SeismoSignal v2018 constitutes a simple, yet efficient, package for high-motion data processing. Among other things, it allows for the derivation of elastic and constant ductility inelastic response spectra, computation of Fourier amplitude spectra, filtering of high and low frequency content recorders and estimation of other important seismological parameters, such as Arias Intensity and significant and effective durations.

SeismoSignal also enables filtering of unwanted frequency content of the given signal. Three different digital filter types are available, all capable of carrying out highpass, lowpass, bandpass and bandstop filtering. The program is able to read accelerograms defined in both single- and multiple-values ​​per line format (the two most popular formats used by strong-motion databases), and can apply baseline correction and filtering prior to signal-time integration ( obtain velocity and displacement time-histories).

Here are some key Features of “SeismoSignal v2018” :

  • Elastic and constant-ductility inelastic response spectra
  • Fourier and Power spectra
  • Arias (Ia) and characteristic (Ic) intensities
  • Cumulative Absolute Velocity (CAV) and Specific Energy Density (SED)
  • Root-mean-square (RMS) of acceleration, velocity and displacement
  • Sustained maximum acceleration (SMA) and velocity (SMV)
  • Effective design acceleration (EDA) Acceleration (ASI) and velocity (VSI) spectrum intensity
  • Predominant (Tp) and mean (Tm) periods
  • Husid and energy flux plots
  • Bracketed, uniform, significant and effective durations
