Abstract

A review of seismic hazard description in United States design codes and procedures is presented in this paper. This review includes: history of seismic hazard maps; development and use of seismic hazard maps; and use and adoption of seismic building codes in the US. The review includes discussion of two paradigm shifts. The first paradigm shift occurred in the 1970s when seismic hazard was described as contour maps of probabilities of peak ground accelerations being exceeded. The second paradigm shift occurred in the 1990s and led to the development of a new concept for describing the use of seismic hazard maps in US seismic design codes.
