Seismic Design Map Tool

SEAOCC and OSHPD have developed this website interface that queries the U.S. Geological Survey (USGS) web servers and retrieves the seismic design variable in a report format.  The website currently provides ASCE 7-16, ASCE 7-10, ASCE 41-13, ASCE 41-17, IBC 2015, IBC 2012, NEHRP-2015, and NEHRP 2009 seismic design map data. We will add more reference documents to the website as USGS adds more to their server. 


This is a free Seismic Design Tool for SEAOC members, non-members, industry partners, and the public.
