ASCE 7 chapter 13 regarding seismic codes for suspended light fixtures

[scubamaster]

Can anyone tell me the rules for a suspended lighting fixture in the state of California? I'm designing the lighting system and I know the fixture needs to swing a certain angle and a backup safety cable might be needed. I need to know what the ASCE 7 says exactly. This is a steel stem mounted system. The California Seismic Safety Commission told me it was in ASCE 7-05 chapter 13. I do not have this book and would rather not have to get it. Any help would be greatly appreciated.

You'll need the book. It discusses non-structural components for MEP and architectural items. This falls under the MEP. You should have a flexible component, but don't fail to read the tables that discuss the respective coefficients. If you are in a low-seismic region, you still have to consider it. It is intended for structures that are intended to be used for habitats during emergency situations (hurricane/earthquake/etc.).

If I were you, I'd simply buy the book. You don't want a plans examiner making you look bad to a client. Keeping your reputation on the west coast is very important if you want future work. A plans examiner on his/her high horse can make your life miserable if you don't know what you're doing.
