The 2020 PEER Annual Meeting with the theme of “The Future of Performance-Based Natural Hazards Engineering” was held on January 16 & 17, 2020. Please see the summary of first day morning & afternoon. Day 2 started with Plenary 5 “Resilience by Reconnaissance” moderated by Khalid Mosalam and focused on a variety of hazards. StEER team leaders Tracy Kijewski-Correa, David Prevatt, and David Roueche summarized the benefits of coordinated reconnaissance for several recent events. Venkatesh Kodur provided a look at condition assessment of fire damaged structures and Patrick Lynett focused on building resilience against tsunami hazard.
Three concurrent sessions followed this plenary. Concurrent session C1 was on Geo-Hazards moderated by Norman Abrahamson and Tom Shantz, and featured presentations by Norman Abrahamson, Nicholas Sitar, Ahmed Elgamal, and Yousef Bozorgnia. Topics included Non-ergodic Ground-Motion Model for California, DEM Modeling of Influence of Depositional Fabric using XRT data, Shake-table tests to investigate soil-pil-interaction during liquefaction, and NGA Subduction.
Concurrent session C2 was on Bridges & Transportation moderated by Ian Buckle and had presentations by John Stanton, Denis Istrati, Amit Kanvinde, and Farzin Zareian. Presentations included seismic evaluation of California high speed rail systems, Tsunami loads on skewed bridges, Base connections for moment-frame structures, and Physics-based ground motions.
Concurrent session C3 was a focused session on the PEER-CEA wood frame cripple wall project moderated by Janiele Maffei with presentations by Yousef Bozorgnia, Evan Reis, David Welch, and Sharyl Rabinovici. They covered different aspects the project: Overview, Comparison with insurance loss models, Numerical simulations and Communicating Brace & Bolt benefit.
