A NEW PROBABILISTIC COMMON-ORIGIN APPROACH TO ASSES LEVEL-GROUND LIQUEFACTION SUSCEPTIBILITY AND TRIGGERING IN ALL CPT-COMPATIBLE SOILS USING ΔQ AND ITS APPLICATION IN ENGINEERING DESIGN

Friday, June 11th, 2021
12:00pm-1:30pm PDT
Zoom

Abstract: Since the introduction of the Seed & Idriss simplified procedure in 1971, liquefaction triggering analysis for sands has continuously been expanded and refined. Questions of soil compositional susceptibility to liquefaction triggering were addressed using the “Chinese Criteria” for more than 20 years until observations by Bray and Sancio (2006) from the 1999 Kocaeli earthquake in Turkey revealed that some fine-grained clayey soils can also trigger in liquefaction. Therefore, considerable uncertainty today exists around the topics of liquefaction susceptibility and triggering of fine-grained and transitional soils. Using (1) a new method for quantifying soil type/behavior called DQ (Saye, Olson, et al. 2017); (2) a novel approach for considering the liquefaction triggering boundary that removes the need for fines content estimation and correction; and (3) an expanded database of 401 liquefaction/non-liquefaction case histories from a variety of soils ranging from clay to course sands, we (Saye, Olson, and Franke 2021) introduce new probabilistic and deterministic models of liquefaction susceptibility and triggering for ALL CPT-compatible soils. These newly-published models demonstrate excellent fit with many of the “tricky” case histories from recent events including Christchurch. Additionally, we (Franke and Olson 2021) identify and present two common design practices in the use of probabilistic liquefaction triggering models that are potentially introducing significant error in many projects. Practical solutions to these erroneous practices are proposed and summarized.

Jay Love
Senior Principal, Degenkolb Engineers
Seismic Design with Viscous Dampers: Retrofit Design Strategies

Abstract: One of the largest hospital facilities constructed in recent years in California, the new Sutter Health California Pacific Medical Center Van Ness Campus Hospital opened to patients on March 2, 2019.The $2.1B project produced a 13-story, 989,230 square foot hospital, including patient beds, diagnostic and treatment centers, and subterranean parking. Van Ness Campus Hospital consolidated the acute care services of two older Sutter Health California Pacific Medical Center (CPMC) campuses to create their flagship San Francisco hospital.

The structural system features a steel moment resisting frame with supplemental viscous wall dampers to reduce earthquake forces. Originally developed and implemented in Japan over the past three decades, this project marked the first application of viscous wall dampers in the United States. Through testing and nonlinear response history analysis, viscous wall dampers are expected to absorb nearly 90 percent of the earthquake energy at the Design Earthquake level.

Bio: Jay Love has more than 40 years of experience, including master planning, structural design, seismic evaluation, and retrofit design. He has considerable expertise in designing specialized buildings, particularly large and complex healthcare facilities. Jay’s notable projects include the new design of the new Sutter Health California Pacific Medical Center (CPMC) Hospital at Van Ness and Geary and the Kaiser Permanente, Los Angeles Replacement Hospital.

EERI San Diego Chapter Webinar Series


APPLYING LESSONS LEARNED FROM COVID-19 TO EARTHQUAKE PREPAREDNESS

Global pandemics and large earthquakes are both events that have a low frequency of occurrence, but a high risk for loss of life and economic losses. As a result, our current experiences with COVID-19 can be useful for discussions about preparing for these “low frequency/high risk” events. Although currently our scientific knowledge and technology are better than they have ever been, in the past six months, COVID-19 has posed challenges for the world despite attempts to prepare for events such as this. This webinar series looks at how scenarios are used as a planning tool, what challenges can be encountered in preparing for events such as these, and what next steps can be taken for earthquake preparedness in our community.


Webinar 1
:
Friday, October 16th, 2020, 12:00pm PDT (day before anniversary of Loma Prieta Earthquake)
Using Scenarios for Preparedness: Comparing Pandemics and Earthquakes

View Recording of Webinar

Abstract:
Scenarios are useful planning tools to help us prepare for future events, particularly events that have a low frequency of occurrence but a high risk of losses associated with them, such as large earthquakes and global pandemics. Several public health scenarios were developed in recent years to better understand and prepare for a global pandemic, prior to the COVID-19 pandemic. This webinar discusses the outcomes and conclusions of these scenarios, a comparison to our current experiences with COVID-19, and a comparison to existing earthquake scenarios and what we can learn from them in an effort to improve earthquake preparedness.

Webinar 2: Friday, October 30th, 2020, 12:00pm PDT
Common Challenges Preparing for Low Frequency/High Risk Events (Earthquakes and Pandemics)
View Recording of Webinar
Abstract: Preparing and planning for events that have a low frequency of occurrence but high risk of loss associated with them can have a number of obstacles that must be overcome in order to achieve success. These obstacles include changing public perception of risk, communicating information to a non-scientific population, and obtaining sustained political and financial support, amongst many others. These challenges are discussed in the context of our current experiences, and how those same challenges are encountered in planning for earthquakes and developing more seismically resilient communities. This webinar will also discuss some of the ways in which these challenges can be overcome by learning from the failures and successes of our experiences with COVID-19.

Webinar 3: Friday, November 13, 2020, 12:00pm PST
Next Steps for Earthquake Preparedness in Our San Diego Community
View Recording of Webinar
Abstract:
Developing communities that are more earthquake resilient and better prepared for large disasters takes time, resources, and lots of planning. This webinar will focus on how to prepare in our community by looking at outreach, developing a group of stakeholders, and identifying short-term and long-term goals for San Diego. This webinar is intended to be more interactive, with discussion amongst stakeholders. The basis for this discussion will be the San Diego Earthquake Scenario released in March 2020, before the pandemic hit the San Diego region.

PURPOSE

This short course will demonstrate software tools from the U.S. Geological Survey (USGS) for site-specific ground motion hazard analysis, and will provide an opportunity for feedback from earthquake engineering users. The most recent edition of the ASCE 7 Standard (Minimum Design Loads and Associated Criteria for Buildings and Other Structures) requires site-specific ground motion analysis formany more structures than did the prior edition. For example, site-specific hazard analysis shall be performed for structures on Site Class D and E sites with S1 greater than or equal to 0.2g, with some exceptions (see Section 11.4.8 of ASCE 7-16). The new site-specific requirements are expected to be part of the 2019 California Building Code.
