SMAIAS
Strong Earthquake Analysis And Processing Software
OVERVIEW
Description
SMAIAS, a powerful seismic analysis and processing software developed by Beijing Gangzhen Technology Co., Ltd., serves as an integrated platform for strong-motion data analysis. This system enables real-time processing of seismic data and accelerometer measurements, featuring advanced capabilities including data calibration, computational speed optimization, displacement analysis, peak value extraction, and spectral calculations (including Fourier spectra, power spectra, and response spectra). It also provides comprehensive functionality for intensity calculation. The software supports seamless database integration of intensity calculation results.
Java Runtime Environment Java
▲Hardware: commercial computer (hard disk above 250GB, network card above 100M, memory above 2G).▲ Software: Windows 10 or above.
▲Supports adaptation to domestic operating systems such as Kylin.




Technical Parameter
Waveform data reading
• Supports reading waveform data files recorded by real-time processing system and strong seismometer
• Reads text waveform data files and other waveform data files
Calibrated acceleration recording
• Corrects uncalibrated acceleration recording waveform data for zero baseline and instrument frequency to form calibrated positive acceleration recording
Speed and displacement calculation
• Performs first and second integral calculation of corrected acceleration waveform data to form speed time and displacement time
Response spectrum
• Calculates response spectrum for five damping ratios (0, 0.02, 0.05, 0.1, 0.2) to correct acceleration record
• Calculates threefold reaction spectrum for five damping ratios (0, 0.02, 0.05, 0.1, 0.2)
Acceleration and displacement analysis
• Calculates corrected acceleration record, acceleration, displacement spectrum, and power spectrum of the recording
• Extracts maximum horizontal peak value of corrected acceleration record, maximum vertical peak value, duration of earthquake motion, and dominant period of earthquake
Reference intensity
• Calculates the reference intensity value
Data saving
• Processing results can be saved in various ways: text files, graphic files, and databases
