Soil Dynamics & SSI

Grid Engineers have a solid background in soil dynamics and foundation engineering. Our design is powered by 2D and 3D simulation capabilities that incorporate advanced soil and structural constitutive models and may address profoundly non-linear issues such as soil-foundation separation/slippage. Our consulting services include:

  • Microzonation mapping of ground motion characteristics: detailed maps with maximum acceleration, velocity and displacements (PHGA, PGVA, PHGV and PGD)
  • Evaluation of topography effects on earthquake ground motion
  • Beam-on-nonlinear-Winkler-foundation models
  • Dynamic impedances for surface and piled foundations
  • Assessment of Liquefaction Potential of soils
  • Liquefaction Risk Assessment and Design of Foundations
