Practical Applications forBuckling Restrained Braced Frames
Join us for a non-proprietary presentationon buckling-restrained braced (BRB) framesfocusing on interesting projects around thePuget Sound area including:
The Casad Dam intake retrofit nearBremerton where stainless steel BRBsare submerged in the fore bay.
Seattle Seahawks Practice Facility inRenton where a multi-tier BRB framewas used for this design-build pre-fabricated metal building.
VA Hospital Nursing Tower retrofit inSeattle. This retrofit removed andreplaced the existing braces with newBRBs. In addition, BRBs are usedbetween adjacent buildings to preventpounding.
Eastside Catholic School in Sammamishwhere BRB frames were used as themain lateral-load-resisting system.
The discussion will include a brief history ofbuckling restrained braces including:
where they came from
how they work
where they are used
what they typically cost
If time permits, interesting and currentresearch projects will be discussedincluding “eccentric” BRB frames andpairing BRB frames with reinforcedconcrete frames.

From the Board: The Six Prescriptions for Successtimes the best project is theone we didn’t take.
Rx 2: Scope of Services
Execute a written agreementwith a scope of services thatpermits us to fulfill client ex-pectations and meet our firm'sperformance policy at a feethat is fair to both parties.
This prescription advocates fora clear, well-written documentoutlining those services thatwe expect to provide, thosethat we don’t, and our expec-tations regarding fee andschedule. This communicationcan occur through checklistsor in less structured formats.Form is not the point; clearlymatching up expectationswith our client is the point.
Rx3: Contract for Quality,Profit, and Risk Allocation
Execute a mutually agreedupon written contract foreach project.
As we all know, contracts canbe complicated and for manyof us they are not part of ourday-to-day responsibilities. It isimportant, however, thatsomeone be responsible tonegotiate a fair contract—onethat provides a fair balance ofrisk and reward. If the con-tract we have signed has com-mitted us to extraordinary risk,we need to be clear aboutwhat that risk is, and howbest to actively mitigate it.
Rx 4: Contract DocumentQuality Assurance
Apply a systematic qualityassurance and control processto the production of contractdocuments in order to meetour client’s requirements andour community's standard ofcare.
This is the prescription thatspeaks to each of us in termsof what we do every day. Itasks that we each do what wecan to produce the highestquality engineering servicesand contract documents pos-sible. Because each of us
works on different projects,with different clients, withindifferent firms, it is not possi-ble (or desirable) to define asingle path toward improvedquality. As firms, we can (andshould) do what we can toimprove the quality of servicesprovided by our officesthrough; education and train-ing, documentation of bestpractices, facilitating an envi-ronment of open communica-tion, etc. Ultimately, as profes-sionals, each of us needs tofind our own unique ap-proach to continuously im-prove the quality of our ser-vice—and to minimize our pro-fessional risk.
Rx 5: Construction PhaseServices
Include adequate construc-tion phase services as part ofour scope of services in orderto confirm that the designintent is properly executed,thereby minimizing design/construction inconsistencies.
Professional negligence issuesfrequently become apparentduring construction. To bothconfirm that the contractorcorrectly interprets our designintent and to ensure that wewill have the opportunity tomanage disputes as they arise,we must be involved duringthe construction phase of theproject. That involvementstarts with having appropriateconstruction support servicesincluded in our scope of ser-vices. To manage risk withthese services requires thatwe provide them well, accu-rately, and timely, while pay-ing close attention to issuesthat may be “graduating” intoclaims.
Rx 6: Early Action Plan
Respond to problems or po-tential disputes as quickly aspossible and in a manner thatpromotes open communica-tion and contributes to earlyresolution.
Continued on Page 3
the title and description ofeach of the Six Prescriptionsas recorded in SERMC train-ing materials, followed by mycommentary.
Rx 1: Evaluation of Risk
Perform design services onlyafter we have reviewed andassessed the requirementsand risks of a project andhave decided we have thecapability and readiness tomeet client expectations.
With 20/20 hindsight, it isoften clear that projects thatturned into problems weredestined to be problems fromthe beginning—we just choseto ignore the signs. The firstprescription is about taking amoment, before we agree toprovide professional serviceson a project, to consider thesigns—the people and condi-tions involved.
What do we know about theowner … Have they done thiskind of project before? Havewe worked with them be-fore? What has that experi-ence taught us? Are they ade-quately financed to do thejob?
What about the project …Does this project type have aconsistent record of claims?Are there unusual technicalrisks? Can we somehow miti-gate them?
What about us … Do we havethe right experience and ex-pertise to do this project? Dowe have enough time to doit? Is there enough fee to doit right?
What about the other designteam members … Do weknow them? Can they de-liver? Can we be successful ifthey don’t?
While most of us will gener-ally conclude that the risksassociated with a potentialproject are manageable,there are circumstanceswhere this is not true. Some-

The Six Prescriptions for Suc-cess are still good medicine forrisk management.
I had the opportunity lastweek to participate in theTexas Centennial ASCE pro-gram. I was part of a panelthat made presentations andanswered questions regardingthe general topics of risk andclaims management. A por-tion of the program was a re-view of the “Six Prescriptionsfor Success” that was devel-oped by the Structural Engi-neers Risk Management Coun-cil (SERMC). For those of youthat are unfamiliar withSERMC, it was formed, in theearly 1990’s, by DPIC, a profes-sional liability carrier, and acollection of their insuredstructural engineers, to ad-dress the high incidence ofnegligence claims associatedwith the practice of structuralengineering. SERMC devel-oped a number of interestingrisk management programsbefore the organization wasultimately discontinued. Onesuch program was the “SixPrescriptions for Success.”
The Six Prescriptions are a setof guidelines through thepractice of which structuralengineers can minimize theirprofessional practice risk.While they were developedover twenty years ago, theirmessage is just as relevant to-day as it was then. At KPFFwe have found the simplemessages of the Six Prescrip-tions to be a great frameworkaround which to structureongoing education about riskmanagement. What follows is

September Meeting Recap
-by Peter Somers
The September dinner meeting fea-tured an engaging presentation byJason Black and Emily George ofKPFF Consulting Engineers on theFederal Center South Building 1202project. This one-of-a-kind, High Per-formance Green Building, recentlyreceived an NCSEA Engineering Ex-cellence Award, among many otherdesign and construction accolades.The program began with Jason, aprincipal with KPFF and current Seat-tle Chapter Director, providing thebackground for the three-story,206,000 square foot, $72 million pro-ject that now serves as the headquar-ters for the Seattle District of the U.S.Army Corps of Engineers. The design-build project, funded through the2009 American Recovery and Rein-vestment Act, included several struc-tural challenges that were solved us-ing innovative structural solutionsand included a very interesting pro-gram for materials reuse.
Situated along the Duwamish River inSeattle, the site features approxi-mately 150 feet of soft alluvium fillover consolidated glacial deposits.The foundation included driven steelpipe piles and a series of stone col-umn ground improvements along theriver front to reduce the risk of lateralspreading associated with the highpotential for liquefaction. Embeddedwithin the steel piles are geothermalloops that account for a significantportion of the building’s heating andcooling capacity.
As with most federal projects, thebuilding design criteria included pro-
visions for blast resistance and protectionagainst progressive collapse. To satisfythese criteria, the exterior structure fea-tures a “dia-grid” system of three-storysloping columns and horizontal beams,configured as multiple overlapping trian-gles to provide alternative load pathsinvolving cantilevered trusses to supportthe building loads if an individual columnis compromised. Compared with tradi-tional welded rectilinear moment framesystems for progressive collapse resis-tance, this dia-grid system resulted inapproximately 30 percent less steel ton-nage, fewer piles, and a substantiallyreduced time for erection.
Emily, an Associate with KPFF and theproject manager, then described perhapsthe most interesting feature of the pro-ject which is a central commons areathat was constructed with a significantportion of reclaimed lumber salvagedfrom the 1940s era, wood-framed ware-house previously located on the buildingsite. The warehouse, approximately 300feet wide by 1,100 feet long, yieldedover 300,000 board feet of high gradeDouglas-fir timbers and decking. Thematerial was carefully deconstructed,
then transported to a lumber yard inFerndale, Washington, for cataloging,grading, and preparation for reuse.The salvaged lumber provided thecolumns, purlins, and decking used forthe new building. The floor systemconsisted of a concrete slab overwood decking on timber purlins sup-ported by structural steel girders.
Tolerance in the purlins due to check-ing, warping, twisting, and sagging ofthe 70 year old material was providedby an innovative system of rabbetnotches along the top corners of thebeam that resulted in horizontal andvertical uniformity in the decking sup-port. Taking advantage of the con-crete slab for increased structural ca-pacity, the purlins were designed as acomposite system with the slab usinglag screws as the shear transfer. Apreconstruction testing program byKPFF and the general contractor, Sel-len Construction, demonstrated thatthe composite system had capacitysubstantially exceeding the requireddesign loading.
The project, which was awarded anddesigned at the height of the reces-sion, with a lot of interest and compe-tition among the local design commu-nity, is a clear demonstration of howinnovation and collaboration are criti-cal aspects of winning design-buildprojects and then successfully seeingthem through completion.

Rx 6: Early Action Plan
When a potential problem arises, ourfirst step should be to seek counseling.No claim situation should be facedalone. While in each of our firms theprotocol for that communication maybe different, usually the managingprincipal, or another partner, will bethe likely choice for that counsel.When dealing with problems, try tostay open and communicative—notdefensive—and work to solve the prob-
lem. Remember that identifying prob-lems early and working creatively tosolve them is a proven opportunity tobuild relationships. It can be the mosteffective marketing that we do.
In closing, I would like to suggest thatrisk management is not somethingseparate from the practice of engi-neering, but quite the opposite. De-sign and construction problems, alongwith the practice risk that those prob-lems can create, are an integral part ofwhat we do. Practicing our profession
requires a solid understanding of thatrisk—where it comes from and whatcan be done about it. If you have aninterest in this topic, you might wantto consider joining other members ofSEAW with a similar interest at an up-coming Professional Practices Commit-tee meeting.

YMF Corner-by Tyler Kurz
Most engineers who have been successful intheir careers can probably look back to a men-tor somewhere along the way who was instru-mental in guiding them on their path to suc-cess. I know that I have been one of the morefortunate engineers to have had good men-tors helping me along early in my career.
As the economy begins to pick up again, moreand more younger engineers are being hired
into firms and thrown right into the fire. These firms need youngengineers to quickly surpass the steep learning curve that existsbetween school and professional practice. Coming out of therecession has created a new market where clients have gottenused to expecting more for less, with tighter budgets and time-lines. Because of this, much of the mentoring that once occurredhas been sidelined. Project managers who feel these same pres-sures have less time to teach. There is also an experience gap thathas been created, interrupting the once natural flow betweenmentors and the mentored. For this reason it has become moreimportant for younger engineers to network, and to have placesoutside of their own offices to talk about problems they are fac-ing and how to come up with solutions for them.
This problem has not gone unnoticed by either NCSEA or SEAW.Recently, the NCSEA has put a large emphasis on supporting anddeveloping young member groups under the various memberorganizations. They have put together resources outlining howto start, maintain, and or improve these young member groups,and have seen a rapid increase nationwide in the number ofyoung member groups that exist. The SEAW Seattle Chapter YMFhas been fortunate to have received support from our chapter formany years. The Seattle Chapter understands the importance ofthe YMF and has provided the necessary funding and support.More recently, the SEAW Seattle Chapter has even started to en-courage committee members from the various technical commit-tees to attend the monthly happy hours in order to promote in-volvement of younger engineers in the committees. This is a greatstart, and we are continuing to look for more ways to elevate themembers of the YMF within our professional community.
If you would like to become more involved with the SEAW YMF,to attend happy hours, or act as a mentor for younger engineers,please contact us at [email protected]
The Younger Member Forum provides networking and so-cial opportunities to SEAW members 35 and under, as wellas new non-member engineers and students. All SEAWmembers are welcome to participate in YMF functions.

Engineer’s Notes from AfieldI’ve wanted to do this for thirtyyears—walk over the BrooklynBridge. Now that I am really here,it is hard to put my feelings intowords. The first impression I gotwas “The Ages Past.” There werethe cables, the feel of the massivestonework, and the steel framingall fashioned for a purpose by oneof the icons of my own profes-sion.
I walked the 1.3 miles over thebridge with my mother, who is inher late 70s and has an arthriticfoot. I asked Mother if she thoughtshe could make it. I received a coldstare and pursed lips and was told,“I’m walking over this bridge withyou!” So we walked along with half of Brooklyn; people speakingdozens of different languages, and a contingent from the HasidicJewish community. Along the way we met a Jamaican coupleselling Gatorade and water. They kindly offered Mother a chairto rest. We also passed an Italian man and woman taking wed-ding photos with the Bridge in the background. An Americanexperience! “E Pluribus Unum!”
To me, this place is a shrine to the life’s work of a great engineer,the vision of our civil engineering profession, and the history ofAmerica. As a fitting monument to civil engineering—whose vi-sion is service—this bridge is still used every day by thousands ofpeople.
I stood at the first pier and looked up at the archway. My littlepicture might give a hint of the scale of this place. But it does notcapture the immensity or grandeur. Every civil engineer hasheard about this bridge. And like everyone else I have seen mov-ies and studied the design and construction. Yet, nothing pre-pared me for the experience of being in this place. It may soundcrazy, but I was in a state of wonderment when I realized I wastouching steel and stone that Roebling worked. And I realizedsomething: this isn’t just a trip to take when you can. This is aplace we should take our young people in order to inspire themto become civil engineers.
More of my Engineer’s Notes from Afield are published on ourSEAW Facebook Page.

SEFW Fall ForumThe Structural Engineers Founda-tion of Washington is excited toannounce details for its 2013 FallForum, to be held Thursday, No-vember 21, 2013, at BenaroyaHall. This year’s speakers are twoworld leaders in wood construc-tion innovation, Michael Green,AIBC, FRAIC, AIA, Principal at MGArchitecture, and J. Eric Karsh,MEng, P.Eng., Struct.Eng., MIS-tructE, Ing, Principal at EquilibriumConsulting. Their presentation,“Tall Wood—How Timber Sud-denly Decided to Grow Up” willsurely change your perspective on
wood-based design.
Come prepared to learn aboutthe amazing progress timber hasmade as an incredibly sustainableand economical constructionmaterial over the past few dec-ades. As Michael Green calls it the“most technologically advancedmaterial grown by the sun,”wood has earned its place along-side steel and concrete in theconstruction of large institutionaland commercial projects such asinternational airports, municipalhalls, university buildings, andyes, high rises. Wood has gonehigh tech, and if you are in thebuilding business, you shouldknow about it.
To further pique your interest inthis year’s Forum, check out Mi-chael Green’s fascinating TEDtalk, found here: http://www.ted.com/talks/michael_green_why_we_should_build_wooden_skyscrapers.html

University Mentor Night HelpNeededIf you are interested in being amentor for a night for collegestudents, the Puget Sound Engi-neering Council (PSEC) needsyour help! The purpose of thementor night activity has been tobring as many practicing engi-neers together with as manystudents as possible. We are try-ing to inspire the students, mostof whom are freshmen andsophomores as well as highschool seniors, toward a career inengineering. The mentor nightallows engineers to relay theirexperience in the profession andanswer questions posed by stu-dents. The events offer an openforum where the students visitvarious tables and converse withthe mentors. The mentors areasked to bring samples of their
work, such as reports, drawings,models, that will fit on a 30”X30”table top for discussion with thestudents. In the past, some ofthe events have included over 40mentors in 17 disciplines.If you are interested in participat-ing in any of these events, pleaseuse the links to sign up.For more information about theMentor Nights program, visithttp://www.pseconline.org/Events/MentorNights/

1602 Definitions and Notations
Di = Weight of ice in accordance with Chapter 10 of ASCE 7.Wi = Wind-on-ice in accordance with Chapter 10 of ASCE 7.
SECTION 1614 ATMOSPHERIC ICE LOADS1614.1 General. Ice-sensitive structures shall be designed for atmospheric ice loads in accordance withChapter 10 of ASCE 7.
Load combinations involving ice loads
CHANGE SIGNIFICANCE: Section 10.1 of ASCE 7-10 requires atmospheric iceloads to be considered in the design of ice-sensitive structures. The term “ice-sensitive structure” is defined in Section 10.2 of ASCE 7-10 and this definitionhas been added to the IBC. Having the definition in the IBC provides the tech-nical basis for determining which structures are ice-sensitive and are requiredto be designed for ice loads in accordance with the applicable provisions inASCE 7-10. The new Section 1614 references Chapter 10 of ASCE 7-10 for the determination ice loads onthese structures. The LRFD load combinations in Section 1605.2.2 and ASD load combinations in Sec-tion 1605.3.1.2 have been modified to include ice loads where applicable. Where atmospheric ice loadsmust be considered in the design, these code sections cross reference ASCE 7 Section 2.3.4 for LRFD andSection 2.4.3 for ASD respectively.
This new code provision is from the Significant Changes to the International Building Code, 2012 edition,authored by John Henry, PE, Doug Thornburg, AIA, and Jay Woodward. The book is available aticcsafe.org/store. Use ID # 7024S12.
