HIGHER BLOCK STRENGTH - LOWER COSTS
What do you use as your default design strength for masonry? Have you checked with local suppliers to see what is commonly available? Masonry strengths can vary widely, but new findings show the design strengths may be higher than what engineers typically assume.
In the April 2019 SE University session, Cathleen Jacinto presented Lintels for Masonry Walls. Cathleen reviewed the behavior and load distribution of lintels and masonry walls with openings and discussed practical design and detailing strategies to achieve high performing lintels. Cathleen also explained the advantages of analyzing masonry walls with finite element software, and shared findings on what engineers can safely assume for the design strength of masonry.
Typically during design, the engineer does not know the exact block strength that will be supplied on site, and to minimize costs we often specify the minimum block strength of 1900 psi, thus giving an f'm of 1500 psi. However, Cathleen shared that these lower strength masonry blocks are not even available from most suppliers, and in most areas of the country, suppliers provide masonry blocks with a minimum block strength of 3750 psi. This allows the engineer to assume an f'm of 2500 psi without any additional costs to the project. Cathleen shared a website that her company, FORSE Consulting, has created to monitor masonry strengths across the country. Click

CFS STUD PACKS VS HSS
Have you encountered a design where you just can't seem to make a stud pack work sensibly without using an over the top amount of studs or having to increase the thickness? When is it appropriate to stick with a cold-formed stud pack, and when should you consider using another option such as an HSS section?
In the May 2019 SE University session, Roger LaBoube, PhD, PE, from Missouri University of Science and Technology, presented Built-Up Member Design (Cold-Formed Steel). During the session, Roger reviewed the applicable cold-formed steel standards for framing members vs. other cold-formed applications, discussed economical solutions for stud packs, and walked through a design example of a built-up box beam that is not specifically enabled by the current design standards.
D110 presents a design solution which results in each jamb stud in the stud pack having the same tributary area as a typical stud. However, as Roger pointed out, this can lead to an inefficient design in some cases, as shown to the right.
SEU SPEAKER INSPIRES ORGANIZATIONS:
RICHMOND SPCA AND THE LAND CONSERVANCY
OF SAN LUIS OBISPO COUNTY
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. To learn more about the organizations that SE University speakers have chosen, please read our
SEU Speaker Inspires Blog Posts
In June 2019, SE University welcomed Lori Koch, PE, from American Wood Council, to present 2018 National Design Specification (NDS) Changes. Lori designated the Richmond SPCA (https://richmondspca.org/) for the SEU Speaker Inspires donation of the month. French Fry
Lori shared that she chose this organization because: "They are a great local no kill shelter here in Richmond where I live and they provided me with my slightly chubby but very fluffy and cute boy, French Fry, as seen in this photo."
In July 2019, SE University welcomed John Lawson, PE, SE, from Cal Poly - San Luis Obispo, to present Engineering Tilt-Up: Design Provisions Born from Past Experience. John designated The Land Conservancy of San Luis Obsipo County (www.lcslo.org) for the SEU Speaker Inspires donation of the month.
John shared that he made this selection because: "I love this local organization as it preserves important open space and natural habitats while developing an educational outreach program called Learning Among the Oaks for elementary school children that fosters leadership and stewardship."
Thank you, Lori and John, for helping structural engineers with your SE University session, and for your designations of Richmond SPCA and The Land Conservancy of San Luis Obispo County as our SEU Speaker Inspires Organizations of the Month!

COMING NEXT TO SE UNIVERSITY:
INTRODUCING DESIGN GUIDE 21 -
WELDED CONNECTIONS, SECOND EDITION
On August 14th
, Duane Miller, PE, from The Lincoln Electric Company, will present Introducing Design Guide 21 - Welded Connections, Second Edition
for SE University
. This session will be held from 12:30 - 2:00 pm EDT.
Handouts and registration emails for this session will be sent to SE University companies on Friday, August 9th.
The American Institute of Steel Construction (AISC) Design Guide 21, Welded Connections-A Primer for Engineers, was updated as a second edition in 2017. This SE University webinar will be presented by the author of the Design Guide, Duane Miller, PE, and will focus on the new materials that were included in the updated publication.
The latest edition of the Design Guide has greatly expanded coverage on Special Welding Applications, and Problems and Fixes. The webinar will cover new material that was not in the first edition, including the special applications of welding on embed plates, butter welding, heat shrinking, and welding on members to be hot dipped galvanized. In the Problems and Fixes portion, practical solutions to unexpected situations will be discussed, including repair of cut edges, out-of-tolerance weld joints, repair of mill induced discontinuities, welds made without inspection, and more.
SEU BIM FORUM: REVIT FOR STRUCTURAL ENGINEERS - PART 3
On August 28st, Betsy Werra, from E.L.Werra Consulting, will present
SEU BIM Forum - Revit for Structural Engineers - Part 3
. This session will be held from 12:30 - 1:30 pm EDT.
Handouts and registration emails for this session will be sent to SE University companies on Friday, August 23rd.
This SEU BIM Forum session is the third in a 3-part series that is meant for structural engineers and managers who use Revit Structure for viewing/printing purposes and are not as familiar with modeling in the program. This session will focus on the basics of the visibility displays within Revit Structure.
During the session, Betsy will focus on a number of items including viewing linked Revit files, explaining the visibility of worksets, phases, families, parameters, view ranges, crop regions, and visibility overrides. A variety of other topics related to the view control bar settings, Revit visibility hierarchy, and printing dialog box settings will also be presented.
