By: Rafael Sabelli

This month we are announcing the call for entries for the SEAONC Excellence in Structural Engineering Awards. I encourage every member to consider entering this competition, which cel-ebrates our profession and provides us with inspiring glimpses into thought-ful feats of engineering by our peers.

This year it is especially important to celebrate our profession. Many struc-tural engineering practices (and prac-titioners) have had a difficult year. (At the January dinner meeting I jokingly announced a new awards category: Best Cancelled Project. Several in at-tendance thought I was serious.) It is particularly important to remind our-selves that thoughtful engineering is valuable on every project, and that excellent engineering begins with the skill and attention of the practitioner rather than the scale of the project. While our industry endures one of its toughest periods, we should make the effort to retain our core values, includ-ing the love of doing our job well.

The SEAONC Public Relations Commit-tee itself did excellent work last year in the structuring of the program, selec-tion of the jury, and presentation of the winners, both directly to the member-ship and to the public in the San Fran-cisco Business Times. No doubt this year will build on that success. I hope the high quality of the program will be a significant incentive toward your participation.

More information can be found in the announcement in this newsletter.

Los Angeles Convention Center Hotel Presented by: Nabih Youssef, President, Ryan Wilkerson, Senior Vice President, Nabih Youssef Associates

Construction is nearly complete on the iconic Los Angeles Convention Center Hotel, a 56-story nearly $1 billion mixed-use development in downtown Los An-geles, marking a triumph in the use of structural steel. The structure incorporates a special steel plate shear wall lateral system, the first such system of its kind to be used in the US for a building of this height. The system consists of thin steel plates (1⁄4” to 3/8” thick) within fully welded WUF-W moment frames. To stiffen the very slender tower several story-high outrigger trusses are located at the mid-height and top of the tower. The outrigger trusses incorporate 2,200 kip Buckling Restrained Braces to dissipate energy and act as fuse elements to control the maximum force that can be transmitted to the perimeter columns.

A full performance-based design was performed using nonlinear response his-tory analysis procedures. The steel plate shear wall element modeling was devel-oped and calibrated to results of recent tests conducted at leading research insti-

tutions worldwide. As a result of the backstay effect at the podium levels and a reduction in footprint at the 26th floor, the diaphragms at these levels required extensive analysis to ensure essentially elastic performance at the MCE.

The use of the steel plate shear walls resulted in a system which weighed 35% less than a system utilizing a more tra-ditional concrete core wall. The use of the thin steel plate system allowed the owner to capture over 20,000 sf in sell-able floor space within the condominium levels alone com-pared to the concrete core wall option. Additionally, the all-steel framed system was able to be erected three months ahead of schedule.

Due to the unique nature of the design, a rigorous peer re-view was performed by an independent panel of experts. The tremendous collaboration between the design team and peer review panel resulted in the realization of this unique project.

Mary Avenue Bicycle Footbridge, Cupertino, CA

The Mary Avenue Bicycle Footbridge opened on April 30, 2009 and spans an 11-lane portion of I-280 near SR85 in Cupertino, California owned by the City of Cupertino, the bridge closes a gap in the regional bike route by joining sub-urban communities to work centers. The bridge is the first cabled-stayed bridge to cross an interstate highway in Cali-fornia.

The $14.8 million steel bicycle and pedestrian bridge is 500-ft-long by 16.3-ft-wide with a structural steel girder-and-beam superstructure and a 13.5-ft-wide precast concrete panel deck. It is supported by 44 locked-coil stay cables, suspended from two 90-ft steel towers. It has a clear span of 325 ft over the highway and adjacent ramps with 88 ft backspans. The towers and superstructure are composed of roughly 240 tons of steel rolled sections resulting in a bridge weight of just 1,700 lb per linear foot. The abutments and tower foundations include twelve, three-ft-dia, 86-ft-deep, cast-in-drilled-hole piles, with concrete footings and pile caps.

The bridge’s pylons and superstructure are structural steel which delivers some advantages including speed of erection and seismic performance. The reduction in superstructure and pylon mass leads to large decreases lateral forces and foundation size. In the transverse direction, the superstruc-ture was designed using the deck as a shear wall and the non-composite steel edge girders and floor beams as an ec-centrically-based frame (this is similar to a hybrid-coupled shear wall system used in seismically resistant building de-sign).

The diamond-shaped towers optimize the bridge’s torsional performance. This configuration also allowed the towers to be fabricated, transported, and erected in two pieces, spliced only at the strut and the top. The geometry of the half tower was designed to be vertical in its free-standing condition, eliminating the need for temporary or shore bracing. With this approach, each tower was erected in a single night and the complete superstructure was erected in three nights.

The Mary Avenue Bridge was designed to behave elasti-cally under the design-level seismic event and the unique cross-section resulted in wind stability that exceeds design requirements. In addition, the gap between the edge girder and deck enhanced aeroelastic behavior, both for flutter and for vortex shedding excitation. The section is stable up to wind speeds exceeding 120 mph.

John Litzinger, PE served as HNTB’s San Jose Project Man-ager (Associate Vice President – Group Director and former Office Leader) while the structural design was led by Ted Zoli, PE (Vice President – Director of Complex Bridge Ser-vices) in HNTB’s New York office. Mr. Zoli was recently awarded a MacArthur Foundation Fellowship (a ‘Genius Grant’) to pursue advances in bridge design and security.

February Business Forum

Luncheon

MEETING TOPICOutsourcing HR Services to Professional

Employer Organizations (PEOs)

DATE & TIMEWednesday February 17, 2009

12:00 pm – 1:30 pm: lunch/Program

LOCATIONCity Club, San Francisco

155 Sansome St. San Francisco

Speaker: Mark diTargiani, TriNet

Small to midsize business owners often struggle with the complexity, time commitment and costs of employee HR services. Health Care costs for small businesses, in particular, have risen to unprecedented levels and these plans often provide less choice and reduced benefits. Many companies also delegate these responsibilities to overburdened senior staff whose time might be better spent on both procuring and executing jobs. How can smaller businesses compete with the large companies in terms of health care costs and HR benefits while freeing up time to focus on their core business?

One solution is to outsource these HR functions and put the responsibility in the hands of experts. The Profes-sional Employer Organization (PEO) industry grew out of similar economic circumstances in the late 1980’s. By helping businesses manage the cost, time and risks as-sociated with HR and employee benefits, this industry allows thousands of business owners to achieve peace of mind and increased revenue by taking care of this inte-gral business function.

During this presentation, you will learn about the ori-gins of the PEO and the current growth of the industry. You will hear how a PEO can help you save 10-30% on healthcare benefits while offering superior employee-level choices on coverage. You will also see how a PEO can minimize your employee-related liabilities and help guide you through the complicated regulatory require-ments.

You’ll also discover how TriNet, located in San Leandro and a PEO industry leader, takes the model to the next level through integrated systems, a variety of healthcare carriers and plans, other strategic services and high touch service. Lunch will be provided. If you prefer a vegetarian meal please specify this when you send in your registration.

Guide to the Design of Diaphragms, Chords and Collectors – Based on the 2006 IBC and ASCE/SEI 7-05, will be avail-able for purchase through ICC on February 8th. Price is $47 + Tax.

AbstractThe 2006 International Building Code (IBC) presents clear and stringent design criteria for floor and roof diaphragms as necessary to resist wind and seismic loading. However, diaphragms are often one of the most overlooked, underde-signed, and/or inappropriately detailed areas of a building. Diaphragms should respond elastically to design wind and earthquake forces and their failure could lead to nonduc-tile complete or partial collapse of the entire structure. Sur-prisingly, structural engineers are given little guidance on how to design and detail these systems. Simple deep beam models found in textbooks don’t apply for typical building arrangements such as L-shaped buildings, buildings with lateral resistance on three sides, buildings with irregulari-ties, and diaphragms with small or large openings.

Using practical design examples, this short course presents simple analytical and computer modeling methods that ap-propriately account for these and other design conditions. The course is based on a recent NCSEA publication titled Guide to the Design of Diaphragms, Chords and Collec-tors Based on the 2006 IBC and ASCE/SEI 7-05, but expands on the subject matter to address the basics of diaphragms, chords and collectors, commentary on minor changes in the 2009 IBC, and the interpretation of results obtained when using the finite element method.

SEAONC Firm Focus, OLMM Consulting Engineers

By: Sunil Gupta, PhD, SE, President

Since its inception in 1986, OLMM has provided structural engineering services for some of the most notable and com-plex projects in the San Francisco Bay Area and has won awards for many of its projects including the coveted Ex-cellence in Structural Engineering Awards from SEAONC and SEAOC. Just recently, OLMM was recognized by the San Francisco Business Times as one of the 100 fastest-grow-ing private companies in the San Francisco Bay Area. Two of our more significant and recent projects are highlighted below.

Contemporary Jewish Museum, San FranciscoThe new Contemporary Jewish Museum is one of the last crowning pieces in the revitalization of the Yerba Buena district in downtown San Francisco. Bold and striking, the 63,000 square-foot, $47.5 million building by internationally acclaimed architect Daniel Libeskind beautifully adapts and integrates key elements of the historic Jesse Street Pow-er Station.

The building’s contemporary form was inspired by the He-brew phrase L’Chaime (To Life!) and leads to highly com-plex geometry and an irregular struc-ture. Although es-sentially a two level structure, the high-est point in this an-gular building rises almost 70 ft. above the ground level. The complex geom-etry of the building blurred the lines between beams vs. columns and gravity load resisting elements vs. lateral loads resisting elements. Many columns were not vertical but leaning, some in two directions, and the braced frames carried not only the lateral loads but also gravity loads. OLMM responded to the chal-lenges posed by the highly complex geometry of the build-ing by performing 3-dimensional response spectrum dy-namic analyses using SAP2000. Because the braced frames also carry gravity loads, seismic design was performed to ensure nearly-elastic behavior for the maximum credible earthquake.

Another challenge posed by the complex geometry was the de-tailing of the connec-tions. At numerous locations as many as 6 to 8 steel members came together at dif-ferent angles and in different planes requiring creativity and imagination in designing and draw-ing up the connec-

tions. We drew as many as three or four views of key con-nections to convey the intent of the design. But the details begged to be drawn in 3-dimensions. We felt there was too much risk for unre-solved issues and large number of change orders if the project were to be bid and constructed using 2-dimension-al drawings only. To overcome these concerns, OLMM researched and rec-ommended to the client the services of a steel detailer, Dow-co, to develop a 3-dimension steel fabrication model of the structure in TEKLA as we were designing and ‘drawing’ the building. This led to a highly interactive design process. We provided AutoCAD files of our drawings to Dowco as we were developing our design. Dowco used this information to prepare the 3-D TEKLA model and sent this information to us for our review. OLMM then used this information to revise and update its drawings. Using this process we were able to identify and resolve a host of conflicts and potential problems. The TEKLA model was made available to steel bidders for information which led to reduced uncertainties, and, consequently, tighter bids.

OLMMs creative and practical solutions led to a project that was successfully completed within time and budget with only minor changes. The museum opened to wide acclaim in June 2008. OLMM was recently awarded the Outstand-ing Structural Engineering Project Award for the California region by ASCE for this project.

Terminal-2, San Francisco International AirportAs part of Turner Construction and Gensler team, OLMM is the structural engineer for the major seismic upgrade, expansion, and rehabilitation currently underway at Termi-nal-2 of San Francisco International Airport. Scheduled to open in 2011, this 580,000 sq. ft., $380 million fast-track de-sign-build project will add 14 gates for domestic flights.

Terminal-2, the former International Terminal, is comprised of five buildings separated by seismic joints: 12-story steel and concrete frame Cen-tral Terminal and Air Traffic Control Tower originally con-structed in 1950’s with major additions in the early 1980’s, and Boarding Area-D, Concourse, and the North and South Connectors all 2-story steel frame buildings constructed in early 1980’s. Central Terminal is highly irregular with dis-continuous concrete shear walls and braced frames. Our de-tailed seismic analyses and evaluation of this building indi-cated serious seismic deficiencies. The ordinary concentric braced frames of the 2-story buildings as well as other parts of the lateral system were also found to be deficient with re-gards to strength, ductility, and detailing requirements for structures in areas of high seismic activity.

OLMM performed detailed 3-dimensional dynamic analy-ses of the buildings. Seismic strengthening measures were developed to provide reliable and ductile seismic perfor-mance during a major earthquake. Key retrofit measures in-cluded: (i) addition of new pile foundations and developing uplift capacities of existing piles, (ii) strengthening of exist-

ing concrete shear walls and addition of new shear walls, (iii) replacing existing ordinary braced frames with Buck-ling Restrained Braced (BRB) frames, and (iv) strengthening of existing diaphragms with new chords and collectors. In-tegration of new seismic loads resisting elements with the existing structural elements required careful and intricate detailing. Use of BRB’s resulted in lower design base shear with consequent reduction in the number of new pile foun-dations and strengthening of existing beams and columns. This resulted in considerable savings in both construction costs and schedule. This fast-track project, currently under construction, is within budget and ahead of schedule.

ASCE-41 Survey Results By: SEAONC Existing Buildings Committee members: Bruce Maison, Heidi Faison, Mohamed Talaat, Colin Blaney, and Marko Schotanus.

The SEAONC Existing Buildings Committee recently conducted a membership web-based survey to solicit feedback on ASCE/SEI 41-06 Seismic Rehabilitation of Existing Buildings. The purpose was to obtain user opinions which could be used to help direct future actions and make the document better serve industry needs. The survey saw an outstanding response with 204 respondents representing 5% of the SEAOC mem-bership (53% from SEAONC). Thank-you to all who participated.

Data processing and interpretation are ongoing; some initial results are presented below. Preliminary results were also presented in a handout at the ATC-SEI con-ference on existing buildings in December. A final re-port will be issued later this year and summaries will appear in upcoming newsletters. General Opinion. Respondents expressed overall satis-faction with ASCE-41:

State-of-Practice. Several points on how the Standard is currently being used:

Needs. Several high ranking needs are listed below. The number in parentheses is the percentage of re-spondents agreeing with the particular point.

Some Dislikes. Below are several themes that emerged from text statements provided by participants. They had multiple responses, but are not necessarily consen-sus comments. They may identify areas for improve-ment.

Other areas of concern include lack of transparency (e.g., the knowledge “k” factor and the component ductility “m” factor), handling of overturning (section 3.2.10), rationalization of requirements to satisfy multi-ple performance objectives, labor intensive procedures, poor coordination with ASCE-31, lack of global perfor-mance checks, and that the standard often rejects new construction meeting current building code.

• 73% felt it had Strong or Some positive impact on their technical practice (Fig. 1).• 62% gave it a grade of A or B, where B = very good effort, but can have improvements. C = equivalent to most other codes and standards (Fig. 2).

• 48% indicated Low-Rise buildings were the major-ity of projects.• Concrete material dominates (33% indicated that the majority of their projects were concrete struc-tures), followed by Steel (18%), Masonry (12%), and Wood and/or light metal framing (7%). • 40% indicated Linear Static Procedure (LSP) was used on majority of projects.

• Education: Example applications manual (86%); Better informed building officials (82%); and Train-ing classes (79%). • Technical: Calibration with building code (74%); Reconcile NSP and NDP (64%); and Reduce conser-vatism in LSP/LDP criteria (64%). • Document presentation: Correct glitches (60%); and Clarify text and organization (60%).

• Perceived complexity. “it can be simplified for design office use” • Wording and organization. “it is very hard to fol-low and very easy to miss a requirement located in an-other section” • Perceived conservatism.“seems over-conservative at times” “often too conservative” • Revision process. “I dislike that revisions to ASCE 41 are not issued in the manner similar to Code provi-sions”
