SeismoSignal 4.0

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 calculates 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.
