    Featured Presentation:  Structural Design with Ultra High Performance Concrete (UHPC) (35 minutes)

    Description:

    Ultra-high performance concrete (UHPC) offers enhanced mechanical and durability properties that make it an ideal material for use in the construction, repair, and preservation of our Nation’s highway bridges. Research related to UHPC has been ongoing for the past few decades. The use of UHPC for primary structural members has emerged as a compelling application. The release of the AASHTO LRFD Guide Specification for Structural Design with Ultra-High Performance Concrete is expected to allow designers to begin engaging UHPC. In this presentation, you will learn about the advantages of using UHPC primary structural elements and a brief overview of the general design process including some of the key differences as compared to design with conventional concrete.  Available examples and sample designs will be included.

    Presenters:

    David Garber, Ph.D., P.E.
    Senior Bridge Engineer
    Office of Bridges and Structures
    Federal Highway Administration (FHWA)

     

    David Garber is a Senior Bridge Engineer for FHWA’s Office of Bridges and Structures. In this role, he provides expertise in concrete bridges, UHPC, and load rating to internal and external stakeholders. David previously served as Associate Professor and Interim Department Chair at Florida International University before joining FHWA in June 2023. His previous research, which included large-scale experimental and analytical efforts, focused on the behavior and design of prestressed and reinforced concrete members, accelerated bridge construction, and ultra-high performance concrete (UHPC). David is a licensed Professional Engineer in Florida.

    Rafic Helou, Ph.D.
    Research Structural Engineer
    Office of Research, Development, and Technology
    Federal Highway Administration (FHWA)

    Rafic Helou is a Research Structural Engineer for the FHWA’s Office of Infrastructure,  Research and Development. His research focuses on addressing key challenges in the highway concrete bridge community through innovative, research-based, and experimentally validated solutions. Rafic has been with the FHWA’s Turner-Fairbank Highway Research Center for over nine years in various capacities, stepping into his current role in December 2022. He has extensive expertise in UHPC, has authored numerous publications on its material characterization and structural design, and actively contributes to national efforts to develop UHPC-related guidance. His contributions to the field have been recognized with the 2024 Presidential Early Career Award for Scientists and Engineers (PECASE).
