Author: Belarbi, Abdeldjelil | Size: 6.47 MB | Format: PDF | Quality: Original preprint | Publisher: Transportation Research Board | Year: 2011 | pages: 128 | ISBN: 9780309155311

This report presents design guidelines for concrete girders strengthened in shear using externally bonded Fiber-Reinforced Polymer (FRP) systems. These 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. The guidelines are presented in AASHTO LRFD format to facilitate use and incorporation into the AASHTO "LRFD Bridge Design Specifications." Also, the report presents recommended changes to the AASHTO "LRFD Bridge Design Specifications" to introduce provisions pertaining to the use of FRP systems for strengthening concrete girders in shear. The material contained in the report should be of immediate interest to state bridge engineers and those involved in the strengthening and repair of concrete structures using FRP systems.
