News of our Alumni Please send us your news (professional or personal) for inclusion to this column to Claire Roggero (MSc, 2002) at [email protected]. We want to hear about it! • Rodolfo Sancio (MSc 1999, PhD 2003) of the
Golder Houston office won the 2007 Victor Milligan Award. The Victor Milligan Award is presented annually to a Golder employee who is the lead author of a paper on ground engineering that has been published in either a refereed journal or conference proceedings in the preceding year. Rodolfo won this prestigious honor for his paper “Assessment of the Liquefaction Susceptibility of Fine-grained Soils,” which author Professor Jonathan D.

25th Annual UC Berkeley Geoengineering Distinguished Lecture: It was a great event
The 25th Annual UC Berkeley Geoengineering Distinguished Lecture series took place on May 4th 2007 at the Sibley Auditorium. Professor Nick Sitar from UC Berkeley, gave a talk on “Observational Method in Geotechnical Earthquake Engineering: Can it lead to better design and performance” followed by a talk by Rudolph Bonaparte (MSc 1978, PhD 1981), President and CEO of Geosyntec Consultants titled “Building a Rewarding Career as a Consulting Geoengineer- Perspectives 25 Years After Berkeley”. Then, Professor Whitman presented the 7th Harry Bolton Seed Memorial Lecture titled “Early evolution of earthquake geotechnics – A view from the northeast”. Between talks, posters prepared by graduate students on their research at UC Berkeley were available at the main lobby, and visitors had the opportunity to interact with the researchers. These excellent talks were followed by a no-host social and the banquet at the Mining Building Lobby. The event, which was organized in collaboration with the ASCE San Francisco Geotechnical Section, was an unprecedented success. More than 240 geoengineers attended the lectures and approximately 120 friends attended the banquet. Many alumni were also there, and some of them came from abroad to be present at the event. This was an excellent event overall and a great opportunity to meet many old friends as well as hear about the excellent work that is being done at UC Berkeley. We are looking forward to next year’s event and we hope that you will be there too. Those of you who were not able to make it, Click here for photos from the event . The BGAA will try to make available videos of the talks through our website. Stay tuned.

The Motley View
On Seeking Dirty Work and the Value of Shoveling S--T*
by Dr. Edmund Medley, PE, CEG, F. ASCE (MS 1991, PhD, 1994)
(*A person with a dirty mind would read this as SILT)
I started work in 1959, delivering groceries by bike in West London. By the time I left my teens, I had worked part-time as a sales clerk in grocery, food and book shops, and also had stints as a bookkeeper, a laundry man, a TV Special Effects technician. I later washed dishes on a cargo ship to travel to Canada and by age 25 had spent a few years as a prospector. None of these jobs would likely be considered “professional” by the standard of today’s graduate geoengineer. All of them required me to perform much dirty work; hard, often physically demanding work that sometimes felt demeaning, was often boring, and which too often left me tired, hot (or very cold), wet, and bruised.
Patriotically painting the outhouse
McIntyre Porcupine INEL camp, 2000 feet above glacier of upper Bronsen Creek, Stikine range, BC; 1973
For example: in 1973 I built an outhouse perched above a glacier in the magnificent Stikine Range of British Columbia, a few miles from the Alaska border (requiring a bold Maple Leaf be painted on the roof to deter the occasional flying American intruder). Since the ground was permanently frozen, a cess pit was impossible so I incorporated an empty 45 gallon fuel drum into the edifice. It was a splendid toilet. As I purposefully did not build a door, patrons had a glorious vista of Mt. Kallahan and its glaciers, a view sometimes obscured by mid-summer snow storms. Read more…

Research Students Selection and Modification of Ground Motion Time Histories
A d v i s o r : Norman Abrahamson

Jennie Watson-Lamprey ( e - m a i l : J e n n i e . W a t s o n L a m p r e y @ g m a i l . c o m )
To obtain design time series, it is common practice to select empirical recordings of ground motion and modify them by scaling or by making them spectrum compatible. The computed nonlinear response of a system can vary greatly depending on the records selected even after making the time series spectrum compatible. A method of time series selection based on properties of the structure and ground motion, not simply magnitude and distance, is presented. The procedure is for use in nonlinear analyses that are intended to result in a median global nonlinear response given a design event.
In developing the time series selection procedure the structure specific properties are considered using a proxy of the non-linear system. Using a suite of recorded and scaled ground motions as inputs, a regression analysis is performed to develop a model for the proxy response based on the properties of the record and the proxy. Candidate scaled time series are evaluated to find those that have key record properties near their expected value and yield a response of the proxy that is near the expected response for an event. Those scaled time series with responses near the expected value are selected as the optimum time series for defining average response even if the scale factors are larger than commonly accepted.
Results for applications to structural response and slope stability are presented. The resulting time series selection methods allow for wider magnitude and distance bins for candidate time series, and reduce variability in the response of the system. Read more…

Development of a Probabilistic Simplified Design Procedure for Assessing the Effects of Liquefaction and Lateral Spreading on Bridges A d v i s o r : J o n a t h a n D . B r a y R e s e a r c h S t u d e n t :
Christian A. Ledezma ( e - m a i l : c l e d e z m a @ b e r k e l e y . e d u ) The primary objective of my research is to develop a simplified design procedure for evaluating the effects of liquefaction and lateral spreading on bridges. This simplified design procedure must be developed to work within the PEER (Pacific Earthquake Engineering Research Center) probabilistic performance-based engineering framework in that sources of uncertainty within each step should be incorporated properly. This project will translate pertinent PEER research findings into forms that can be adopted in practice as a probabilistic-based alternative to existing deterministic approaches. The project will attempt to demonstrate how the PEER methodology can be effectively used with simpler design-level analysis methods to make informed decisions.
