SeismoSignal是功能強大的強運動數據的信號處理解決方案,使用將為用戶提供最簡單有效的強運動數據處理方法,並且界面超級的簡單友好,您可以讀取不同文本格式的加速度圖,支持對其進行過濾和基線校正,完全可視化的界面。沒有輸入或配置文件,編程腳本或任何其他耗時且複雜的文本編輯要求。於它與Windows環境完全集成,SeismoSignal允許將數字和圖形結果複製到任何Windows應用程序(例如MS Excel,MS Word等),並指出可以從程序本身內完全自定義繪圖特徵。並且能夠獲得工程師地震學家和地震工程師經常需要的大量強運動參數,SeismoSignal 2018西你版本支持SHAKE軟件輸出的.eq文件,用於打開加速度圖。在“地面運動參數”模塊中引入了有效循環數,損傷指數,IP指數,平均光譜加速度和最大增量速度。

SeismoSignal constitutes a simple, yet efficient, package for the processing of strong-motion data. Amongst other things, it allows for the derivation of elastic and constant ductility inelastic response spectra, computation of Fourier amplitude spectra, filtering of high and low frequency record content and estimation of other important seismological parameters, such as the Arias Intensity and the significant and effective durations.

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

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).
