DESCRIPTION:Calibration\, on the basis of data from centrifuge and shake t
 able experiments\, continues to promote the development of more accurate c
 omputational models. Capabilities such as coupled solid–fluid formulatio
 ns and nonlinear incremental-plasticity approaches allow for more realisti
 c representations of the involved static and dynamic/seismic responses. In
  addition\, contemporary high-performance parallel computing environments 
 are permitting new insights\, gained from analyses of entire ground-founda
 tion-structural systems. On this basis\, the horizon is expanding for larg
 e-scale numerical simulations to further contribute toward the evolution o
 f more accurate analysis and design strategies. The presentation addresses
  these issues through recently conducted three-dimensional (3D) representa
 tive research efforts that simulate the seismic response of: (1) shallow-f
 oundation liquefaction countermeasures\, (2) pile-supported wharf systems\
 , and (3) a full bridge-ground systems. A discussion of enabling tools for
  routine usage of such 3D simulation environments is also presented\, as a
 n important element in support of wider adoption and practical application
 s. In this regard\, graphical user interfaces and visualization approaches
  can play a critical role.
