QuakeManager Version 3!

We are excited to announce the release of QuakeManager V3!

QuakeManager Version 3 brings a range of powerful new features and improvements to streamline ground motion selection and modification workflows.

This version introduces new features and major improvements including: 

  1. Expanded Code Design Spectra Support
  2. Improved GM Suite Selection (QuakeSelect Module)
  3. QuakeLibrary Improvements (Additional Database support)
  4. QuakeSignal: New Signal Processing Tools in QuakeSignal
  5. Polar Tool and Chart Enhancements

 

Exapanded Code Design Spectra Support

Added support for many Code Design Spectra including ASCE 7, ASCE 41, NEHRP, IBC, CBC and AASHTO codes, with automatic import from USGS Design Maps and hazard parameter from USGS webservices using the Lat/Long coordinates of the site. Also added support for multi-period spectra in ASCE 7-22 and NEHRP 2020.
 

Figure: Improved Code Design Response Spectrum tool now supports automatic download of spectral values for design codes including multiple editions of ASCE 7, ASCE 41, NEHRP, IBC, CBC and AASHTO.

QuakeSelect: Improved Filtering in GM Suite Selection

Improved GM Selection tool by adding a new selector tool for easily selecting collections, and enhancing record filtering options by adding the following filtering fields:
  1. Mechanism (Strike-Slip, Normal, Reverse, etc.)
  2. Regime (Active Tectonic, Subduction, etc.)
  3. Subduction Event Type (Interface and/or Intraslab).
  4. Sampling frequency (hz)
  5. Cumulative Absolute Velocity (CAV)
  6. Arias Intensity (Io)

QuakeLibrary Improvements

In Version 3, we switched to a faster & more secure database engine. Also, expanded the library by:
  1. Adding full NGA-West2 database with ~20,000 records.
  2. Adding full NGA Subduction database with more than 71,000 records.
  3. Adding AFAD Türkiye Mw7.7 Records & aftershocks with more than 1,200 records.
  4. Added support for DYNA File Format.

Figure: The ground motion library has been enhanced by enhacing the NGA-West2 database and adding support for 2 new databases libraries (NGA-Sub and 2023 Turkey).

QuakeSignal: New Signal Processing Tools

We've added a new set of Signal Processing tools to help users perform their work more easily, including:
  • A newly implemented pulse identification tool to Identify pulse wavelets in records and report the pulse period, pulse velocity, and pulse azimuth, and easily visualize the pulse and its effects on spectra,
  • An improved baseline correction tool now allows the user to specify the order of the polynomial used in baseline correction.

Polar Tool & Chart Enhancements

The polar tool has been substantially improved.
FN/FP and pulse directions/orientations can now be visualized in the polar plot. This adds to the existing ability to show orientation of maximum and minimum responses (RotD100 & RotD00), H1/H2, and other orientations.
 
With these improvements, users can easily check how the peak response correlates with key orientations such as H1, H2, FN, FP, etc. at different periods.
 
In addition, time-histories For Fault normal (FN) and Fault Parallel (FP) as well as pulse (Fpulse) histories & spectra for a Triplet can now be plotted directly (on the fly) in time history charts without the need to pre-rotate the records.
 

Figure: Improved Polar Tool. Users can now show FN/FP and pulse orientations and directly superimpose them on the 2D scatter and response envelope plots.
