Stability Evaluations of Concrete Dams: On-Demand

You must log in to register

Speakers: Robert A. Kline, Jr., P.E., Vice President; and Guy S. Lund, P.E., Principal Engineer, Gannett Fleming, Inc.

PDHs: This webinar is eligible for 2 PDH credits.

Historically, concrete dam analysis focused much of the attention on material property assumptions, which has been and continues to be important. But more recently, the focus is primarily on the modes of failure experienced by these types of dams. This webinar will present a more in-depth review of stability evaluation methods for concrete dams; the basics of which was first presented in the previous webinar entitled, “Introduction to Concrete Gravity Dams.”

This webinar will begin with a brief overview of the origins of rational design methods previously presented in “Introduction to Concrete Gravity Dams.” Other topics consist of: concrete dam construction and potential failure modes, material properties, loading cases, current federal agency criteria, stability analysis methods, simple gravity method, and finite element methods. The purpose of this webinar is to familiarize practitioners with the current state-of-the-practice in evaluating the stability of concrete dams.

Guy S. Lund, P.E.

Principal Civil/Structural Engineer

Schnabel Engineering, LLC

Guy S. Lund, P.E. is a nationally recognized dam safety and structural engineering expert with more than 45 years of experience in the design, analysis, evaluation, and rehabilitation of dams and hydraulic structures. Throughout his career, he has focused on the engineering and safety of concrete dams, including gravity, roller-compacted concrete (RCC), arch, multiple-arch, and buttress dams. His experience comprises the evaluation and design of more than 100 concrete dams, as well as the development of new dam designs, remedial modifications, post-tensioned anchor systems, and concrete buttress rehabilitation projects.

Mr. Lund began his career designing spillways, outlet works, and water conveyance systems and has since become a recognized leader in advanced structural analysis of dams. His expertise includes three-dimensional finite element modeling, static and dynamic analyses, nonlinear numerical methods, risk-informed decision making, potential failure mode analyses, field investigations, construction observation, and preparation of final design and contract documents. He has been a strong advocate for the use of advanced analytical techniques to better understand concrete dam behavior and improve dam safety evaluations.

Mr. Lund is a FERC-approved Independent Consultant and regularly serves on Boards of Consultants, Technical Review Panels, and Dam Expert Review Panels for major dam safety and rehabilitation projects. He has facilitated and participated in numerous risk assessments as a subject matter expert in concrete dams, hydraulic structures, and structural engineering, including internationally significant projects.

Mr. Lund is also a respected educator and industry leader. He has served on the Board of Directors of the United States Society on Dams (USSD), published and presented widely on concrete dam engineering and risk assessment topics, and developed technical workshops for USSD, the Association of State Dam Safety Officials (ASDSO), and the International Commission on Large Dams (ICOLD). He currently instructs industry courses on best practices and the analysis, design, and rehabilitation of concrete gravity and arch dams.
