ART, Güralp Systems' strong motion analysis and research tool, is a Windows program for processing and analyzing strong motion records from Güralp Systems' CMG 5-series instruments.
Using ART, you can
automatically correct recorded time histories for instrument response, and plot corrected acceleration, velocity and displacement graphs;
filter data with configurable low-pass and high-pass filters, and plot the filtered time histories;
export time histories and spectra in a number of currently-used strong-motion record formats, including ISESD, SMC, CSMIP, K-Net, PEER and SAC;
calculate and plot Fourier amplitude spectra of time histories, and compare them with the pre-event portions of the records;
calculate and plot Arias intensity and energy density;
calculate and plot response spectra on both linear and tripartite graphs;
calculate response and acceleration spectral intensity with user-defined limits;
calculate RMS acceleration and cumulative absolute velocity;
calculate absolute and relative bracketed, significant and uniform strong-motion durations using user-defined limits; and
plot particle motions in 2 or 3 dimensions.
ART works closely with Scream! to make analysing seismic data easy.
Scream!'s visualization and filtering capabilities allow you to view time series and quickly identify events. Records can then be imported into ART with a simple selection operation.
ART 2.0 is supplied in the standard distribution of Scream! versions 4.3 and later. It is also compatible with older versions of Scream!.
ART is included in the standard Scream! distribution for Windows, which is available for free download.
ART uses the Matlab runtime library for its mathematical routines. This is supplied as part of the installer and may be freely distributed.
To download Scream!, send us an e-mail at scream@guralp.com, including information about your institution and the type(s) of equipment you are using.
To install the package, double-click on its icon and follow the instructions in the installer. Choose the Typical installation option to ensure that ART and its supporting libraries are all installed.
