This report presents a recommended guide specification for the design of externally bonded Fiber-Reinforced Polymer (FRP) systems for the repair and strengthening of concrete bridge elements. This guide specification addresses the design requirements for members subjected to different loading conditions (e.g., flexure, shear and torsion, and combined axial force and flexure). The guide specification is supplemented by design examples to illustrate its use for different FRP strengthening applications. The guide specification is presented in AASHTO LRFD format to facilitate use and incorporation into the AASHTO LRFD Bridge Design Specification. The material contained in the report should be of immediate interest to state engineers and others involved in the strengthening and repair of concrete structures using FRP composites.
