[Sprinklerforum] Re: Seismic data outside the US

[Ken Wagoner]

Ben,

I believe if you carefully review the TIA to -13, #22-8, it now uses the value of Sds to figure up the eventual Cp value.  You simply multiply the Sds by 0.754 to get the Cp.  13 no longer refers to the Ss value.

As I am a current member of the hanging and bracing committee, please see the disclaimer below.

sincerely.

Does anyone know where I can find seismic data, specifically for Guatemala?

I found FM Global 2-1 and its maps give you the 50 year zone, which gives Sd1 and Sds, but I need Ss for doing the seismic braces.

Don't know how to get from Sd1 and Sds to Ss though, if that's even possible.

Any pointers in the right direction would be appreciated.

Thanks,

Benjamin Young
