Anchoring devices for external strengthening systems made of Fiber Reinforced Plastic (FRP) materials represent a solution to avoid or delay debonding phenomena in concrete and masonry strengthened elements. Several types of anchoring devices were tested by researchers and used in real applications in the last years, but clear design indication for estimating the effectiveness of each anchoring type are still not available. Basing on the examination of the available experimental results of bond tests in concrete and masonry specimens externally bonded with FRP materials, this paper is aimed to furnish design indications for calculating the effectiveness of two types of common end anchoring systems in term of theoretical debonding load increase: 1) transversal FRP strips and 2) FRP spike anchors.

Abstract

Anchoring devices for external strengthening systems made of Fiber Reinforced Plastic (FRP) materials represent a solution to avoid or delay debonding phenomena in concrete and masonry strengthened elements. Several types of anchoring devices were tested by researchers and used in real applications in the last years, but clear design indication for estimating the effectiveness of each anchoring type are still not available. Basing on the examination of the available experimental results of bond tests in concrete and masonry specimens externally bonded with FRP materials, this paper is aimed to furnish design indications for calculating the effectiveness of two types of common end anchoring systems in term of theoretical debonding load increase: 1) transversal FRP strips and 2) FRP spike anchors.
