What Can EZ-FRISK™ Do for Engineers?

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.

Using EZ-FRISK™:

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.
