Seismic Response Accelerations and Site Coefficients for 2012 and 2015 IBC

Seismic Response Accelerations and Site Coefficients for 2012 and 2015 IBC

Seismic Response Accelerations and Site Coefficients for 2012 and 2015 IBC

(OP)
I have been trying to spot any significant changes within section 1613 of the 2015 IBC concerning response accelerations and site coefficients. As far as I can tell, there seems to be little change in this section of the 2015 code. However, the USGS seismic tool only references up to the 2012 IBC on there website, and this is how I usually determine the Ss, S1, SDS, SD1, SMS, SM1, Fa, & Fv. Looking for some guidance or comments from anyone here, thanks in advance!

hawkaz - thank you for responding. I re-ran the coordinates for our site and they are still the same. Thank you again for pointing out that update on the usgs site.
