  • Bridge Design Principles - Substructure Components

    Credits: 2 PDH

    PDH Course Description:

    This course explores the fundamental principles behind the design and engineering of bridge substructure components, which serve as the essential supporting elements beneath a bridge superstructure. It examines the roles, functions, materials, load transfer mechanisms, and geotechnical considerations involved in the planning and construction of substructures. Emphasis is placed on footings, piers, abutments, pile foundations, soil-structure interaction, and scour protection strategies. 

    The course is structured to guide the practicing engineer through both theoretical design principles and applied engineering practices, with references to modern standards and specifications.

    Topics:

    Upon completing this course, participants will be able to:

    • Identify and explain the primary components of a bridge substructure and their roles in supporting superstructure loads.
    • Analyze soil conditions and apply geotechnical principles to substructure foundation design.
    • Evaluate the selection and performance of shallow and deep foundations including footings, piles, and drilled shafts.
    • Apply design strategies for abutments and piers based on site-specific constraints, structural demands, and environmental exposures.
    • Integrate protective measures for scour, settlement, and seismic activity into substructure design.
