SeismoSignal, SeismoSpect, SeismoMatch amd SeismoArtif |
|
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. 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. 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. |
