About this Course

Spectral Matching

  • Selection, access, and Importing accelerogram in AT2 and SMC formats.
  • Matching to user-defined target spectrum.
  • Matching to USH from an EZ-FRISK™ seismic hazard analysis.
  • Scoring of accelerograms for suitability for matching based on magnitude, distance, duration, scaling required, and initial spectral response shape.
  • Initial vs. matched time histories for acceleration, velocity, and displacement.
  • Export of matched accelerograms in a format suitable for site response analysis with Shake91 and AT2 format
  • Export of ground motion time histories using spectral velocities and displacements.
