Elastic acceleration, velocity and displacement response spectra.

Up to eight records generated from one spectrum.

Large range of envelope shapes available.

Real accelerogram adjustment by correction in frequency domain Random process adjustment by correction in frequency domain Artificial Accelerogram Generation & Adjustment: Random set of phase angles with amplitudes calculated by power density function Synthetic accelerogram generation and correction in frequency domain Synthetic Accelerogram Generation & Adjustment:

Four calculation methods employed for the generation of accelerograms:.

Elastic and inelastic acceleration, velocity and displacement response spectra.

Units for both the metric and the imperial system are supported.

However, in those cases where access to real accelerograms is, for whatever reason, challenging or inappropriate, then a tool such as SeismoArtif will be of pertinence and usefulness. SeismoMatch), together with records selection tools, tends to be recommended for the derivation of suites of records for use in nonlinear dynamic analysis of structures. It is noted that the use of real accelerograms and spectrum matching techniques (i.e. Generating artificial earthquake accelerograms matched to a specific target response spectrum using different calculation methods and varied assumptions.

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. 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. It features a user-friendly visual interface and is capable of deriving a number of strong-motion parameters often required by engineer seismologists and earthquake engineers.Īdjusting earthquake records, through wavelet addition, to match a specific target response spectrum. SeismoSignal opens an accelerogram from text files in different formats.įrom text files in different formats, to create their own library of ground motion records and save them all in a single file making it easy to handle and share large numbers of records. To process strong-motion data, featuring a user-friendly visual interface and being capable of deriving a number of strong-motion parameters often required by engineer seismologists and earthquake engineers. Motion parameters, the adjustment of earthquake records to match a specific target response spectrum, or the generation of artificial earthquake accelerograms. SeismoSignal, SeismoSpect, SeismoMatch amd SeismoArtifĬonstitute a suite of programs that are used to carry out basic earthquake records, such as the processing of strong-motion data, the derivation of elastic & inelastic response spectra and Power & Fourier spectra, the calculation of a number of commonly used ground
