Seismic Design Updates for CBC 2019 and Application of Site-Specific Seismic Hazard Analysis

What you will learn:

• Changes to the seismic provisions in CBC 2019
• Overview of the non-ergodic seismic hazard analysis for optimization ground motion studies
• Project case studies

The seismic provisions of the CBC 2019 are significantly different from the previous version and require Site-Specific Seismic Hazard Analysis (SHA) for most sites located on Site Class D and E soil conditions. The site-specific SHA under the new code also requires utilization of the Third Uniform California Earthquake Rupture Forecast (UCERF3), which is more complex than the previous version (UCERF2).

Site-specific, non-ergodic SHA is an increasingly important part of ground-motion hazard characterization for critical projects. While the efforts associated with non-ergodic SHA are considerably higher than traditional, ergodic SHA methods, the resulting ground motion estimates are more accurate and less uncertain, and can result in a more refined and more economical structural design.
