EZ-FRISK v8.10 is now available!
This version brings these new features:
Added in version 8.06:
Finalized USGS 2014 NSHM Seismic Source Model
Available since version 8.06, EZ-FRISK implements the USGS 2014 Seismic Source and Ground Motion Models. This version and model improve hazard calculation prediction for subduction sources and the U.S. Pacific Northwest.
Added in version 8.0:
NGA West2 Ground Motion Prediction Equations
EZ-FRISK is a software package used by engineers and seismologists to perform site-specific earthquake hazard analysis. The key capabilities include:
Calculating the probability of earthquake ground shaking at the surface or in the bedrock beneath a site based on the location of surrounding faults.
Adjusting an accelerogram to match a target response spectrum, while preserving realistic time-dependent characteristics of the ground motion.
Calculating the ground motion at the surface given a bedrock ground motion and the layers of soil and rock that overlay the bedrock at the site.
With this set of features you can quickly create design ground motions for engineering purposes that
EZ-FRISK lets you quickly set up, execute, and visualize seismic analyses because it has an integrated, intuitive user interface and has databases of earthquake faults characteristics, ground motion attenuation equations, and dynamic soil properties that are extensive and up-to-date, yet can be customized as needed.
You do not need to rely on generic published maps. You do not need to rely on command-line engineering tools and their tedious and error-prone data entry, file conversion, and manual chart creation. Instead, you can concentrate on applying your expertise and judgment because EZ-FRISK gives you an effective, integrated set of seismic analysis tools that are easy-to-use yet powerful and flexible.
EZ-FRISK capabilities work together as an integrated package, or you can use and license them as stand-alone modules.
EZ-FRISK gives geotechnical and structural engineers the ability to:
With EZ-FRISK it is practical to perform detailed seismic hazard analysis on nearly all construction projects, not just the big ones. The process of creating site-specific design events is simple and quick, making this an ideal task to add to your standard offering to your clients. Structural and soil engineers can use these site-specific design events to identify cases where building and soil-structure costs can be reduced by detailed analysis.
EZ-FRISK comes with an extensive collection of attenuation equations which is frequently updated to include newly published work. The seismic hazard analysis module comes with seismic sources for one region. You can license additional regions at additional cost.
The following regions and seismic sources are available. Click on each more more information.
EZ-FRISK includes an integrated suite of seismic hazard tools implementing industry standard algorithms accessed through powerful and easy-to-use user interfaces.
EZ-FRISK has a project-oriented user interface that allows you to work with a logically related group of seismic hazard, spectral matching, and site response analyses. This facilitates sensitivity studies and refined analyses as a project evolves through its stages. We make it easy to update dependent analyses when underlying assumptions need to be changed. We provide tools and capabilities to organize and annotate your analyses with titles, notes, and comments.
EZ-FRISK displays plots of all output. You can customize the automatically created plots to customized publication quality figures.
Before you register, you should decide what features you need. The Technical Capabilities section can help you choose. Most users will want the 12-month subscription to seismic hazard analysis, spectral matching, and site response analysis. This package gives you a powerful set of site-specific seismic analysis tools. If you have any questions, contact Support.
Registration is a simple process that takes only a few minutes. You choose a user name and password, and provide contact information. Then you select your initial purchase options, and provide payment information. After you accept the license agreement, you are given an opportunity to download the software. At this point, you can install the software on your computer. The software is activated within one business day of your payment clearing — usually within hours of registering when you provide credit card information during registration.
You can renew your subscription by visiting Your Account or contacting Support. In addition, we will contact you near the end of your subscription at the email address you provide during registration (or subsequently update).
EZ-FRISK is typically licensed on a subscription basis for each user, with the subscription period lasting for 3 months or 12 months. A subscription is locked to a particular computer, although we will allow you to move a subscription to another computer under specific circumstances. You must purchase a license for each computer on which EZ-FRISK will be used. Multiple licenses within an organization may qualify for a volume discount.
The seismic hazard module can be licensed on a site basis, with a site defined as one latitude and longitude pair to be studied.
The EZ-FRISK software has a number of modules:
Each module may be licensed separately or you may license a combination of modules. License fees depend upon the duration of the subscription and the modules to be licensed, and for seismic hazard analysis the regions to be licensed.
The seismic hazard analysis module is licensed for analyzing sites in particular regions. The basic license includes a single region, and additional regions can be licensed for additional cost.
EZ-FRISK Windows Vista or any newer version of Windows. The program requires 300 mb of disk space. During typical use, EZ-FRISK requires access to the internet for authentication, authorization, and downloading of regional data. This access is via the standard SSL port 443. This access can be through an standard authenticating proxy server if necessary. Offline authentication and authorization is supported for users who are unable to appropriately configure their organization firewall to allow the EZ-FRISK executable to access the internet.
Please note: Offline authorization is much less convenient for the user than online authorization.
EZ-FRISK is installed locally and uses the internet for the following:
EZ-FRISK is a program that runs on computers using the Microsoft Windows operating system. Upon execution the program establishes a connection to our web server, whereby the site usage can be monitored and prepurchased credits appropriately recognized.
The program tracks usage by monitoring the latitudes and longitudes of your analysis sites. Each new site location is realized by the server and a credit is deducted (at execution time). You can run as many sensitivities and parametric studies as you wish for each site without any credit penalties.
Each time the software is started up you will be prompted for a username and password. These are established during the registration process. Down the road you can manage your account and purchase additional site evaluations with this username and password so please remember what you have entered (we have no access to the password).
We will be notified of any changes you make to your account. We also provide support for any questions or reasonable requests you make.
