BENEFITS OF MASONRY LINTELS

Masonry lintels have been used throughout history and have withstood the test of time in many instances. Why is the masonry lintel such an efficient design compared to other available materials? You might think higher strength values can be achieved using other materials, however, masonry lintels built integral with the wall can produce robust and efficient designs in most cases.

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.

As necessary elements within a masonry wall, lintels can be built integral with the wall, or be constructed using other materials. Cathleen reviewed the benefits of using masonry for lintel design as shown on the slide above.

Masonry lintels are typically more easily constructed since there is less coordination between disciplines and the masonry lintel ties in easily with the masonry jamb. Because of this fixity between the lintel and the jamb, a masonry lintel offers a more fixed-end condition than lintels using other materials which increases the strength of the overall wall ... read the full article on our SE University blog.

AVOIDING PROBLEMATIC VIBRATIONS

Have you been involved in the remediation of a building experiencing vibration issues? Do you consider vibrations during your structural analysis to ensure the building occupants will feel comfortable in the structure? ASCE 7 explicitly states that "Structural systems, and members thereof, shall be designed to have adequate stiffness to limit deflections, lateral drift, vibration, or any other deformations that adversely affect the intended use and performance of buildings and other structures." Vibration is an important serviceability issue, and since vibration effects on humans can be subjective, it can sometimes be difficult to foresee.

In the March 2019 SEU session, Geoff Blumber and Ravi Ozarker, PE, P.Eng., from Hexagon PPM, presented Avoiding Vibration Issues in Your Structure. During the session, Geoff explored the types of vibration and vibration sources which should be considered during design, and Ravi examined several strategies for improving dynamic analysis results using structural software, ways to avoid vibration issues during design, and remediation methods.

Ravi stressed that the best way to avoid vibration issues is identifying potential sources of vibration early in the planning phase and then plan strategies to reduce their impact on the structure. Most importantly, he offered the rule of thumb that the mass of the supporting structure be 3 times the mass of vibrating machinery to reduce potential vibration issues..... read the full article on our SE University blog.

SEU SPEAKER INSPIRES ORGANIZATIONS:

CHILDREN'S HOSPITAL OF ORANGE COUNTY AND

LEUKEMIA AND LYMPHOMA SOCIETY

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 .


	Cathleen Jacinto, PE, SE, FORSE Consulting

In April 2019, SE University welcomed Cathleen Jacinto, PE, SE, from FORSE Consulting to present Lintels for Masonry Walls. Cathleen designated the Children's Hospital of Orange County (https://www.choc.org/) for the SEU Speaker Inspires donation of the month.

Cathleen shared that she chose this organization because: "Children's Hospital of Orange County is an amazing organization that has changed the lives of many children and families experiencing their hardest of times. Their brilliant staff and positive environment bring about miracles everyday, for which I am very grateful."


	Roger LaBoube, PhD, PE, Missouri University of Science and Technology

In May 2019, SE University welcomed Roger LaBoube, PhD, PE, from Missouri University of Science and Technology, to present Built-Up Member Design (Cold-Formed Steel). Roger designated the Leukemia and Lymphoma Society (https://www.lls.org/) for the SEU Speaker Inspires donation of the month.

Roger shared: "On June 7, 2003, our daughter Jennifer married Russ. The wedding was a wonderful family event and Karen and I were both extremely happy for Jennifer and Russ. Four short months later, Russ was diagnosed with Hodgkins Lymphoma Stage 4B. After 10 months of treatments, Russ' Hodgkins was forced into remission. Obviously, Karen and I were elated to learn of this news. However, in June 2005, Russ was diagnosed with leukemia. Following more chemotherapy and a stem cell transplant, the leukemia is now in remission. I chose to support LLS to honor both Russ and Jennifer for their fighting spirit and to help others who are also fighting so hard to defeat their cancer. Our family has benefited first hand from both the research and the patient services of the Leukemia and Lymphoma Society."

Thank you, Cathleen and Roger, for helping structural engineers with your SE University session, and for your designations of Children's Hospital of Orange County and Leukemia and Lymphoma Society as our SEU Speaker Inspires Organizations of the Month!

COMING NEXT TO SE UNIVERSITY:

2018 NATIONAL DESIGN SPECIFICATION (NDS) CHANGES

On June 12 , Lori Koch, PE, from American Wood Council, will present our 2018 National Design Specification Changes 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, June 7th.

Session Description:

This presentation will provide an overview of the significant changes for wood design per AWC's National Design Specification (NDS) for Wood Construction. The 2018 NDS is referenced in the 2018 International Building Code and 2018 International Residential Code and used o design woof structures worldwide. The 2018 NDS references ASCE/SEI Standard 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures which includes increased wind loads. Participants will learn about changes in the 2018 NDS to address increased wind loads and gain an overview of the standard. A brief introduction to tall mass timber structures will also be included, with information on the new construction types adopted for the 2021 International Building Code (IBC):

Learning Objectives:

Identify changes in the 2018 NDS.
Identify wind load increases in ASCE 7-16 that affect wood design and construction.
Identify new fastener provisions developed to address increased wind loads.

SEU BIM FORUM: REVIT FOR STRUCTURAL ENGINEERS - PART 1

On June 19, Betsy Werra, from E.L.Werra Consulting, will present SEU BIM Forum - Revit for Structural Engineers - Part 1 . 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, June 14th.

Session Description:

This SEU BIM Forum session is the first 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 how to navigate within Revit Structure.

During the session Betsy will focus on a number of items, including the difference between accessing a file in Revit vs. the Revit Viewer, tips and tricks for opening a view from an existing view, and displaying any area of a Revit Structure model using camera views and section boxes. A variety of other topics related to navigation/viewing/printing will also be presented.
