Hypothetical Earthquake Ground Shaking Estimation for Performance-Based Design
Introduction
Earthquake engineering design of buildings increasingly is using nonlinear dynamic analysis to demonstrate building performance. One requirement of the nonlinear dynamic procedure is the selection and manipulation of ground motions appropriate to design hazard level.
Seismic hazard due to ground shaking should be determined considering the location of the building with respect to causative faults, the regional site-specific geologic characteristics, and the selected earthquake hazard level. In general, the seismic hazard should include earthquake-induced geologic site hazards in addition to ground shaking.
The discussion here is limited to ground shaking hazard.
