Seismic Bracing
Seismic Bracing
You have to refer to IBC to seeing if seismic bracing is required for non-structural components. Usually the structural engineer on the project can help you out with this but if not, here are the basic steps you need to follow...
- determine which version of IBC you need to follow, either IBC 2000, 2003 and 2006. You can easily check this by going to
http://www.iccsafe.org/government/adoption.html
- determine which seismic use group you fall under, either I, II III or IV
- determine the Spectral Response Acceleration Coefficients. You can determine this by taking the zip code and going to
http://eqint.cr.usgs.gov/eq-men/html/zipcode-06.html
- determine the Seismic Design Category (or Occupancy Use Category), which will be A, B, C, D, E or F
Based on this category, you can determine if seismic bracing is required for your project. Of course, I over simplified this a little. Each version of IBC is a little different but from my experience, no matter what version you use, the answer always comes out the same.
