Earthquake Software for Response Spectrum Matching
SeismoMatch is an application capable of adjusting earthquake accelerograms to match a specific target response spectrum, using the wavelets algorithm proposed by Abrahamson  and Hancock et al.  or the algorithm proposed by Al Atik and Abrahamson . After loading some accelerograms and defining the target response spectrum, users need only to define the spectral matching algorithm, adjust the spectral matching period range, set the required tolerance and the spectral matching is executed.
SeismoMatch also features a module in which a user can combine many matched accelerograms in order to obtain a combined mean matched spectrum that fulfils the user’s requirements regarding maximum and mean misfit.
