FOREWORD

Guide Specifications for Design of Bonded FRP Systems for Repair and Strengthening of Concrete Bridge Elements, First Edition (2012) is based on two National Cooperative Highway Research Program (NCHRP) reports.

It was primarily developed from NCHRP Report 655, Recommended Guide Specifications for Repair and Strengthening of Concrete Bridge Elements (2010). Subsequently, Section 4, "Members under Shear and Torsion," was modified based on the results of NCHRP Report 678, Design of FRP Systems for Strengthening Concrete Girders in Shear (2011).

Additional background information on the Guide Specifications and specific design examples can be found in the above-mentioned NCHRP documents.
