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.Bracketed, uniform, significant and effective durations.Average spectral acceleration (Sa, avg).SEISMOSIGNAL is an interesting, user-friendly and efficient commercial software for processing of strong motion data 15. SeismoSignal also enables the filtering of unwanted frequency content of the given signal. Three different digital filter types are available, all of which capable of carrying out, causal or acausal, highpass, lowpass, bandpass and bandstop filtering. ![]() The program is able to read accelerograms defined in both single- and multiple-values per line formats (the two most popular formats used by strong-motion databases), and can apply baseline correction and filtering prior to time-integration of the signal (to obtain velocity and displacement time-histories).įinally, and due to its full integration with the Windows environment, SeismoSignal 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.
