CarolinaADRS

CarolinaADRS is a software with user-friendly graphical user interface for developing site-specific ADRS curves for any location in South Carolina. The theory and software are under development. It is expected to complete by 2025.

CarolinaShake

CarolinaShake is a software with user-friendly graphical user interface for selecting seed time histories from national and local databases and modifying them by matching a target spectrum for use in site response analysis at any location in South Carolina. The theory and software are under development. It is expected to complete by 2024.

TeraUDysac:

• A framework based parallel FE computer program (C++, FORTRAN and Java) for simulating static and dynamic behaviors of unsaturated soils with structural inclusions (pile foundation) in a fully coupled manner.
• Developed during PhD research at the University of Oklahoma, USA.
• Accessible through the internet. Models can be created and run over the internet.
• Three different finite element formulations are derived and implemented for various applications.
  • • Reduced formulation by neglecting both the relative accelerations and velocities of liquid and air phases (u formulation).
      • Can simulate static and dynamic behaviors of partially saturated soils under undrained condition
  • • Partially reduced formulation by neglecting the relative accelerations (relative velocity is taken into consideration) of liquid and air phases (u-p-p formulation)
      • Can simulate static and dynamic behaviors of partially saturated soils under drained and undrained conditions.
  • Complete formulation by taking into consideration of both the relative accelerations and velocities of liquid and air phases.
    • • Displacement formulation (u-u-u formulation)
    • • Mixed formulation (u-u-u-p-p formulation)
    • Can simulate static and dynamic behaviors of partially saturated soils under drained and undrained conditions.
