    AISC’s 2020 T.R. Higgins Lectureship Award winner, Bo Dowswell, PE, PhD, will present "Gusset Plates: The Evolution of Simplified Design Models". This lecture provides a brief history of gusset plate design methods before considering current approaches and previewing a new method to predict the compression strength of gusset plates using notional loads.

    "Bo Dowswell's work on gusset plate design is exceptional," said AISC Vice President of Engineering and Research Lawrence F. Kruth, PE. "His research on wrap-around gusset plates is at the forefront of modern engineering. Bo has the unique ability to evaluate constructability aspects of gusset plates as well as the groundbreaking engineering involved."

    About the Speaker

    As a professional engineer, Bo Dowswell’s design practice focuses on steel structures. Currently, he is principal of both SDS Consulting, a design firm, and ARC International, which specializes in research and consulting. Dr. Dowswell is also an adjunct professor at The University of Alabama at Birmingham, where his research and teaching is concentrated on steel connection design. Additionally, he provides consulting services for the AISC Steel Solutions Center.

    Dr. Dowswell is the author of AISC Design Guide 33-Curved Member Design, and he regularly publishes technical articles on steel design. Dowswell is a member of several AISC Committees, including the Committee on Specifications, the Committee on Manuals, the Committee on Research and the Task Group on Industrial Buildings and Nonbuilding Structures. Bo is also a member of Structural Stability Research Council, where his activities are primarily related to connection element and beam stability.

    About the Lecture

    Each year, AISC's T.R. Higgins Lectureship Award recognizes an outstanding lecturer and author whose technical paper or papers, published during the eligibility period, are considered an outstanding contribution to the engineering literature on fabricated structural steel. The award is named for Theodore R. Higgins, former AISC Director of Engineering and Research, who was widely acclaimed for his many contributions to the advancement of engineering technology related to fabricated structural steel.
