| Roadmap/Focus area(s): | Infrastructure Research and Technology Strategic Plan and Roadmap | |
| Project Description: | This project will collect data to justify modification to the American Association of State Highway and Transportation Officials Load and Resistance Factor Design Bridge Design Specifications in terms of steel composite construction. Specifically, increasing the shear stud spacing beyond 24 inches will be explored. This project will also evaluate if the existing static and fatigue design provisions are adequate. The project will static test composite beams with shear stud spacings of 24, 36, and 48 inches, as well as fatigue test 3 replicates at each of those spacings. | |
| Goals: |
To determine if shear studs can be clustered at spacings exceeding 24 inches as currently dictated in the American Association of State Highway and Transportation Officials Load and Resistance Factor Design Bridge Design Specifications.

| Deliverables: | 1. Name: WORKING TITLE - "Optimized Shear Stud Spacing for Steel Superstructures with Precast Deck Panels" Product Type(s): Technical report Description: The report will outline the test methodology, testing matrix, results attained, and conclusions. 2. Name: Recommended changes to American Association of State Highway and Transportation Officials (AASHTO) Bridge Design Specification Product Type(s): Draft standard, specifications, or guidelines Description: The research will likely justify changes to both the static and fatigue design provisions of shear studs in Section 6 of the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) Bridge Design Specifications. This product will likely be in the form of a ballot item the AASHTO Subcommittee on Bridges and Structures can take up as a business item. | |
