I just finished reading an article with the above title in the latest "Building Design & Construction" Magazine (June 2003 issue, p. 52, also on the web at It gives a summary of the IBC 2000 code changes regarding seismic design requirements under the new code.
One of the biggest changes is the effect that the soil classification has on seismic design requirements. Areas of the country that previously had no seismic requirements may now be affected, under certain soil conditions, simply because of the type of soil!
I'm wondering if the geotechs are now providing the Seismic Design Category for a site in their soils reports.
