Testing of Full Scale Prestressed Beams to Evaluate Shear Key Performance by Richard A. Miller (Professional engineer),George Michael Hlavacs,Todd W. Long Pdf

Adjacent box girder bridges use grouted shear keys to transfer load between beams. These shear keys tend to crack and leak. A full-scale portion of an adjacent box girder bridge was used to test the performance of grouted shear keys under environmental and cyclic loads. Strain gages were placed in the girders and in the shear keys. Displacement gages were placed spanning the shear keys on the top and bottom flanges of the girders. The bridge was subjected to simulated cyclic truck loading as well as environmentally induced thermal loading. The pulse velocity method was employed to find cracks in shear keys. Dye penetration was used to confirm the pulse velocity measurements. The total research project consisted of: (a) testing of the current keyway detail using the currently specified nonshrink grout, (b) testing of the current keyway detail but substituting epoxy grout for the nonshrink grout, and (c) testing of a modified keyway detail using nonshrink grout in which the keyway is moved to the neutral axis of the girder. In the first test, the shear keys were grouted in late autumn and cracked soon after casting, before any simulated vehicle loading had been applied.

Design of FRP Systems for Strengthening Concrete Girders in Shear by Abdeldjelil Belarbi Pdf

TRB's National Cooperative Highway Research Program (NCHRP) Report 678: Design of FRP Systems for Strengthening Concrete Girders in Shear offers suggested design guidelines for concrete girders strengthened in shear using externally bonded Fiber-Reinforced Polymer (FRP) systems. The guidelines address the strengthening schemes and application of the FRP systems and their contribution to shear capacity of reinforced and prestressed concrete girders. The guidelines are supplemented by design examples to illustrate their use for concrete beams strengthened with different FRP systems. Appendix A of NCHRP Report 678, which contains the research agency's final report, provides further elaboration on the work performed in this project. Appendix A: Research Description and Findings, is only available online.

High-performance/high-strength Lightweight Concrete for Bridge Girders and Decks by Thomas E. Cousins,Carin Louise Roberts-Wollmann,Michael Carey Brown Pdf

"TRB's National Cooperative Highway Research Program (NCHRP) Report 733: High-Performance/High-Strength Lightweight Concrete for Bridge Girders and Decks presents proposed changes to the American Association of State Highway and Transportation Officials' Load and Resistance Factor Design (LRFD) bridge design and construction specifications to address the use of lightweight concrete in bridge girders and decks. The proposed specifications are designed to help highway agencies evaluate between comparable designs of lightweight and normal weight concrete bridge elements so that an agency's ultimate selection will yield the greatest economic benefit. The attachments contained in the research agency's final report provide elaborations and detail on several aspects of the research. Attachments A and B provide proposed changes to AASHTO LRFD bridge design and bridge construction specifications, respectively; these are included in the print and PDF version of the report. Attachments C through R are available for download below. Attachments C, D, and E contain a detailed literature review, survey results, and a literature summary and the approved work plan, respectively. Attachment C; Attachment D ; Attachment E; Attachments F through M provide details of the experimental program that were not able to be included in the body of this report. Attachment F; Attachment G; Attachment H; Attachment I; Attachment J; Attachment K; Attachment L; Attachment M. Attachments N through Q present design examples of bridges containing lightweight concrete and details of the parametric study. Attachment N; Attachment O; Attachment P; Attachment Q. Attachment R is a detailed reference list."--Publication information.
