Book Description
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.

Book Description
TRB's National Cooperative Highway Research Program (NCHRP) Report 655: Recommended Guide Specification for the Design of Externally Bonded FRP Systems for Repair and Strengthening of Concrete Bridge Elements examines a recommended guide specification for the design of externally bonded Fiber-Reinforced Polymer (FRP) systems for the repair and strengthening of concrete bridge elements. The report addresses the design requirements for members subjected to different loading conditions including flexure, shear and torsion, and combined axial force and flexure. The recommended guide specification is supplemented by design examples to illustrate its use for different FRP strengthening applications.

Book Description
"Deficiencies in shear resistance are a primary concern in concrete members due to the sudden and unpredictable nature of shear failures. Shear deficiencies in concrete structures can arise due to improper design, long-term deterioration, man-made damages, increases in loads, or as a result of over strengthening in flexure. A number of shear strengthening techniques offer a cost effective means for restoring or enhancing the shear capacity of a concrete member. The use of externally bonded fiber reinforced polymers (FRP) is one such technique that has gained recent recognition for its high strength-to-weight ratio and simplicity of application. The development of this technique relies on experimental testing to better understand the behavior and failure mechanisms. Previous experimental investigations and analytical models/design guidelines were studied to identify and understand the parameters influencing the shear strengthening effect of externally bonded fiber reinforced polymers (FRP). The knowledge acquired from the literature was used to design and carryout a full-scale experimental investigation for further evaluating the effectiveness of externally bonded FRP for shear strengthening. Test specimens consisted of reinforced concrete (RC) and prestressed concrete (PC) girders. Parameters of interest included the effects of: pre-existing damage (cracks), transverse steel (stirrup) reinforcement ratio, FRP strengthening scheme, and methods of FRP anchorage. The experimental results were compared with predictions from existing analytical models and design guidelines. Lastly, an alternative analytical approach was developed which takes into consideration multiple parameters shown to have influence on the FRP shear strengthening effectiveness, but which have not been collectively incorporated in previous models"--Abstract, leaf iii.

Book Description
"These guide specifications are intended for use in the repair and strengthening of reinforced and prestressed concrete highway bridge elements using externally bonded fiber-reinforced polymer (FRP) composite systems. The guide specifications have been updated to better align with ACI 440 strain approaches, and major updates include the following: flanged sections in flexure, prestressed concrete sections, inclusion of factors to account for environmental exposure conditions, near surface mounted (NSM) FRP designs, design of end anchors, detailing of laps and splices, updated approach to FRP concrete interface strain, and inclusion of design examples for shear and flexural strengthening, and confinement. These updated guide specifications also contain detailed design examples, reflecting the latest research and lessons learned from actual field deployments."--Publisher website
