Module 1 – estimating ground motion parameters

- Sally Hargraves

For those of you who missed its launch back in March, this is just a reminder that Module 1 of the `Earthquake Geotechnical Engineering Practice’ series is out there for use.  We’d also welcome any feedback to as this will help us determine if any updates or Q&A sheets are required.

Not only does this Module provide some background and an introduction to the series of Modules that are gradually being developed and rolled out by NZGS and MBIE, but it also provides guidance on estimating ground motion parameters.  In essence, Module 1 recommends that geotechnical practitioners should now be using the Bridge Manual for selection of ground motion parameters, instead of the previous well used methods based on NZS 1170.05.  This is a big change for many of us, so it’d be good to get your feedback on how it affects the analysis results in your part of the country.
