The latest shaker in NZ has reminded me ...

I've often heard that the 'seismic code requires ..." but I've never seen a copy of any 'seismic code.'

Just what, exactly, is the 'seismic code,' and where do I find a copy?

Reno,

For me, the most referenced "Code" regarding any Seismic Qualifications would be per the CBC; Title 24, Part 2-Volumes 1 and 2.
(BTW, "CBC" = California Building Code).

The Linked Site below has the CCR Title 24, Parts 1 through 12 available for On-Line viewing, or PDF Download...
... and at no charge!!! (read: "FREE!!!")

CBC T24, Part 2, Vol. 1 Link-----}

Title 24, Part 2, Vol. 1, 2010 California Building Code

Other AHJs / State's Codes, and more T24 Parts On Same Site -----}

US Public Safety Codes

Additionally, Local California Departments of Building and Safety ("DBS") have Bulletins, Requirements, Handouts, etc. per Seismic Qualification.

Lastly, Manufacturers, such as B-Line, have some good Information available for Download.

Several Years back, I had to Compile an array of Seismic Designs and Calcs on a few Projects. These were for Electrical Installs, as well as Generator Pads, and similar "Smaller" Structural Elements.
I downloaded as much as could be found!

It's my experience that each juristdiction has their own method of writing their own "code" just like any other code, ordinance, regs, etc. For example, The IBC has a sceimic requirements and when a local JHA adopt's it, They can ammend to meet their requirements. Its just like snow loading or extreme hot and cold areas. I would imagine in some areas, they produce a centralize document. It varies
