ART
1 Introduction
ART 3.0, Güralp Systems' Strong-Motion Analysis and Research
Tool is a windows program which allows users of seismometers
(accelerometers or velocimeters) produced by Güralp Systems
Ltd, to process and analyze their recorded data for engineering
seismology and earthquake engineering purposes. The timehistories
can be exported in a number of different strongmotion
record formats that are currently in use today.
ART3.0 is a major update of the second version of ART
(ART2.0), which was released in 2006. A number of
improvements were made following requests received from
users, which are listed in section 5.1, page 60.
ART 3.0 is supplied in the standard distribution of Scream!
versions 4.5 and later. It is also compatible with older versions
of Scream!.
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. Strong-motion
records can then be directly imported into ART from Scream!
by selecting the appropriate portion of the record in Scream! -
this will automatically start ART. Previously recorded data in
Güralp Compressed Format (GCF) can be read in from prerecorded
files and analyzed. In addition, data can be imported
into ART via a modem.
Currently the following functions, which are important for
engineering seismologists and earthquake engineers, are
supported (in addition most of these functions allow selection
of multiple time-histories so a comparison between records is
possible).
• plotting uncorrected acceleration, velocity and
displacement against relative or absolute time;
• automatic correcting of recorded time-history for
instrument response to obtain ground acceleration;
• filtering of acceleration time-history using user-defined
filters;
• plotting corrected acceleration, velocity and
displacement against relative or absolute time;
