Abstract
Evaluation of Various Anchorage Methods for Externally Bonded FRP
Garrett Goodall
This research will investigate various externally bonded fiber reinforced polymer (FRP) repair methods for concrete bridge structures. Currently, there are different externally bonded FRP methods to repair damages occurs to concrete bridge structure caused by over-height vehicles, corrosion, etc. However, for FRP repair, especially for the shear strengthening application, the biggest concern is the debonding of the FRP wrap over time and there’s a lock of method to evaluate the efficiency of anchorage between FRP wrap and concrete structure. Thus, this research aims at developing a comprehensive method to assess the efficiency of various anchorage methods. Available anchorage systems such as mechanical fasteners, U-anchors, and fiber anchors (also known as spike anchors) will be investigated. For each anchorage system, different factors will be considered including the structural effectiveness of the repair, invasiveness to concrete, cost, installation complexity, maintenance of repair, and repair duration. The goal of this research is to develop an anchor mechanism evaluation method that can be utilized to determine the definitive best option for concrete member repairs for concrete bridges.
