Abstract
In recent years, investigation on FRP rods for prestressing tendons both for high strength and high resistance to corrosion, lightweight, nonconducting, and nonmagnetic properties is increasing. Anchorage systems are often not completely reliable because the characteristic of orthotropic material of FRP with high strength for loads parallel to the axis while a low capacity in normal direction to axis doesn’t allow to use anchorage systems typically used for steel. This paper presents experimental experiences on anchorage systems for FRP rods. Firstly, the behaviour of anchorages with metallic tubular and filled resin around the FRP rod, adopted in tensile tests of Carbon and Glass FRP rods is investigated. Then, anchorage for prestressing FRP rods with experimental tests on clamp and split wedge anchorage types is analysed. Results of experimental campaign are shown and discussed with the aim to provide recommendations for the future research.
