3 days ago How do they differ? The design values provided by the U.S. Seismic Design Maps tool are different than the USGS hazard values because the design values are the lesser of probabilistic and deterministic ground motion values. Also, for the 2009 NEHRP Recommended Seismic Provisions, the 2010 ASCE/… How are design values calculated? The USGS calculated the design values using: 1. hazard values computed by the USGS on a national scale and 2. site-specific procedures for seismic design stipulated in Chapter 21 of the NEHRP Recommended Seismic Provisions and the ASCE/SEI 7 Standard. From both (1) and (…
