Abstract:
The efficiency of externally bonded fibre reinforced polymer reinforcement to strengthen or repair existing reinforced concrete structures is compromised due to the difficulty in achieving the full strength of FRP sheets prior to debonding of the sheet from the substrate. Straight FRP anchors feature a number of advantages to solve this problem, but the absence of design equations for FRP anchors demands further investigation. An experimental programme was undertaken to provide a method to design straight FRP anchors. The mathematical equations that define the relationship between the various parameters that influence the anchor behaviour and the fibre rupture capacity of the anchor are described.
