Site characterization

Site characterization

Seismic design of structures is based on accurate soil and site characterization. The Research Unit of SDG- EE has a long experience in site characterization, including:

  • Geotechnical and geophysical surveys and geotechnical mapping of urban areas at different scales
  • Site-specific ground response and site-amplification studies including liquefaction assessment. 1D, 2D, 3D, linear, equivalent linear and non-linear analyses
  • Proposal of improved soil amplification factors for the soil classes of Eurocode 8
  • Proposal of a more detailed and elaborate soil classification system (new CS) and corresponding elastic response spectra for Eurocode 8 (EC8)
