Java Ground Motion Parameter Calculator

Purpose: Retrieve seismic design parameter values from:
  • seismic building code reference documents at sites in the U.S. and its Territories
  • 2002/96 USGS National Seismic Hazard Maps
Note: The Calculator is a Java Application (™), and it requires an active internet connection to retrieve data from USGS servers.
Input:

Latitude and longitude, or ZIP code
Site Class (optional for some building code reference documents)
Building code reference document:

  • 2009/06/04/03/00 International Building Code
  • 2006/04/03/00 International Residential Code
  • 2005/02/98 ASCE/SEI 7 Standard
  • 2003/00/97 NEHRP Recommended Provisions
  • 2006/03 NFPA 5000 Building Construction and Safety Code
Output:

Design values and spectra from the building code reference document
Seismic Design Category (for some building code reference documents)
USGS Probabilistic Hazard Curves and Uniform Hazard Response Curves at sites within:

  • Conterminous 48 States (from 2002/96 hazard models)
  • Alaska (1998 model)
  • Hawaii (1998 model)
  • Puerto Rico and the U.S. Virgin Islands (2003 model)
