SEAOC Board NewsBy Bret Lizundia

The SEAOC Convention was held at Squaw Valley on September 27-29. It was well attended with approximately 430 participants, the technical presen-tations were interesting, and the many social events were well organized. Congratulations to SEAOCC for being an excellent host.

The SEAOC State Board meeting was held in conjunction with the conven-tion. Committee objectives and a draft budget for the coming year were re-viewed in detail. I’d like to pass on a summary of some of the key decisions and discussions that occurred.

The State Seminars Committee, chaired by SEAONC’s Constantine Shuhaibar, has held seminars in Sacramento and Southern California on SEAOC’s new 2006 IBC Structural/Seismic Design Manual (SSDM) series. This SSDM series provides a wealth of design examples based on the International

Building Code (IBC) provisions. Both seminars were very well attended. SEAONC’s version of this seminar will be on the evenings of November 1 and 8, 2007. With the upcoming January 1, 2008 deadline for local jurisdictions to adopt the 2007 California Building Code and its underlying IBC provi-sions, this seminar will be valuable and timely.

The SSDM series focuses on new build-ings. The State Board approved a pro-posal for a design manual covering ex-isting building seismic evaluation and rehabilitation examples using the 2006 International Existing Building Code (IEBC) provisions. Design manual ex-amples will include URM bearing wall buildings, tilt-ups, cripple walls, tuck-under apartment buildings, and non-ductile concrete moment frames. The volume is expected to be published in 2009.

The State Public Relations commit-tee recommended that SEAOC adopt a consolidated statewide public rela-tions effort utilizing the services of an outside consultant, likely to be the same consultant that SEAONC has been using quite effectively over the last year. Some specific objectives include planning sessions in each re-gion with media liaisons, developing relationships with key media contacts, pitching topics to the media as seeds for future stories, assisting in develop-ing press releases on various topics, and supporting designated regional spokespeople. The Board approved the proposal as a one-year trial pro-gram.

Committee chairs traditionally ro-tate at the Convention meetings. The 2007-2008 State Seismology and Struc-tural Standards Chair will be Kevin Moore of SEAONC. Outgoing Chair John Diebold will focus over the com-ing year on overseeing the effort of completing the next edition of the Bluebook. It addition to finishing the online version, they also plan a hard copy compilation of the articles by the 2008 state convention.

um. The aquarium water surrounds the visitor on top and around the sides. In effect, the visitor is in an air bubble within the aquarium. Arup performed seis-mic time history analyses on a 3D model of the aquarium structure (glass acrylic shells) together with the contained water to determine the feasibility of the com-plex design. The analysis predicts the stresses in the glass elements explicitly in the time domain.

Striving to achieve a Platinum LEEDTM rating, the building’s sustainable fea-tures include a “green roof,” natural ventilation, extensive use of natural daylight, reduced water run-off, alternative transportation, and integration into the park and community. Performance characteristics indicate that the new building will achieve significant benefits in terms of energy efficiency, reduction of stormwater runoff, minimization of heat island effects and reduced biodiversity impacts.

Aquarium tanks have been designed to be interchangeable and reusable, which avoids waste and facilitates maintenance. “Green” cleaning programs ensure that products harm neither the staff, living organisms, nor the environment. Simi-larly, the landscape has been designed to manage pests without use of pesticides. Even the café will be run in a sustainable fashion, with organic fare and on-site composting. The Academy will continue its tradition of providing discounts to visitors that arrive using public transit. Docents will highlight these sustainable practices and more in behind-the scenes tours of the Academy. Once open, the museum’s operational savings will allow directors to spend more of their endow-ment on innovative exhibits, rather than on operations and maintenance.

Members in the News

T. R. Higgins Lectureship Award to Lopez & Sabelli SEAONC members Walterio Lopez and Rafael Sabelli received AISC’s T.R. Hig-gins Award for their paper on buck-ling-restrained brace frames, “Seismic Design of Buckling-Restrained Braced Frames”. Each year the T.R. Higgins Lecture-ship Award recognizes an outstanding lecturer and author whose technical paper or papers, published during the eligibility period, are considered an outstanding contribution to the engi-neering literature on fabricated struc-tural steel.The Abstract of the paper states that Buckling-Restrained Braced Frames (BRBFs) are a new steel seismic-load-resisting system that has found use in the western United States because of its efficiency and its promise of seis-mic performance far superior to that of conventional braced frames. The sys-tem was not yet addressed in the 2005 edition of the AISC Seismic Provisions for Structural Steel Buildings, but nev-ertheless a set of design provisions has been developed by AISC in conjunction with the Structural Engineers’ Associa-tion of California. The system has sub-seqnently been incorporated into the AISC Seismic Provisions. This report illustrates the seismic design of buck-ling-restrained braced frames; they are defined, and the provisions govern-ing their design and required testing are explained. A summary of selected Buckling-Restrained Brace (BRB) test-ing performed to date is provided. Compliance with design requirements is explained through detailed compo-nent design of two typical BRBF con-figurations and development of testing protocols. A discussion of gusset-plate design and its influence on acceptable frame behavior is provided.

YMF Spotlight: Meaghan HalliganBy Christopher Ong and Heinz Kuo

This month, YMF is happy to spotlight Meaghan Halligan, a young engineer at Rinne and Peterson Structural En-gineers in Palo Alto. Meaghan is the current chair of the Disaster Emer-gency Services (DES) Committee and a member of the Continuing Educa-tion Committee (CEC). She received her Bachelor of Applied Science in Civil Engineering from the University of Waterloo in Ontario, Canada and worked at Read Jones Christoffersen in Vancouver before moving down to the San Francisco Bay Area to join her hus-band, who is in the tech industry. In San Francisco, she worked at Murphy Burr Curry(MBC) before moving down the peninsula.

In between work, volunteering and renovating her townhouse, Meaghan does indoor rock climbing and road biking. She recently biked four-and-a-half passes of the Death Ride, for a total of 129 miles and a climb of 15,000 feet, in the California Sierra. A pass is a low place in a mountain range, by the way.

Let’s find out what Meaghan has to say about her experience as an engineer thus far…

YMF: University of Waterloo in On-tario offered you an interesting educa-tion involving a fair amount of work experience. Would you elaborate on this?

My university has a compulsory work experience component to our degree. We would go to school for a 4 month semester, and than do an internship at a company for four months. Some of the internships I completed were at a manufacturing facility, a public utility and as a facilities construction coordi-nator at an oil refinery. My last three internships were at Read Jones Christ-offersen, a consulting firm with offices throughout Canada. I worked for two terms at the Toronto office and one at the Vancouver office. They do quite a bit of work for Intrawest in Tahoe.

YMF: You’ve worked in San Francisco and on the Peninsula. Please give us a picture of what working life in the

peninsula is like for those of us work-ing in the City.

I think there is a perception amongst some people in the city that we don’t work on exciting projects on the pen-insula / south bay. I would have to disagree with that. Currently I am on a team working on a community cen-ter and large library in San Jose with skewed concrete tilt up shear wall pan-els for the town square and banquet facilities, and a steel special concentric braced framed library building. I also just finished working on a concrete shear wall theatre building.

YMF: What are the one or two most interesting projects you have worked on? What did you learn from them and/or how were they formative in your career path?

At MBC, I was involved in quite a few probable maximum loss assessments and a couple of Building Occupancy Resumption Program (BORP) reports. It was fascinating to look at existing buildings and identify their potential strengths and weaknesses; not just from a structural point-of-view, but also from a nonstructural standpoint. I think this really helps when designing new buildings – to think about what can go right and what could go wrong in a particular construction method.

YMF: Tell us about your involvement on SEAONC’s Disaster and Emer-gency Services Committee. How did you get involved? What are the com-

mittee’s goals and what is the state of progress toward these goals?

I became involved in the DES through my involvement in the city BORP pro-gram. Jeff Falero recruited me at one of the BORP meetings at the Building Department.

For those not familiar with the com-mittee, we are responsible for deploy-ing volunteer safety assessors after disasters through the state Office of Emergency Services department. We run ATC 20 training sessions to train said volunteers, and help to recruit structural specialists for the two area Urban Search and Rescue teams. Our final mandate is to be involved with the San Francisco BORP.

This year we are working on alternate communication methods for deploy-ing the SEAONC volunteers. Currently we use a phone tree system, but we are identifying other methods which may be quicker and more efficient.

This year we are also planning an ATC 20 training session for the end of Octo-ber 2008.

YMF: Congratulations on being se-lected as a recipient of the Giles Schol-arship! Was this be the first time you attended a SEAOC convention? What was your experience like at this year’s SEAOC Convention?

Continued on page 5

- 5 -

This was my first convention, and it was great. The technical sessions were extremely informative and the social events were a lot of fun. It was great talking shop with members from not only our section, but also members from all over California. People are working on some very interesting proj-ects and research.

I would highly recommend that every-one attend the conference. I think there may be a perception that the SEAOC convention is mostly for principals, but I got a lot out of going to it and I am already planning on attending next year’s conventions.

YMF Spotlight is a monthly article, high-lighting some of the talented young per-sonalities that characterize the SEAONC community. If you would like to nominate a young engineer with an interesting per-spective to share, please email Christopher Ong [email protected]

“YMF Spotlight” Continued from page 4 SEAONC YMF Classroom PresentationAre you interested in teaching a young audience about structural engineer-ing? A classroom program to educate middle and high school students about structural engineering is ready and available for use. The program consists of a PowerPoint presentation and a hands-on activity. The entire program is de-signed to take about 45 minutes.

The start of the program is a 15-minute PowerPoint presentation designed to introduce students to structural engineering concepts including types of struc-tures, loads and materials, as well as to explain the role of a structural engineer in a construction project. The presentation concludes by identifying the skills and education requirements necessary for being a structural engineer. Not only does the presentation include exciting and carefully-selected pictures, but it also contains speaker’s notes (in both verbatim and outline format) to guide the speaker through the talking points of each slide. The presentation can also be customized by the speaker for an audience ranging from middle school to high school seniors. There are also a couple of “bonus slides” included in the presen-tation on cutting edge structural engineering concepts for the more mature or technically inclined audience.

The hands on activities, which should take about 30 minutes, are designed to demonstrate one of the concepts addressed in the presentation and to promote teamwork in the classroom. Four different activities have been developed for presenters from which to choose from: building “skyscrapers,” breaking paper-clips, making “edible concrete,” and building bridges. The first activity consists of building a model skyscraper using only toothpicks and gum drops. Students are to make the tallest structure they can in a given amount of time, and the structures will then be judged for height, stability, and aesthetics. The second activity involves students breaking different size paperclips to explore con-cepts of statistics and ductility. The third activity is to make “edible concrete” using cookies and instant pudding to educate students about the components on concrete in a fun way. The fourth activity requires students to build bridges out of paper. The bridges are then “field tested” to determine how much paper they can hold before they collapse. Instructions for each activity include a list of required materials, a description of concepts illustrated by the activity, and suggested discussion questions.

The classroom program was developed by the School Curriculum Develop-ment YMF subcommittee over the past year. The subcommittee comprises Jeff Ching, Lissa Hoffman, Sara Hohenshelt, Kristen Parrish, and Larry Wong.

The next step for the YMF subcommittee is to test out the program on students at different schools. The goal is to do a number of classroom presentations dur-ing Engineers Week in February. YMF plans to collaborate with the Public Af-fairs committee and Engineering Alliance for the Arts in this effort.

The presentation is available for download at the SEAONC website. Please go to http://www.seaonc.org/member/committees/ymf_docs.asp. Any questions and/or suggestions about this program can be directed to [email protected].

Firing Up for Change…A Performance-Based Approach to Fire Engineering

by Bevan Jones – Holmes Fire & Safety/Holmes Culley

Prescriptive Fire Codes mandate a minimum level of safety; however, these apply a ‘cook-book’ type approach to increasingly com-plex situations. Performance based fire engineering design is a widely accepted practice internationally, and, like performance-based structural engineering, fire safety designs can be ‘tailor-made’ to suit a particular building, achieving functionality and flexibility without “recipes.” This presentation covers a performance based approach to the fire protection of structural steel, synergies between structural engineering and fire engineering, and considerations for structural engineers when specifying and inspecting fireproofing materials to steel structures.

Bevan is a fire safety specialist with Holmes Fire & Safety, an affiliate of Holmes Culley in San Francisco. He has over 6 years of inter-national experience with performance based fire engineering design and holds a master’s degree in fire engineering.

Collapse Test of Full-Scale Building in JapanBy Bruce Maison, Kazuhiko Kasai, Gregory Deierlein

A full-scale, 4-story tall, welded steel moment frame building was shaken to collapse on September 27, 2007 using the E-Defense shake table in Miki, Japan. Figures 1 and 2 depict the structural system. The structure reflects current Japanese de-sign criteria and construction practices. These differ in several important ways from those used in the US: all frames were moment resisting; columns consisted of square HSS elements (that do not satisfy AISC compact section criteria); columns were interupted by through-plate diaphragms used to connect the girder flanges to the columns, and while a strong col-umn-weak girder design philosophy was used, bi-directional loading and composite action were not considered. Japanese seismic mass computations, lateral loading provisions, and drift criteria also differ from those used in the US. The collapse test was part of NEES/E-Defense Collaborative Earthquake Engineering Reseach Program, and funded by the Japanese Ministry of Education, Culture, Sports, Science and Technology. It was supervised for E-Defense by Prof. Keiichiro Suita of Kyoto Univ., Prof. Satoshi Yamada of Tokyo Institute of Technology, and Yuichi Matsuoka of E-Defense.

The building was subjected to three components of the JR Takatori Station motion recorded in Kobe, Japan at the during the 1995 Hyogo-Ken Nambu earthquake (Figure 3). The building was initially subjected to motions scaled to correspond to the DBE and MCE levels. Observed behavior during the MCE excitaiton included moderate yielding in the first story beams, and yielding and minor local buckling of the columns in the first story.

Collapse occurred when the ground motion intensity was increased to the level actually recorded in Kobe. This motion resulted in spectral accelerations more than 2.5 larger than stipulated in Japanese design codes. The collapse mode was a side-sway mechanism in the first story (Figure 4). Plastic hinging and severe local buckling were observed at the bottom and top of the first story columns, with little evidence of significant girder yielding (Figure 5). No fractures of welds or base metal were observed. Preliminary findings indicate that several factors contributed to the weak story collapse mecha-nism, including: actual strengths of girders being larger than those of the columns due to actual steel properties and com-posite action of the girder and slab; strength deterioration of the non-compact HSS columns once local buckling initiated; and multi-directional earthquake loading causing bi-axial bending in columns. More information on the test specimen and results can be found on the E-Defense web site, www.bosai.go.jp/hyogo/ehyogo/, or by contacting Yuichi Matsuoka, [email protected].

A blind analysis contest is underway, with more than 52 sub-missions by groups of design professionals, researchers and students from around the world. Fourteen entries were sub-mitted from the US. Winners and statistics on the accuracy of predictions will be announced by E-Defense in December 2007. In addition, the writers are using this building as a case study to investigate how well US performance-based design guidelines (e.g., ASCE-41-06, FEMA-351) character-ize collapse. These results will be available in 2008.

SEAONC members witnessing the collapse test and partici-pating in the NEES/E-Defense research planning meeting included Jerry Hajjar, Helmut Krawinkler, Walterio Lopez, Stephen Mahin, Bruce Maison, James Malley, Steven Mc-Cabe, Kurt McMullen and Troy Morgan. Other Americans included Charles Roeder, Keri Ryan, and Bozidar Stojadi-novic. Planned future tests using the E-Defense shaking table of US-designed structures include a multistory wood residential apartment building, a reinforced concrete bridge column, a concentrically braced steel frames, and innovative energy dissipative frame with uplifting base plates, and a seismically isolated building. For more information on the NEES/E-Defense Collaborative Earthquake Engineering Research Program see http://www.nees.org/NEES-NIED/.
