Earthquake Software for Response Spectrum Matching

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 [1992] and Hancock et al. [2006] or the algorithm proposed by Al Atik and Abrahamson [2010]. 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.

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 saved in different text file formats (Single-value per line, Time & Acceleration values per line, Multiple-values per line, SMC format, PEER NGA format and Shake (.eq) format) or of reading simultaneously multiple records of the same format.

Creation of the target response 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.

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