Project ID:	FHWA-PROJ-11-0188
Project Name:	Optimized Shear Stud Spacing for Precast Deck Panel Construction
Status:	Active
Contact:	Last Name: Ocel First Name: Justin Telephone: 202-493-3080 E-mail: justin.ocel@dot.gov
Organization:	Federal Highway Administration - Turner-Fairbank Highway Research Center (TFHRC)
Office:	Office of Infrastructure Research and Development
Team:	Bridge and Foundation Engineering Team
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.
Laboratories:	Structures Laboratory
Start Date:	June 1, 2011
End Date:	June 1, 2014
Funding Amount:	$500,000.00
FHWA Program Name:	High-Performing Steel Bridge
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.
