SeismoSignal – Earthquake Software for Signal Processing of Strong-Motion data
SeismoSignal constitutes an easy and efficient way to process strong-motion data, featuring a user-friendly visual interface and being capable of deriving a number of strong-motion parameters often required by engineer seismologists and earthquake engineers. SeismoSignal opens an accelerogram from text files in different formats.
SeismoSignal Features
- Units for both the metric and the imperial system are supported
- Baseline Correction and Filtering
- Velocity & Displacement time-histories
- Fourier and Power Spectra
- Elastic and inelastic acceleration, velocity and displacement response spectra
- Overdamped elastic spectra
- Constant-ductility inelastic spectra
- Calculation of several ground motions parameters:
- Peak ground values of acceleration (PGA), velocity (PGV) and displacement (PGD)
- Root-mean-square (RMS) of acceleration, velocity and displacement,
- Arias Intensity (Ia)
- Characteristic Intensity (Ic)
- Specific Energy Density (SED)
- Cumulative Absolute Velocity (CAV)
- Acceleration (ASI) and Velocity (VSI) Spectrum Intensity
- Housner Intensity (HI)
- Sustained maximum acceleration (SMA) and velocity (SMV)
- Effective Design Acceleration (EDA)
- Predominant Period
- Husid plot
- Energy Flux plot
- Four different types of record durations are computed: (i) the Bracketed duration (ii) the Uniform duration (iii) the Significant duration and (iv) the Effective duration.
- Data and results presented in tables or charts and easily exported to other Windows application (e.g. MS Word and MS Excel).
