U.S. Geological Survey, 2003, Earthquake Hazards Program: U.S. Seismic Design Maps: U.S. Geological Survey,


The USGS collaborates with organizations (such as the Building Seismic Safety Council) that develop model building and bridge design codes to make seismic design parameter values available to engineers. The design code developers first decide how USGS earthquake hazard information should be applied in design practice. Then the USGS calculates gridded values of seismic design parameters based on USGS hazard values in accordance with design code procedures. The U.S. Seismic Design Maps application provides seismic design parameter values from the following design code editions: 2013 ASCE/SEI 41, 2012/09/06 International Building Code, 2010/05 ASCE/SEI 7 Standard, 2009/03 NEHRP Recommended Seismic Provisions, 2009 AASHTO Guide Specifications [...]
