This updated course describes Load and Resistance Factor Design (LRFD) for steel highway bridge superstructures. It provides a combination of instructor-led discussions and workshop exercises. The course also includes LRFD theory applied to design examples and illustrates step-by-step LRFD design procedures. The curriculum follows the AASHTO LRFD Bridge Design Specifications, 7th Edition, 2014 (AASHTO LRFD), including the approved 2015 Interims.

The training includes the extensive use of student exercises and example problems to demonstrate overall design, detailing, and construction principles addressed in the reference materials. It affords hands-on experience in LRFD design and detailing of steel highway bridge superstructures.

The curriculum materials are comprised of a comprehensive reference manual (FHWA Publication No. FHWA-NHI-15-047), lecture and workshop exercises intended to promote or enhance a working knowledge of AASHTO LRFD, and a participant workbook for lecture notes and exercises.

The curriculum material includes the following major topics:

*General superstructure design considerations

*Preliminary design concepts for steel I-girder superstructures

*Steel I-girder design


Upon completion of the course, participants will be able to:

  • Describe the bridge superstructure design and construction process in accordance with the current AASHTO LRFD specifications.
  • Apply the appropriate current AASHTO LRFD specification articles dealing with selection of bridge type, size, and location.
  • Apply the appropriate current AASHTO LRFD specification articles dealing with bridge economics.
  • Apply the appropriate current AASHTO LRFD specification articles dealing with bridge materials.
  • Describe the appropriate current AASHTO LRFD specification articles dealing with evolution of bridge design codes.
  • Apply the appropriate current AASHTO LRFD specification articles dealing with bridge loads and load combinations.
  • Apply the appropriate current AASHTO LRFD specification articles dealing with structural analysis.
  • Apply the appropriate current AASHTO LRFD specification articles dealing with steel bridge superstructure design.
  • Demonstrate the use of the current AASHTO LRFD specification requirements for superstructure design through the completion of step-by-step procedures, participant exercises, and design examples.
