ACS SASSI NQA V4 Advances for Seismic SSI Analysis of NPP Structures


  • Present a top-level overview the new ACS SASSI NQA V4 software capabilities in the light of the new US practice trends
    including ASCE 4-16 and 43-19.
  • The ACS SASSI V4 (IKTR0) computational speed of the SSI analysis is about 2-3 times faster than the latest ACS SASS
    NQA V3 (IKTR10) software.
  • Depending on the SSI problem size and the MS Windows PC workstation available resources, the SSI analysis runtime
    speed of the new 2019 version can go up to 5 times faster than the current 2018 version.


New features include:

- New Fourier zero-padding (FZP) interpolation acceleration time histories. Required for high-frequency. Modification in EQUAKE.

- Improvements on the fast-post processing options. Modification in MOTION, RELDISP and STRESS.

- New FE type called HVD (3D High Viscous Damper) for seismic base-isolation problems. Modification in HOUSE.

- New Option 2DSOIL for nonhorizontal soil layering. Developed a new NST Module.

- New UI commands to support new functionalities; HVD, Binary Options for MOTION, RELDISP, STRESS, new 2DSOIL option.
