers [17]. Hariri-Ardebili and Saouma [18] investigated the effect of different foundation numerical models and corresponding boundary conditions on the seismic responses of arch dam-foundation systems under near-fault and far-field ground motions.…”

Time-domain analysis for the scattering of plane elastic waves in half-space with an open trench

“…The equivalent nodal forces resulting from the free-field motion can be determined from the shape function and the unit surface traction (Bazyar and Song, 2017;Huang et al, 2017;Qu et al, 2021).…”

“…The scaled boundary finite element method (SBFEM) is a numerical method developed gradually in the course of simulation studies of elastic dynamics problems in infinite domains (Song, 2018;Wolf, 2003), which has the advantages of semi-analytical, high accuracy, reduced dimensional solution, and mesh flexibility. At present, the SBFEM has many applications to the problem of elastic wave scattering in half-space (Bazyar and Song, 2017;Chen et al, 2015b;Qu et al, 2021). Based on the theory of soil-structure interaction, the site with an open trench is decomposed into a near-field system and an infinite far-field system.…”
