Seismic Design Applications

Design Values for Buildings

The Java Application includes hazard curves, uniform hazard response spectra, and design parameters for sites in the 50 states of the United States, Puerto Rico, and the U.S. Virgin Islands. Design parameters are also available for Guam and American Samoa. Parameters are searchable by zip code or latitude and longitude, can be graphed, saved, and printed for later use.

Note: The Ground Motion Parameter Calculator is a Java(TM) Application .
This application also requires an active internet connection to retrieve data from our servers.

For information on anticipated updates to the seismic design values for buildings, please click the following link to a recap of the Building Seismic Safety Council (BSSC) Seismic Design Procedures Reassessment Group (SDPRG – a.k.a., Project ‘07) Workshop.

Please read our Frequently Asked Questions for answers to common problems.
