Donald Meinheit, PhD, PE, SE Wiss, Janney, Elstner Associates, Inc.

In September 2018, SE University welcomed Donald Meinheit, PhD, PE, SE, from Wiss, Janney, Elstner Associates, Inc., to present Anchors: Design Examples and Qualification/Certification/Inspection. Don has chosen to split his donation between the foundations for ASCE (https://www.ascefoundation.org/), ACI (https://www.acifoundation.org/), PCI (http://pci-foundation.org/), and CRSI (http://crsi-foundation.org/) for the SEU Speaker Inspires donation of the month.

Don shared why he chose these professional organizations: “When in school, whether undergraduate or graduate, knowing how your career will unfold is impossible to imagine. I was recently given the opportunity to discuss a topic that many years ago was not on any radar, but now is an interesting and important design aspect for connecting structural elements together. I credit the ability to learn new things to both the universities I attended and the professional organizations in which I have taken an active role. That is why in addition to the three universities named last month, I have elected to donate the honorarium to the following professional organizations: American Society of Civil Engineers (ASCE), American Concrete Institute (ACI), Prestressed Concrete Institute (PCI), and the Concrete Reinforcing Steel Institute (CRSI) foundations.”

Thank you, Don, for helping structural engineers with your SE University session, and for your designation of the foundations for American Society of Civil Engineers (ASCE), American Concrete Institute (ACI), Prestressed Concrete Institute (PCI), and the Concrete Reinforcing Steel Institute (CRSI) foundations as our SEU Speaker Inspires Organizations of the Month!

Have you considered when and where to use certain font styles in your daily technical documents? Are font styles purely decorative in nature, or do they serve a more meaningful purpose? Which fonts are appropriate for technical writings?

In October 2018, Janel Miller, from the University of Wisconsin at Madison, gave a presentation on Improving Clarity, Coherence, and Conciseness in Technical Writing. Janel reviewed how to prepare coherent documents, engage and persuade readers, and apply principles of concise writing to improve clarity.

Janel also discussed the use of different typeface or font styles which can affect readability and legibility. Janel included the following slide showing the difference between serif and sans-serif fonts.

As you can see, the serif font includes small, decorative flourishes (called serifs) at the ends of the strokes, whereas the sans-serif (or without-serif) typeface does not. These small serifs may seem insignificant, but they actually serve a purpose for serif fonts such as Times or Georgia. Serifs help the reader follow lines of text when reading large blocks of text in print or reports. In contrast, sans-serif fonts, such as Helvetica and Calibri, are easier to read at a distance or on small screens and mobile devices. Sans-serif fonts are recommended for wayfinding signs on roads, presentations in PowerPoint, and text in emails especially when read on mobile devices.

Your font style selection may affect the ability of the audience to read the document accurately and quickly. Be sure to consider whether a serif or sans-serif font would be most applicable in your future technical reports, emails, or on-screen presentations in order to visually assist your audience in reading your technical content.

Is your library lacking in design examples for anchors in concrete? Are you familiar with the code-required inspections and certifications for concrete anchors? Designing anchors in concrete can be complex and time-consuming if done by hand. Given the ever-increasing utility and flexibility of post-installed anchors, having the best resources on your bookshelf can ensure all failure modes are considered, all specifications are clear, and inspection requirements are met.

In the September 2018 SE University session, Donald Meinheit, PE, SE, from Wiss, Janney, Elstner Associates, Inc., concluded a two-part series by presenting Anchors: Design Examples and Qualification/Certification/Inspection. Don reviewed code applications to design problems and why qualification standards exist. He also identified code requirements for installation and inspection certification, and referenced recommended compliance testing.

When designing anchors in concrete, using the most recent guidelines is essential, since the topic is rather new, relatively speaking. Don referenced the most common publications offering guidance on the design of anchors in concrete. Typically, engineers have relied heavily on Chapter 17 in ACI 318 as the primary design reference for anchors, but other important documents include ACI 355.2-07 Qualification of Post-Installed Mechanical Anchors in Concrete and Commentary and ACI 355.4-11 Qualification of Post-Installed Adhesive Anchors in Concrete. These additional resources from ACI are similar to ASTM standards.

ACI also has several publications for purchase which include worked out design examples pertinent to anchors in concrete which include The Reinforced Concrete Design Handbook SP-17 Volume 2, ACI 355.3R-11 Guide for Design of Anchorage to Concrete: Examples Using ACI 318 Appendix D, and ACI 349.2R-14 Guide to the Concrete Capacity Design (CCD) Method – Embedment Design Examples. These combined documents offer over 40 unique examples, not found in other texts, which can guide the engineer through various anchor designs. ACI 349.2R-14 provides solutions for a ductile anchor design for use in nuclear structures.

Don also referenced the CRSI Technical Note CTN-M-3-11 Suggested General Drawing Notes for Adhesive Anchors which was published in 2011 to assist design engineers in coordinating the adhesive anchor design into cohesive construction and installation requirements for the design drawings. Also, the Concrete Anchor Manufacturer Association published Special Inspection Guidelines for Post-Installed Anchors. Both of these documents are available as a free download by clicking on the links above.

Be sure to have these resources on hand for the next time concrete anchors are used on one of your projects. Using the most recent guidelines is essential to meet the code requirements for strength, as well as for installation and inspection.

Anchors in concrete have several different modes of failure when subject to tension or shear loads. Concrete breakouts in tension tend to get the most consideration since the calculations can be more complex depending on various geometric constraints of anchors or anchor groups. For anchor groups in shear, concrete pryout may also be of concern, especially when anchors are short and stocky. At what point does concrete pryout no longer become a design consideration?

In August 2018, Donald Meinheit, PE, SE, from Wiss, Janney, Elstner Associates, Inc., presented Behavior and Design of Anchors in Concrete for SE University. In Part 1 of a two part series, Don covered the different types of anchors, the behavior of anchors in tension and shear, and the various failure modes in tension and shear. Don addressed a question at the end of the session regarding which anchors were prone to concrete pryout failures in shear.

Being familiar with the ratio of the effective embedment depth of the anchor to the diameter of the anchor can help in determining which failure modes will control the design. In normal weight concrete, if this coefficient is greater than 4.5, then concrete pryout in shear is no longer a concern. The short video below features Don addressing the issue of failure due to concrete pryout, and explaining when this failure mode is applicable.

 

Janel Miller University of Wisconsin – Madison

In October 2018, SE University welcomed back Janel Miller, from the University of Wisconsin – Madison, to present Improving Clarity, Coherence, and Conciseness in Technical Writing. Janel designated the Pheasant Branch Conservancy (http://www.pheasantbranch.org/) for the SEU Speaker Inspires donation of the month.

Janel shared why she chose this organization, “The Pheasant Branch Conservancy in Middleton, WI, protects a natural wetland recharged by artesian springs that sustain numerous wildlife and native plants year around. Unfortunately, southwest Wisconsin experienced serious flooding in August, 2018, and several areas of the conservancy were damaged and need to be restored. I am helping with the restoration because natural areas like Pheasant Branch inspire me to remember my role as a steward of our planet and all of its resources.”

Thank you, Janel, for helping structural engineers with your SE University session, and for your designation of the Pheasant Branch Conservancy as our SEU Speaker Inspires Organization 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. Yen-Chen Chiang, Farida Mahmud, and Sokheang Thea were the recipients of the awards. This is the seventh year that SE Solutions has offered the scholarships.

Purdue University Students and Scholarship Winners (from left to right) Farida Mahmud, Yen-Chen Chiang, SE Solutions, LLC President, Brian Quinn, Sokheang Thea

Yen-Chen Chiang received his Bachelor’s degree in Civil Engineering at National Taiwan University in 2016, and he anticipates completing his MSCE degree at Purdue University in May 2019. Yen-Chen’s research focuses on finite element analysis of API 650 petroleum tanks, and investigates the stability of such tanks under wind loading. Yen-Chen is interested in facing challenges, and hopes to participate in innovative projects. He is hoping to start his career right after receiving his Master’s degree in a company that has the potential to bring the next most gorgeous structure to the world.

Farida Mahmud is from Lagos, Nigeria. She received her Bachelor of Science in Civil Engineering from University of Arkansas in 2017, and intends to complete her MSCE at Purdue in May 2019. Currently, she is working on research related to the seismic vulnerability assessment of state bridges in Indiana. As a child, Farida was deeply fascinated by bridges and how they worked. This fascination led her to pursue a degree in civil engineering, and eventually structural engineering. Upon graduation from Purdue, Farida would like to find a job in a structural engineering firm here in the United States where she can have the opportunity to work on innovative and challenging projects.

Sokheang Thea is from Cambodia. In 2014, he received his Bachelor of Science in Civil Engineering from Universiti Teknologi Petronas under the sponsorship of Petronas, Malaysia. Upon graduation, he worked in Malaysia for over 3.5 years in a pioneering structural consultant firm. He is a recipient of the Fulbright Scholarship in 2017 to continue his MS degree in civil engineering at Purdue University, and hopes to finish in May 2019. His interest is on the dynamic response of structures, especially tall buildings. Sokheang completed high school in 2008. During that time there were few opportunities for Cambodian students to pursue their interests in science and engineering, since Cambodia was not that developed. He, nevertheless, chose civil engineering as his major and has loved it ever since. Upon graduation from Purdue, Sokheang hopes to join a creative group of similar-minded engineers or firm to provide innovative/efficient solutions to structural problems both in and outside the USA.

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

In August 2018, SE University welcomed Donald Meinheit, PhD, PE, SE, from Wiss, Janney, Elstner Associates, Inc., to present Behavior and Design of Anchors in Concrete. Don has chosen to split his donation between Purdue University Lyles School of Civil Engineering Graduate Student Scholarships (https://engineering.purdue.edu/CE), University of Illinois – Urbana-Champaign Civil and Environmental Engineering Trust Fund (https://cee.illinois.edu/give/cee-trust), and the University of Texas at Austin Jack Breen and Phil Ferguson Endowment Funds (http://www.caee.utexas.edu/alumni/gift/opportunites) for the SEU Speaker Inspires donation of the month.

Don shared why he chose these three organizations: “At the time I received my engineering education at Purdue, Illinois, and Texas at Austin, I had no idea of where my professional career would lead me. Fortunate for me, my professors were sincere in their commitment to educate young minds for the future. These three universities nurtured me to become a practical structural engineer with an interest in structural research. It is my desire to support those three institutions to continue teaching young minds.”

Thank you, Don, for helping structural engineers with your SE University session, and for your designation of Purdue University Lyles School of Civil Engineering Graduate Student Scholarships, University of Illinois – Urbana-Champaign CEE Trust Fund, and University of Texas at Austin Jack Breen and Phil Ferguson Endowment Funds, as our SEU Speaker Inspires Organizations of the Month!

How often do you consider your ethical obligations as a structural engineer? What does it even mean to be an ethical engineer? Some might think merely abiding by the laws that apply to everyone else within your jurisdiction is considered ethical, but professional engineers have a duty beyond simply following those laws.

In the April 2018 SE University session, Matthew R. Rechtien, PE, Esq., Senior Assistant City Engineer for the City of Ann Arbor, gave a talk on Engineering Law and Ethics Case Studies. Matt’s presentation helped delineate mandatory versus voluntary rules, and how these guidelines help bolster the status of the engineering profession. As the profession is regulated in all 50 states, engineers have responsibilities and privileges, and are required to uphold certain ethical rules or face possible discipline by the governing and other authorities.

Since laws vary by state, Matt focused mainly on the fundamental principles and canons set forth by ASCE, which he believes are the gold standard and reasonably representative of state laws regulating the profession. Matt also reviewed several case studies with some surprising results based on various ethical dilemmas. These case studies can sometimes initiate thoughtful consideration and create awareness on how to avoid unethical business practices within the profession. You can access additional case studies by visiting http://www.asce.org/ethics/ and you can click here to print your own copy of ASCE’s principles and canons. Also, ASCE offers an Ethics Hotline where engineers can get further guidance on complex issues that may arise by calling 1-800-548-2723 x6151.

Often times, structural engineers may zero in on their responsibility to “hold paramount the safety, health, and welfare” of the public by providing sound engineering judgment, however, their ethical obligation runs much deeper. Being aware of the full extent of your responsibilities and privileges as an esteemed member of this profession can minimize future risk and help promote the status of the profession as a whole.

On August 22, 1018, Martha Van Geem, PE, Independent Consultant, presented Challenges of Proposed Requirements in ANSI/ASHRAE/IES Standard 90.1 as a supplemental session for SE University.  Martha reviewed the proposed requirements being considered by ASHRAE in Addendum av and areas of the country which could be affected by the changes. ASHRAE is seeking input on these proposed changes from practicing engineers, architects, and contractors to substantiate if these requirements are technically sound, practical, and cost effective.

Although structural engineers are not typically the lead designer of the thermal requirements for buildings, the implications of these proposed changes would significantly impact the design community as a whole within many climate zones throughout the United States.  Also, the 26 page document is rather complicated and is not constructed in a typical “Code” fashion, but rather requires idyllic, impossible building guidelines followed by a number of exceptions.

In order to ensure these proposed changes are well considered by the design community, ASHRAE is holding a public review until September 17, 2018.  Public comments are welcome on the addendum as a whole, specific sections or specific wording.  Click here to read Addendum av in its entirety.  You can review the instructions for commenting on the Addendum av by clicking here.  In order to provide feedback, you will need to create a login on ASHRAE’s website, and click on the Comments next to BSR/ASHRAE/IES Addendum av to ANSI/ASHRAE/IES Standard 90.1-2016, Energy Standard for Buildings Except Low-Rise Residential Buildings (First Public Review Draft).  You do not need to be a member of ASHRAE to participate in the public review, and creating a login is free of charge.

As licensed structural engineers, we are often times called upon to serve the public by providing our expertise in order to weigh the importance of safety, constructability, and sustainability of construction means and methods within our industry.  Participating in the process may prevent others from dictating the future terms of building construction.

Does your company have a formal mentorship program?  While some larger engineering firms have made efforts to form employee development programs, not all firms have a formal program in place to guide young or even experienced engineers toward needed growth and improvement.  If your company does not offer a mentorship program, make it your goal to seek out your own mentor!

Typically, mentorship programs are most successful when they are driven by the mentee’s desire to self-improve.  Since you are your own best advocate, there is no reason why you can’t acquire your own mentor, even if one is not provided by your company.  This may even work to your advantage, since you will have complete control over who you consider as a possible mentor.

First, consider those within your organization who may be a step ahead of you in the hierarchy of your company.  While it may be tempting to shoot for someone at the top, your mentor should serve as a stepping stone to boost you to the next level of success.  If your company is very small, and there are not many degrees of separation between the top and bottom, you may need to search outside your company.  Often times, professional organizations such as SEI, NCSEA or ASCE offer many opportunities to volunteer for committees where you may meet engineers who could be suitable candidates.

Once you’ve found a potential mentor, simply ask if he/she has the availability to meet with you occasionally to answer questions, gain insight into their daily tasks, and guide you on ways to improve your skills.  Asking another engineer for help, may seem uncomfortable, however, showing an initiative to improve one’s skills is always applauded.  Experienced engineers may not offer unsolicited advice to avoid sounding bossy or self-important, but when asked, their knowledge and past mistakes can be great learning tools for you.

A successful career in engineering takes time and energy to seek out the positive influences and guidance of knowledgeable colleagues who encourage our curiosity.  Without such mentors, success can seem elusive and distant.  Take the initiative, and find your own mentor… it might just launch you into the next phase of your career!
