When designing bracing connections, have you been using a weld ductility factor on welds subjected to shear and transverse loads to allow for adequate redistribution of stresses?  Although there have been multiple tests and papers showing the importance of this factor, some engineers are still unaware of its necessity which can result in underperforming bracing connections.

In the February 2018 SEU presentation Introduction to the Design and Cost of Steel Seismic  Connections – Braced Frames, Patrick Fortney, PhD, PE, SE, P.Eng., from the University of Cincinnati reviewed using the uniform force method in braced frame connections and covered the various strength and detailing requirements for braced frames and the associated costs.  In his presentation, Pat walked through the design of seismic steel connections, which also included many important thoughts on braced connection design, in general.

Pat specifically highlighted the importance of using a weld ductility factor of 1.25 to increase the load for which welds in all bracing connections subjected to shear and transverse loading.  This weld ductility factor accounts for issues with proximity and distortion within the braced frame connection and is necessary to allow adequate force redistribution within the weld..  Pat referenced the 2004 paper by Hewitt and Thornton, Rationale Behind and Proper Application Of the Ductility Factor for Bracing Connections Subjected to Shear and Transverse Loading, as a good resource to further understand the need for this ductility factor.  Although the Code does not specifically require this weld ductility factor, Part 13 of the AISC Steel Manual does recommend using it.

It is important to note that welds that are designed to develop the strength of the gusset plate need not be increased by the weld ductility factor, since the ductility of the plate allows the redistribution of load.  Also, the weld ductility factor does not apply to welds in shear only.  It is the combination of shear and tension on the weld that triggers the need for force redistribution within the bracing connection but only if proximity issues or distortion issues are present.

Many times these bracing connections may be delegated the steel fabricator, however, it is still important for EORs to be aware of the necessity of the weld ductility factor and its relevance in connection design.  Although not specific to seismic systems, Pat’s explanation of the weld ductility factor and its relevance is a welcomed reminder to engineers that may not be familiar with its use, or don’t typically design their own steel connections.

Patrick Fortney, PhD, PE, SE, P.Eng., University of Cinncinati

In January and February of 2018, SE University welcomed back Patrick Fortney, PhD, PE, SE, P.Eng, from the University of Cinncinati, to present Selecting the Appropriate Seismic System for Your Steel Project and Introduction to the Design and Cost of Steel Seismic Connections. In 2017, Patrick nominated Wounded Warrior Project (https://www.woundedwarriorproject.org/) for the SEU Speaker Inspires donation, and has chosen to do the same in 2018.

Patrick previously shared why he chose the WWP: “The mission of the Wounded Warrior Project is to honor and empower wounded warriors who incurred a physical or mental injury, illnesses, or wound, co-incident to military service on or after September 11, 2001. As with most veterans, these veterans served our country not out of any political bent or personal goal; they made selfless commitments to protect and preserve the great freedoms that we as Americans enjoy and vowed to resist anyone acting to take our freedoms from us.

The Wounded Warrior Project not only addresses the physical ailments of these veterans but, takes a holistic approach to helping veterans to once again acclimatize to their private and personal lives; addressing issues not only suffered by the veterans but, by their families as well. I encourage everyone to view the testimonials of the wounded veterans and their families to which this charity has served. We cannot overlook or underestimate the sacrifices made by our veterans.”

Thank you, Patrick, for helping structural engineers with your SE University sessions, and for your designation of Wounded Warrior Project as our SEU Speaker Inspires Organization of the Month!

SE University began the SEU Speaker Inspires program in 2015 as a way to “pay it forward”, enabling our speakers to designate a charity/organization of their choice for SE University to make a donation to help improve our world.

Matt Brown, SE Newport Structural Design, Inc.

In November 2017, Matt Brown, SE, from Newport Structural Design, Inc., gave a talk on Validating Software Results. He chose the North Bay Fire Relief Fund(https://www.redwoodcu.org/northbayfirerelief) for the SEU Speaker Inspires donation of the month.

Matt shared why he chose to support the North Bay Fire Relief Fund: “My reason for choosing this organization is that my own house came dangerously close to burning down during the recent California fires. It made me aware that just because you live in a dense urban area you are still not safe from wildfires, and I feel for the people of Santa Rosa who never knew that they should have to prepare for this, and who lost everything.”

Thank you, Matt, for helping structural engineers with your SE University session, and for your designation of the North Bay Fire Relief Fund as our SEU Speaker Inspires Organizations of the Month!

Kevin Davenport, PE Simpson Strong-Tie

In September 2017, Kevin Davenport, PE, from Simpson Strong-Tie, gave a talk on Code Provisions for Post-Installed Adhesive Anchors into Concrete. He chose both the Hurricane Harvey Relief Fund through the Greater Houston Community Foundation (https://ghcf.org/hurricane-relief/) and the Red Cross – Hurricane Irma Relief Fund (www.redcross.org) for the SEU Speaker Inspires donation of the month.

Kevin shared why he chose to split the donation between these two organizations: “When SE University informed me of the opportunity to donate to a cause, it came right on the heels of two natural disasters that hit close to home and affected many of my co-workers. My company has been contributing both through donations as well as by way of sending volunteers down to affected areas to assist with the recovery effort. So the first thing that came to mind was to select a cause that would continue to support in the recovery efforts for those devastated by these events in TX and FL.”

Thank you, Kevin, for helping structural engineers with your SE University session, and for your designation of the Hurricane Harvey Relief Fund through the Greater Houston Community Foundation and the Red Cross – Hurricane Irma Relief Fund as our SEU Speaker Inspires Organizations of the Month!

Otto Schwarz, PE, SE Ryan Biggs | Clark Davis

In October 2017, Otto Schwarz, PE, SE, from Ryan Biggs | Clark Davis, gave a talk on Post-Tensioned Concrete Analysis and Design. He chose the Habitat for Humanity – Capital District (https://www.habitatcd.org/) for the SEU Speaker Inspires donation of the month.

Otto shared why he chose his local Habitat for Humanity: “I have been lucky enough to have the privilege of having a stable place to call home and the security of knowing that there was a place I could go to be safe and warm, and to prepare for each new day. This may not be the reason for my successes in life, but without it, I could have never made it this far. The ability to thrive and succeed in life requires a stable foundation on which to build, and many do not have that basic need satisfied. Habitat for Humanity fills this need for so many with the help of the work and donations of so many more.”

Thank you, Otto, for helping structural engineers with your SE University session, and for your designation of Habitat for Humanity – Capital District as our SEU Speaker Inspires Organizations of the Month!

SE Solutions was pleased to recently present scholarships to three Purdue University Structures students to help defray the cost of their education.  Máté Opoldusz, William Pollalis, and April Wang were the recipients of the awards.  This is the sixth year that SE Solutions has offered the scholarships.

Purdue University MSCE Students and Scholarship Winners William Pollalis (left), April Wang (middle), Máté Opoldusz (back), and SE Solutions, LLC President, Brian Quinn

Máté Opoldusz received his BS degree in civil engineering from Budapest University of Technology and Economics in Hungary. He completed his MS in Structural Engineering at Budapest University of Technology and Economics in June 2017, where he conducted research into the design method development of seismic resistant rocking structures. He received a Fulbright Scholarship for 2016-2017 academic year to pursue MSCE at Purdue and he is planning to graduate in December 2017. Máté is working as a Graduate Teaching Assistant for the reinforced concrete design class. Upon his graduation, he hopes to find work at a structural engineering firm near California doing building design.

William Pollalis received his BS in Civil engineering from Purdue and will be completing his MSCE this December (2017). He then plans to continue at Purdue, pursuing a PhD. He is currently conducting research on lap splices in reinforced concrete shear walls susceptible to seismic events.

April Y. Wang received her BS in Civil Engineering from Purdue in 2016, and will complete her MSCE at Purdue in May 2018. She is currently working as a graduate research assistant focusing on the behavior and design of concrete-filled composite plate shear walls (CF-CPSW) for use in high-rise buildings, a project sponsored by AISC and the Charles Pankow Foundation. As a high school student, April enjoyed how physics could explain observable phenomena, but wanted to apply physics to leave a lasting, beneficial impact on society. She was drawn to structural engineering because buildings and bridges are beautiful, lasting solutions to the needs of communities, and they can only exist due to the structure behind the aesthetic finishes. April hopes to join a structural engineering firm after graduation and create beautiful solutions.

SE Solutions would like to congratulate each recipient and wish them future success in their fields of study as structural engineers.

Our natural response to seeing our fellow Americans suffering through a natural disaster is, “How can I help?”  But sometimes, that is about as far as we get.  We might donate a few dollars to the Red Cross, or a religious organization that specializes in disaster relief, but we as structural engineers are uniquely equipped to be of help during disaster relief.

Recently, the National Council of Structural Engineers Associations website published How Structural Engineers Can Assist in Natural Disaster Relief Efforts.  This page includes information on how you can be a part of future disaster relief efforts, and provides ways to keep up to date with specialized training seminars, including free webinars from the Applied Technology Council on the ATC-45 Field Manual: Safety Evaluation on Buildings after Windstorms.  The Structural Engineer Emergency Response (SEER) Committee is active in the recovery efforts in Texas and Florida, and you could be positioned to help with the next crisis that may come our way.

Engineers seeking to help with the relief efforts in Texas can apply for a temporary emergency license by visiting the Texas Board of Professional Engineers’ website.  Also, the National Science Foundation is encouraging submissions of proposals seeking to address the changes related to Hurricane Harvey.

Additionally, the National Voluntary Organizations Active in Disaster (VOAD) is a collective organization which draws together various groups who specialize in disaster response.  These organizations are able to quickly mobilize and provide relief to individuals affected by these disasters.  Different organization are active in different parts of the country, so check out their websites to see how you can volunteer through your local chapters or donate necessary supplies.

Ash Norton, Ash Norton Engineering Leadership

In August 2017, Ash Norton, from Ash Norton Engineering Leadership, gave a talk on Digital Presence for Engineers: What are Your Emails Really Saying?  She chose the Kentucky Educational Television (https://www.ket.org/) for the SEU Speaker Inspires donation of the month.

Ash shared why she chose Kentucky Educational Television: “Some of my earliest memories were of watching Sesame Street and other programs on the local public broadcasting station – KET Kentucky Educational Television. Growing up in a poor family from Kentucky, my future was uncertain. However, the high-quality, educational programming that KET provided instilled in me an early love of learning.

This love of learning allowed me to excel in academics – graduating from high school a year early and ultimately earning degrees in chemical engineering and masters of business administration.

Now KET’s programming is diverse and innovative, while still maintaining commitment to its values of Learning, Excellence,and Community.”

Thank you, Ash, for helping structural engineers with your SE University session, and for your designation of Kentucky Educational Television as our SEU Speaker Inspires Organization of the Month!
