SeismoSignal, SeismoSpect, SeismoMatch amd SeismoArtif 
constitute a suite of programs that are used to carry out basic earthquake records, such as the processing of strong-motion data, the derivation of elastic & inelastic response spectra and Power & Fourier spectra, the calculation of a number of commonly used ground
motion parameters, the adjustment of earthquake records to match a specific target response spectrum, or the generation of artificial earthquake accelerograms.

 


 

SeismoSignal

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 opens an accelerogram from text files in different formats.

SeismoSpect

from text files in different formats, to create their own library of ground motion records and save them all in a single file making it easy to handle and share large numbers of records.
It features a user-friendly visual interface and is capable of deriving a number of strong-motion parameters often required by engineer seismologists and earthquake engineers.

 SeismoMatch

adjusting earthquake records, through wavelet addition, to match a specific target response spectrum. Users have the opportunity to simultaneously match a number of accelerograms, and then obtain a mean matched spectrum whose maximum misfit respects a pre-defined tolerance.
This software can thus be used in combination with records selection tools and records appropriateness verification algorithms to define adequate suites of records for nonlinear dynamic analysis of new or existing structures.

SeismoArtif

generating artificial earthquake accelerograms matched to a specific target response spectrum using different calculation methods and varied assumptions. It is noted that the use of real accelerograms and spectrum matching techniques (i.e. SeismoMatch), together with records selection tools, tends to be recommended for the derivation of suites of records for use in nonlinear dynamic analysis of structures. However, in those cases where access to real accelerograms is, for whatever reason, challenging or inappropriate, then a tool such as SeismoArtif will be of pertinence and usefulness.
