SeismoMatch is an application capable of adjusting earthquake accelerograms to match a specific target response spectrum, using the wavelets algorithm proposed by Abrahamson [1992] and Hancock et al. [2006] or the algorithm proposed by Al Atik and Abrahamson [2010]. It gives users 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.
 
The program is capable of reading single accelerograms defined in both single- or multiple-values per line formats (the two most popular formats used by strong-motion databases) or of reading a number of accelerograms at the same time (if they are defined in the single-value per line format). This collection of ground motion records can then be adjusted in a way that their spectral acceleration matches within a certain tolerance a pre-defined response spectrum. Currently, the target spectrum can be created by following rules from a selection of more than 25 National Building Codes including Eurocode 8, ASCE 41-13 and various Regulations worldwide, by computing the spectrum of a specific accelerogram or by simply loading a user-defined spectrum. The following strong-motion parameters are then computed for the matched accelerograms:
 
  • Elastic response spectra and pseudo-spectra
  • Oscilators time histories for a large collection of fundamental periods
  • Overdamped and constant-ductility inelastic response 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)
  • Acceleration (ASI) and velocity (VSI) spectrum intensity
  • Predominant period (Tp)
  • Significant duration
 
In addition, SeismoMatch also feautures a module in which a user can combine many matched accelerograms in order to obtain a combined mean spectrum that fullfils the user's requirements regarding maximum and mean misfit.
 
Finally, and due to its full integration with the Windows environment, SeismoMatch allows for numerical and graphical results to be copied to any Windows application (e.g. MS Excel, MS Word, etc.), noting that the characteristics of the plots can be fully customised from within the program itself.
