Siren 8.0 New Features

  • Siren is a new program which provides the functionality, previously available in GdUte, for predicition of site resposne to a seismic event.
  • Data can be specified quickly through the use of wizards or in tables with options to import data from file.
  • Dockable gateway for quick access to data.
  • Full control over the analysis settings and output.
  • Full range of graphical output options:
    • nodes: displacements, velocities and accelerations (absolute and relative)
    • elements: stress and strain (time histories and hysteresis charts)
    • response spectra: displacements, velocities and accelerations
    • general: interpolation, least squares fit, running RMS, FFT, inverse FFT, filtering, power spectral density
  • Export to Sigraph for further procerssing
