Numerical Modeling


GEC provides advanced numerical modeling services to perform soil structure interaction (SSI) analysis. This allows us to fully incorporate geometric and material non-linearities into our models, which results in better understanding of the structural behavior. This approach leads to more cost effective designs through optimization when compared to more simplified rigid body and limit equilibrium methods.


GEC is uses the following software:


  • FLAC
  • FLAC 3D
  • Plaxis
  • SAP2000
