SeismoMatch is an application capable of 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 be used in combination with record selection tools to define adequate suites of records for nonlinear dynamic analysis of structures.

Some of its features are:

Simultaneous matching of a number of accelerograms, and then creation of a mean matched spectrum whose maximum misfit respects a pre-defined tolerance.

Possibility of using this software 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.

Capability 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).

Creation of the target spectrum by following Eurocode 8 rules, 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

Overdamped and constant-ductility inelastic response spectra

Root-mean-square (RMS) of acceleration, velocity and displacement

Arias (Ia) and characteristic (Ic) intensities

Cumulative absolute velocity (CAV) and specific energy density (SED)

Acceleration (ASI) and velocity (VSI) spectrum intensity

Housner intensity

Sustained maximum acceleration (SMA) and velocity (SMV)

Effective design acceleration (EDA)

Predominant (Tp)

Significant duration
