|Project Name:||Optimized Shear Stud Spacing for Precast Deck Panel Construction|
Office of Infrastructure Research and Development |
|Team:||Bridge and Foundation Engineering Team|
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.|
|Start Date:||June 1, 2011|
|End Date:||June 1, 2014|
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.
|Test Methodology:||Full-scale experimental|
|Expected Benefits:||Broader use of accelerated bridge construction using steel superstructures.|
|Deliverables:||Name: Final report.|
