Basics of Strut and Tie Modeling



Royce Floyd, P.E., Ph.D.
Associate Professor - University of Oklahoma



This presentation will provide a brief history and general overview of strut and tie modeling based on the ACI 318 Building Code Requirements for Structural Concrete and Commentary. It will include discussion of situations where a strut and tie model is appropriate, strut and tie model development, and calculation of strut and tie model strength. The presentation will also include limited discussion of detailing required to satisfy ACI 318. A deep beam will be examined as an application of strut and tie modeling for design.

Learning Objectives:

  • Identify discontinuity regions in a concrete structure
  • Explain how to develop a strut and tie model
  • Describe the ACI 318-19 requirements for struts, ties, and nodal zones
  • Apply a strut and tie model to design a deep beam


Dr. Royce Floyd is an Associate Professor in the School of Civil Engineering and Environmental Science at the University of Oklahoma in Norman, Oklahoma. He earned his B.S in 2008 and Ph.D. in 2012 from the University of Arkansas. His research focuses on prestressed and reinforced concrete structures using self-consolidating concrete, lightweight self-consolidating concrete, and ultra-high performance concrete, and he is author or co-author of more than 30 technical journal articles on these topics. He teaches courses in reinforced concrete, prestressed concrete, and structural wood design at OU. Royce is a member of the American Society of Civil Engineers, Precast/Prestressed Concrete Institute, and American Concrete Institute, where he is active on several technical committees.
