SEAOC Seismic Design Map Software

Click the link above to see the SEAOC and OSHPD developed web interface implementing the USGS web services to retrieve the seismic design data and present it in a report format. This website does not perform any calculations to the table values. To allow the seismic design data to remain free to all, this website is open-source so feel free to copy the source code on github. Please contact us for feedback.

The website currently provides ASCE 7-16, ASCE 7-10, IBC 2015, IBC 2012, NEHRP-2015, NEHRP 2009, ASCE 41-13, and ASCE 41-17 seismic design map data.
