We all know the Puget Sound region can be subject to very large earthquakes. We have heard the predictions for many years. The M9 Project is a 6-year, interdisciplinary research project at the University of Washington, that was developed to investigate the impacts of a Magnitude 9 Cascadia Subduction Zone earthquake on the Pacific Northwest. Researchers have used physics-based computational ground motion simulation to produce regional predictions of ground shaking that include the effects of the deep sedimentary basins that are present in major urban areas.

UW structural engineering researchers characterized the resulting ground motions using parameters that correlate well with structural performance and compared them to the more conventional crustal earthquake records that underpin our understanding of structural response. This has revealed that that M9 simulated ground motions have more damaging characteristics. Detailed structural analysis of reinforced concrete shear wall archetype buildings, developed in collaboration with SEAW, were then performed to estimate building response to simulated ground motions. The results indicate that the probability of collapse of reinforced concrete shear wall buildings for the M9 motions is larger than the maximum currently targeted by building codes. 

 Benefits and knowledge attendees can expect to take away from the presentation:

-A fundamental understanding of basin amplification of strong motion.
-The particular impact that basin amplification has on the Cascadia Subduction Zone ground motions.
-The corresponding consequences for building structures in Seattle


Jeffrey Berman, Ph.D., University of Washington
Dr. Berman is the Thomas and Marilyn Neilson Professor of Structural Engineering in the department of civil and environmental engineering at the University of Washington. His research strives to blend experimental and analytical investigations to help develop the tools and understanding necessary for practicing engineers to design structures to resist the forces of earthquakes, blasts, and other hazards. He is a co-Principal Investigator on the M9 Project, the Operations Director for the NSF supported NHERI Rapid Facility, has served as the Director for UW the Structural Research Laboratory and led the acquisition of the UW’s large-scale X-Ray CT scanner. His research on steel plate shear walls and braced frames are cited in the AISC Seismic Provisions. He is also an Associate Editor for the Journal of Structural Engineering and is a past recipient of the UW Distinguished Teaching Award.

Marc Eberhard, Ph.D., University of Washington
Dr. Eberhard is a professor in the Department of Civil and Environmental Engineering at the University of Washington, who teaches and performs research in earthquake engineering and the performance of reinforced concrete structures. He was awarded the PCI Charles Z. Zollman Award in 2013, the ASCE T.Y. Lin Award in 2014, and was named the 2018 Academic Engineer of the Year by the Puget Sound Engineering Council.
