Talk About Money

Most February Equilibriums for the last 20 years or so have included an article from me, wearing my Treasurer's hat, discussing the financial condition and proposed budgets for SEAW State and SEAW Seattle. I expect you can hardly wait to get this year's version. After a year working on the transition to our new management team who has been busily handling the finances with a different team approach, different bookkeeping program and different database version, I thought I'd be able to present a clear, correct and easily understandable set of reports and budgets. Eh, not so fast. Turns out our organizations are complicated. Who knew? But I can say we've all survived the year and are getting much closer to the goal. The latest reports indicate that both the State and Seattle Chapter are still considerably better than just solvent. The reports also showed us a few items that had been missed and need to be rectified. Stay tuned for the reorganized budgets.

The very successful updated and online SE Refresher course contributed significantly to the Seattle Chapter's 2016 financial success. The very successful Code Update Seminar presented by the Continuing Education Committee's incredible volunteers contributed significantly to the State's 2016 financial success. Thanks to all the organizers and presenters who accomplished this most vital part of SEAW's mission.

I can't miss this opportunity to plug the Structural Engineers Foundation of Washington (SEFW), our 501(c)3 charitable corporation. SEFW presented its Sixth Annual Free Fall Forum featuring "Engineers, Architects, and Builders: A legacy of Innovation in the Pacific Northwest", and is working on plans for the 2017 Forum. The Foundation also maintains the funds for the SEAW Scholarship Program and is focusing on funding SEAW's outreach to students, promoting interest in engineering education. Recent examples include funding of the university student bridge design and construction competition, and grants to high schools for structural engineering related projects. I've always thought of the Foundation as representing individual Structural Engineers, as well as SEAW and SE companies. If each of SEAW's 800+ members donated just $50 annually, the SEFW could do so much more.

Please consider a donation to the Foundation to support scholarships and other activities, especially if your company pays your dues, or if you are a Life Member (like me) and no longer have to pay dues.

At the January Seattle Chapter Board Meeting I asked Joyce Lem, Chair of Disaster Preparedness Committee, to give me a brief write up, "Just a few sentences." President Cary said, "A Picture and a Paragraph." Excellent!

The Board of Directors for the Seattle Chapter has decided to make Equilibrium available to all chapters Statewide. In the coming months we will be adding a section for news and articles from each chapter.

All members are welcome to submit articles to Equilibrium. Write Engineer's Notes from Afield; or summarize an interesting technical design you worked on; write about how you have been successful and increased productivity with an accounting procedures or marketing technique; or write about your experiences in community services.

We are looking for another Member to help with the publication of the Equilibrium. Please contact me at dstaal@staaleng.com if you are interested. Currently, the Equilibrium publication team includes:

YMF Corner
By Morgan Wiese

This past week the YMF happy hour was partnered with ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) and sponsored by PAE consulting engineers at PAE's office in the Bullitt Center, which was also a project they worked on. It was a great event and included a presentation by several people on the design team who described the decisions they had to make and how they had to think differently to achieve the greenest commercial office building. While one of the main goals was a net zero energy building, the building was designed for a 250 year life span. Most buildings today are designed for a life span of 30-50 years, so this long life span brought a new set of challenges that had to be designed around, such as how things could easily be replaced as they met their end of life (like the window system). Thank you to PAE and ASHRAE for hosting this event!

On February 4th, the YMF will be hosting a table at the Puget Sound Engineers Council (PSEC) fair. This is a great event where we will be showing kids in grades K-12 what being a structural engineer means and what we do. If you are interested in volunteering for this event please contact Gino Mazzotti at seawymf@gmail.com.

Good Samaritan Protection for SEAW
By Joyce Lem

Many of you have taken the ATC-20, ATC-45, and SAP classes that teach how to do building safety assessments following a disaster such as a large earthquake. In those classes, you learned that the Washington State Good Samaritan Law provides immunity from liability for individual volunteer engineers, architects, and building inspectors when they are deployed in the field by local jurisdictions after large natural disasters or emergencies. 

Paul Brallier of the SEAW Disaster Preparedness Committee gives testimony in favor of SB 5185 to the Senate State Government Committee.

However, current State law does not provide immunity from liability to the organizations that provide the training for the volunteers, enroll the volunteers and help dispatch them. To "plug this hole" in the law, i.e., extend similar liability protection to organizations such as SEAW, WABO, and the AIA, Senate Bill 5185 and House Bill 1277 have been introduced in the 2017 legislative session. The bills are identical, modifying the language in the existing Good Samaritan Law (RCW 38.52.180) to extend immunity to professional and trade organizations. Read more


Technical Summary: Structural Assessment of Ross Dam Bridge
By Yashar Zafari

The span of interest with the cracking. The span and supports are labeled in yellow. 

During a bridge inspection in 2012, inspectors discovered small cracks along a span of the Ross Intake Bridge. Sealant was applied to the cracks so they could be monitored. In 2014 the cracks were observed to have expanded. Since the Ross Intake Bridge is the only access route to the intake structure, it is important that the bridge be structurally sound. Consequently, Seattle City Light (SCL) tasked CEE 17.2 to assess the structural integrity of the bridge and provide a recommended design option for repair and/or strengthening of the structure.

Technical Summary: Assessing the Tier 1 Evaluation Procedure
By Francesca Galeotti

On February 6, 2016, a 6.4 magnitude earthquake occurred in Taiwan near Tainan City with an epicenter 28 km (17 mi) northeast of Pingtung City in southern Taiwan, in the Meinong District of Kaohsiung. The epicenter (22.92°N, 120.54°E) was located on the Chishan fault, striking at a depth of around 23 km (14 mi). Through a collaborative NSF-funded Rapid project, a team of researchers from the University of Washington and Purdue University conducted two reconnaissance missions to document and analyze the damaged buildings. In total, documentation was collected for 127 buildings including extensive photographing and measurement of damage. Read more


Technical Summary: Seismic Evaluation of Seattle City Light South Service Center Building "A"
By Nicholas Welling, Alex Pangelinan and Dean Zimmermann

Seattle City Light (SCL) requested from Seattle University design team 17.3 an ASCE 41-13 Tier 1 seismic evaluation of the South Service Center Building A as well as an additional deflection analysis that will be used to evaluate the risk of pounding. The building is located in Seattle on 4th Ave. S. and S. Spokane St and serves as one of two power service centers for the City of Seattle. The building was originally constructed in 1924 with building additions made in 1937, 1974 and 2000. A voluntary seismic upgrade was performed in 1999 to retrofit the original building, but SCL wishes to perform an updated seismic evaluation utilizing ASCE 41-13. Read more


Technical Summary: Positive Moment Girder Connections
By Kristina Tsvetanova

Strut-and-tie mechanism in the diaphragm-girder connection

In bridges with precast prestressed concrete girders, the resistance to seismic effects is achieved by the interaction between the columns, the cap beam and the girders. Said components must be connected, such that flexural resistance is provided. The bottom flanges of the two girders, meeting end-to-end at the cap beam, will be under tension and compression, respectively. The tension connection is presently made by extending some of the bottom strands into the cast-in-place cap beam. At this location, the space available is too small for development by bond in the straight strands alone. Since concrete in diaphragm is highly confined it can probably carry high bearing stress and a small bearing area may be possible. Thus, the goal of this project is to create a reliable, effective, as well as practically applicable way of anchoring strands, extended from the girder into the cap beam. Read more
