Enabled the visualisation of Ground Motion Parameters for both unfiltered and filtered recordsģ. Increased the maximum allowed number of accelerogram data points from 2^15 (still the maximum for Fourier and Power spectra analysis) to 2^18, i.e. * SeismoMatch download link provides trial version of the software.1. MS Excel, MS Word, etc.), noting that the plots characteristics can be fully customised from within the program itself. In addition, SeismoMatch also features a module in which a user can combine many matched accelerograms in order to obtain a combined mean spectrum that fulfils the user's requirements regarding maximum and mean misfit.įinally, 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.

Sustained maximum acceleration (SMA) and velocity (SMV).

Acceleration (ASI) and velocity (VSI) spectrum intensity.

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

Arias (Ia) and characteristic (Ic) intensities.

Root-mean-square (RMS) of acceleration, velocity and displacement.Overdamped and constant-ductility inelastic response spectra.Elastic response spectra and pseudo-spectra.The following strong-motion parameters are then computed for the matched accelerograms: Creation of the target spectrum by following rules from a selection of more than 25 National Building Codes including Eurocode 8 rules, ASCE 41-13 and various Regulations worldwide, by computing the spectrum of a specific accelerogram or by simply loading a user-defined spectrum.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).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.Simultaneous matching of a number of accelerograms, and then creation of a mean matched spectrum whose maximum misfit respects a pre-defined tolerance.

or the algorithm proposed by Al Atik and Abrahamson. 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.
