Seismic Hazard Analysis
Geotechnical and structural engineers need to be able conduct a Probabilistic Seismic Hazard Analysis (PSHA)
for a site accurately, efficiently, and reliably.
You no longer have to depend on maps and interpolations. You can perform
a site-specific analysis that is more accurate and contains
much more informative results.
You do not need to perform extensive, tedious, and error-prone data entry.
For many parts of the world, Fugro Consultants can license you databases of fault, area, and
background seismic sources consolidated from information obtained
from the USGS/CGS, the Canadian Geological Survey, and from proprietary studies.
A large set
of attenuation equations is included with EZ-FRISK™,
which can be adapted and extended as needed. Since you do not
have to reenter source and attenuation data for a particular analysis,
there are fewer opportunities for data-entry errors.
You can quickly perform an analysis, especially for locations covered
by our standard seismic source databases. We provide a powerful user
interface that makes setting up a new analysis a snap.
You benefit from newly introduced technology. We are constantly updating
the software to include the latest technology, such as newly-published
Spectral Matching of Accelerograms
EZ-FRISK™ includes an easy-to-use graphical user interface
to Norm Abrahamson's spectral matching algorithm, RSP MATCH. This
algorithm operates in the time domain, preserving the time-dependent
characteristics of the original accelerogram. You can quickly create
an adjusted, base-line corrected, acceleration time history that has a
response spectrum matching a target spectrum. You can enter your
own target spectrum, or use one based on a seismic hazard analysis
uniform hazard spectrum.
Site Response Analysis
EZ-FRISK™ provides a user interface to set up the soil
and rock profile at a site and then perform site response analysis using
SHAKE91. You can easily visualize depth profiles, response spectra, and
time histories of stress, strain, spectral acceleration, velocity, and
displacement. Outcropping ground motions can be exported for use
with seismic structural analysis.
