Englekirk Center Shake Table Visit and Tour

In one of our previous meetings, EERI had the opportunity to invite our guests to the Englekirk Structural Engineering Center at the University of California, San Diego to view and tour the facility.  Here are just a few photos of the guests.  Thank you again for the support!

Wednesday, September 25, 2013 Dinner Registration

Dear EERI San Diego members and friends,

Hope you had a great and safe summer!

With the Fukushima disaster in Japan and the recent decision to shut down the San Onofre Nuclear Power Plant, there is strong interest in the community to better understand the seismic issues and risks of nuclear power plants. Motivated by these events and by our mission of raising awareness of earthquake risks, the EERI San Diego Chapter, working jointly with the ASCE Geo-Institute San Diego and the San Diego Association of Geologists, invite you to participate in a dinner meeting on Wednesday, September 25, 2013, 6pm at the Tom Ham’s Lighthouse Restaurant.

 We are delighted to have Dr. Annie Kammerer, an earthquake engineer in the Office of Research of the US Nuclear Regulatory Commission, present on this topic. The abstract of her talk and her biographical information are provided below.

 

SEISMIC DESIGN AND RISK EVALUATION OF NUCLEAR PLANTS

Since the beginning of the nuclear power industry, the framework and methods used in the seismic design and risk evaluation of the fleet of nuclear power plants in the US has gone through significant change and advancement. Currently the US regulatory framework uses a risk-informed, performance-based framework that has matured over the last 5 decades and is composed of three steps: probabilistic seismic hazard analysis, seismic design, seismic probabilistic risk assessment.

This presentation will cover a wide variety of topics including:

  • Basic nuclear plant design concepts (how they work and what can go wrong)
  • Why the engineering of nuclear plants is unique and challenging
  • The history of seismic regulations, design approaches, and reevaluation efforts
  • The performance-based and risk-informed methods used in the industry today
  • The impact of the Fukushima Daiichi accident, including current and future NRC efforts

Biography:

Dr. Annie Kammerer is a senior seismologist and earthquake engineer in the Office of Research of the US Nuclear Regulatory Commission, where she is the coordinator and manager of the seismic and tsunami research program.  Her research is principally in the areas of seismic and tsunami hazard and risk assessments, seismic isolation, and technology-neutral approaches to seismic design. Currently she is also the NRC’s technical lead for a special program conducting Seismic Walkdowns of all 104 operating US nuclear plants in response to the Fukushima Daiichi accident.  She is active internationally and chairs an IAEA Working Group on Seismic Re-evaluation of Operating Reactors, as well as special committee developing new guidance on seismic isolation. Prior to joining the NRC in 2006, she was a consultant in the Risk and Advanced Technology groups in the international design firm, Arup.  As seismic hazard lead for the Americas, her consulting work encompassed a wide variety of technical areas including geotechnical earthquake engineering, structural dynamics, seismology and risk assessment.  Her work focused principally in the energy, industrial and transportation sectors and included dozens of projects around the world.  She holds three degrees from UC Berkeley, including a Ph.D. in geotechnical engineering with minors in strong motion seismology and structural engineering.

Seismic Demands for High-Rise Buildings: Interaction between Geotechnical and Structural Engineers

Wednesday, January 18, 2012

Guest Speakers:

Prof. Jack Moehle (Univerity of California Berkeley)

Prof. Jonathan Stewart (University of California Los Angeles)

Performance-based seismic design of tall buildings has evolved in recent years to permit buildings designed outside the prescriptive provisions of the building code. A performance-designed project typically requires definition of performance objectives, development of the structural system, definition of seismic hazard, and verification of seismic performance using nonlinear dynamic analysis. One of the challenges to be overcome in design is the communication of modeling and analysis requirements between structural and geotechnical engineers. The seminar will emphasize the required handoffs.

Dr. Moehle will introduce the recently published PEER Tall Buildings Initiative for Performance-Based Seismic Design of Tall Buildings. The presentation will cover team qualifications, performance objectives, modeling and analysis requirements, performance evaluation, and the review process. The presentation also will review typical handoffs between structural and geotechnical engineers, including typical assumptions for soil-foundation-structure modeling and selection and scaling of earthquake ground motions. Emphasis will be on requirements from the perspective of the structural engineer.

Dr. Stewart will review outcomes of a recent ATC/NIST project on modeling seismic Soil-Structure Interaction (SSI) effects for building structures, with an emphasis on applications to tall buildings. The conditions under which SSI effects are most pronounced will be identified. The basis for the SSI procedures in the PEER Tall Buildings project will be reviewed. Typical problems encountered in the communications between structural and geotechnical engineers for SSI problems will be described along with proposed solutions proposed within the ATC/NIST project.
