Signal Processing for Ground Motion Records

SeismoSpect constitutes a simple and efficient platform for signal processing that allows to create a personal library of ground motion records and save them all in a single file making it easy to handle and share large numbers of records.

SeismoSpect features a friendly graphical user interface capable of reading accelerograms saved in different text file formats (Single-value per line, Time & Acceleration values per line, Multiple-values per line, SMC format, PEER NGA format and Shake (.eq) format).

  • Maximum acceleration, velocity and displacement

  • Overdamped and constant-ductility inelastic response spectra

  • Arias Intensity (Ia)

  • Cumulative absolute velocity (CAV) and specific energy density (SED)

  • Housner Intensity

  • Predominant (Tp)

  • Number of effective cycles

  • Maximum incremental velocity (MIV)

  • Average spectral acceleration (Sa,avg)

  • Effective design acceleration (EDA)

  • Root-mean-square (RMS) of acceleration, velocity and displacement

  • Characteristic Intensity (Ic)

  • Acceleration (ASI) and velocity (VSI) spectrum intensity

  • Sustained maximum acceleration (SMA) and velocity (SMV)

  • Significant duration

  • Damage index

  • Impulsivity index (IP Index)

Completely visual interface. No input or configuration files, programming scripts or any other time-consuming and complex text editing requirements.

Due to its full integration with the Windows environment, SeismoSpect allows for numerical and graphical results to be copied to any Windows application (e.g. MS Excel, MS Word, etc.), noting that the plots characteristics can be fully customised from within the program itself.
