SE Solutions was pleased to recently present scholarships to three Purdue University Structures students to help defray the cost of their education. Mriganabh Boruah, Sarah Bowlin, and Heyi Feng were the recipients of the awards. This is the ninth year that SE Solutions has offered the scholarships.

Mriganabh Boruah is from Assam, India.  He received his bachelor’s degree from the National Institute of Technology Karnataka, Surathkal in 2018 and will be defending his master’s thesis in spring 2021 with a specialization in structural engineering. He had the opportunity to work as a teaching assistant for CE297-Statics for 2 semesters and has worked in the field of non-linear soil-structure interaction in nuclear power plants. His thesis is focused on reducing the computational time in brittle cracking analysis using Adaptive Multi-Time Step Decomposition. He has a job lined up with a structural engineering firm based out of Tulsa, OK and looks forward to being a part of a challenging industry.

Sarah Bowlin graduated with her bachelors degree in civil engineering from Oklahoma State University in May 2019. She plans on graduating with her masters degree from Purdue University in December 2021. She will be staying at Purdue to pursue a PhD in Civil Engineering. Sarah has had the goal of becoming a structural engineer since she was in high school and had the opportunity to take a variety of pre-engineering classes. At Oklahoma State, she was very involved with the Concrete Canoe Team, which sparked her interest in concrete structures. She enjoys learning about the different behaviors and applications for structural concrete, as well as all the other structural materials. She is currently a graduate research assistant focusing on the behavior of unbonded and bonded post-tensioned concrete bridge girders. After finishing school, she would like to find a challenging and rewarding job at a structural engineering firm.

Heyi Feng received his bachelor’s degree in civil engineering at Portland State University in 2019  and will complete his MSCE study with specialization in structural engineering at Purdue University in August 2021. Heyi has been working as a research assistant.  His research focuses on finite element analysis of API 12F tanks, performing failure modes determination and fitness-for service analyses. He is also currently working as an engineering intern at Baker Consulting Group.  Heyi is hoping to start his career with a firm that allows him to design innovative structures right after his  graduation from Purdue.

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

 

Matthew Rechtien, PE, Esq., Walter P. Moore

In February 2021, SE University welcomed Matthew Rechtien, PE, Esq., from Walter P. Moore, to present Engineering Ethics Update: The New Model Code.  In 2020, Matt designated Friends of Perryville Battlefield (https://www.friendsofperryville.org) for our SEU Speaker Inspires donation for the month and he has chosen to do the same in 2021.

Matt shared, “On October 8, 1862, nearly 8,000 Americans fell in the drought-parched Chaplin Hills of Kentucky during the Battle of Perryville. Perryville played a pivotal role in our nation’s most impactful event. Although the clash is oft-forgotten, those Americans should be remembered and that sacred ground, one of the most pristine civil war battlefields remaining, should be protected. The Friends of Perryville Battlefield is committed to both missions, which I am humbled to advance.”

Thank you, Matt, for helping structural engineers with your SE University session, and for your designation of Friends of Perryville Battlefield as our SEU Speaker Inspires Organization of the Month!

AISC 360-16 has some significant changes in the design of connections to rectangular HSS.  Engineers have no doubt noticed the removal of some of the HSS connection design tables, however the limits of applicability included in the design tables became an impetus for AISC to provide a more flexible design process for HSS connections.

In the January 2021 SE University session, Kim Olson, PE, from Nucor and presenting on behalf of the Steel Tube Institute, presented Navigating AISC 360-16 HSS Connection Design.  Kim identified how the prescriptive nature of Chapter K has been changed to more closely match the rest of the Specification.  She also explained the reasoning behind the changes to the limits of applicability and variables in Chapter K and showed how the equations for connecting to the web of a wide flange member from Chapter J can be used to derive similar equations for connecting to rectangular HSS.

The most visible change in AISC 360-16 is the movement away from the prescriptive tables in AISC 360-10 for connecting to rectangular HSS.  Although the tables were quick and useful, they were limited in scope and unique in style to the rest of the specification.  The new design procedure is specified in Section K2.3 of AISC 360-16 which states that “The available strength of connections to rectangular HSS with concentrated loads shall be determined based on the applicable limit states from Chapter J.”

Referring to Chapter J for this procedure allows the engineer the ability to determine the strength of their exact connection without being limited to the prescribed limits previously included in the specification.  More limit states must be checked to determine which controls which is in line with a typical steel connection design.  

In order to more smoothly transfer from the prescriptive tables to the equations for HSS, Kim shared that the Steel Tube Institute has provided Limit State Tables on their website which highlight what was provided previously in AISC 360-10  and guidance for applying the equations in Chapter J of AISC 360-16 to HSS connections.  As you can see below, the left column in black shows 360-10 / 14th Edition Manual and the new 360-16 / 15th Edition Manual is shown in blue text on the right.

The Limit State Tables serve as a transition key from 360-10 to 360-16 and will provide any limits of applicability for each connection as well as any end distance requirements.  For each limit state, connection capacity equation references are shown with variable substitutions specific to HSS members, which is especially helpful when using yield line theory for plastification.

Overall, the usefulness of these new Limit State Tables should alleviate any heartache over the removal of the prescriptive tables for HSS connection design from the AISC manual.  The new guidance on using the equations from Chapter J in AISC 360-16 will allow engineers to determine the capacity of connections whose geometry may not match those present in 360-10 and the design process more closely matches that of typical wide flange connections.  Click to access these Limit State Tables which are available for FREE on the Steel Tube Institute’s website.

Otto Schwarz, PE, SE

In September 2020, SE University welcomed Otto Schwarz, PE, SE, from Ryan Biggs | Clark Davis, to present Concrete Mix Design.  Otto designated CREATE Community Studios (https://createcommunitystudios.org/) and Institute for the Musical Arts (www.ima.org) for our SEU Speaker Inspires donations for the month.

CREATE Community Studios exists to ensure the beneficial experience of art-making be affordable and accessible to everyone. Their goal is to use expressive arts as an equalizer across cultural and economic barriers, and for participants to learn how to use art as an expressive medium to increase their general well-being.

The Institute for the Musical Arts in Goshen, MA supports women and girls in music and music-related businesses.

Otto commented, “I’ve suggested both of these local organizations for two reasons.  The first is that I believe that the arts and the sciences have equal impact on our lives, and a world without either is lacking.  Small, local organizations like these have the most direct and intimate impact on the surrounding communities and the individuals within them.  The second is that it is these same small organizations that will have been disproportionally hit by the COVID-19 epidemic and a dollar donated here has a bigger impact than a dollar donated to an organization that has a national supporting audience. As the economy re-adjusts in response to times like these, it is often the arts that suffer first and the most.  We should strive to ensure they survive.”

Thank you, Otto, for helping structural engineers with your SE University session, and for your designation of CREATE Community Studios and Institute for the Musical Arts as our SEU Speaker Inspires Organizations of the Month!
