功能：基线调整和滤波、加速度积分、傅立叶谱和能量谱、响应谱等等。
Features
SeismoSignal constitutes an easy and efficient way to process strong-motion da
The elastic and
constant-ductility inelastic response spectra The Fourier and
Power spectra The Arias (Ia) and
characteristic (Ic) intensities The Cumulative
Absolute Velocity (CAV) and Specific Energy Density (SED) The
Root-mean-square (RMS) of acceleration, velocity and
displacement The Sustained
maximum acceleration (SMA) and velocity (SMV) The Effective
design acceleration (EDA) Acceleration (ASI) and velocity (VSI)
spectrum intensity The predominant
(Tp) and mean (Tm) periods The Husid and
energy flux plots The Bracketed,
uniform, significant and effective durations 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 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).
Finally, 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 characteristics plots can be fully customised from within the program itself.
