  • Fluid-structure interaction analysis of a reactor subjected to seismic loadings

Seismic Isolation and Seismic Engineering

  • Seismic response analyses of the base-isolated building at Tohoku University (see Multimedia Section below)
  • Structural and seismic analyses of VVER-type reactor structures, systems and components
  • Uplift and rocking of a deformable body subjected to base excitation
  • Vibrational testing and elasto-plastic analysis of piping response under seismic loads

Dynamic Testing

Multimedia

  • Pipe-to-pipe impact analysisPipe-to-pipe impact analysis
    Adaptive finite elements can be used to strategically capture the interaction region between two impacting bodies. Thus the computational power is focused on those parts of the mesh that undergo the most severe deformation.
